The process of growth involves eating food, breaking down food through digestion, absorbing nutrients from food, and building tissue.
What do animals need to grow?
Key concepts include a) animals need adequate food, water, shelter, air, and space to survive; b) plants need nutrients, water, air, light, and a place to grow to survive.
How do animals grow answer?
Answer. The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. … To produce more cells, animal cells divide in two.
How do animals grow larger?
They found that body size tends to increase as animals develop more specialized diets confined to particular habitats. Moreover, the origination of larger sizes coincided with periods of global cooling, and came at the cost of increased extinction risk.
What are three stages of animal growth?
Animals that Grow Up (Simple Life Cycle):
These animals have three stages — before birth, young and adult. The young are typically similar to the parent, just smaller. The young slowly “grow” to become adults.
How animals change and grow?
Reproduction The animal creates new animals like itself. Death The animal’s life ends. Some animals, such as people, get larger as they grow older. Unlike people, some animals go through life cycle changes called metamorphosis (met.
What is growth in animals called?
In biology, “biological growth” is associated with progressive development. An organism’s growth may go on throughout its life, or end when that species is fully mature. An example of biological growth is a plant seed developing into a fully mature tree.
How do animals grow and reproduce?
The whole process of sexual reproduction in animals begins with the formation of sperm from the male and eggs from the female. Next, the sperm and egg join together to form a zygote. Finally, the zygote grows and develops to become a baby animal.
How do animals grow in number?
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
What is the main reason for growth in animals?
Animal growth is determined by a complex variety of factors but these can be reduced to three main categories: the animal’s gene pool, the nutrients with which it is supplied, and its environment. The common factor linking and communicating these is the endocrine system.
How do plants grow and develop?
They grow through a combination of cell growth and cell division (mitosis). The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth).

Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis. Sexual reproduction may involve fertilization inside the body or in the external environment.
What is the process of reproduction in animals?
Most animals reproduce through sexual reproduction, but some animals are capable of asexual reproduction through parthenogenesis, budding, or fragmentation. Following fertilization, an embryo is formed, and animal tissues organize into organ systems; some animals may also undergo incomplete or complete metamorphosis.
Why do animals reproduce short answer?
Animals reproduce to give birth to babies of the same species and ensure that their species are not getting extinct from earth. This is a very important process of maintaining life and ecosystem.
What are the stages of growth in animals?
The four stages of the life cycle of an animal are birth, growth, reproduction and death.
What is growth process?
The growth process thus may be summarized as consisting of a statistical process of nucleation, surface-diffusion-controlled growth of the three-dimensional nuclei, and formation of a network structure and its subsequent filling to give a continuous film.

What is growth Short answer?
Growth refers to the increase in mass and size of a body or organs. It typically occurs through the multiplication of cells and an increase in intracellular substance. Development refers to the physiological and functional maturation of the organism.
How origin influence the growth and development of meat animals?
The firs one is genetic factors, which it includes disease resistance, feed conversion efficiency, breed, and abnormal growth rates. The second most important factor is non-genetic in origin and it encompasses factors like nutrition, management, disease control, and environmental conditions.
How is growth different in plants and animals?
Plants differ from animals in their manner of growth. As young animals mature, all parts of their bodies grow until they reach a genetically determined size for each species. Plant growth, on the other hand, continues throughout the life span of the plant and is restricted to certain meristematic tissue regions only.
How a plant grows step by step?
The stages that plants go through are from seed to sprout, then through vegetative, budding, flowering, and ripening stages. Similarly, the nutritional needs of people and plants change as they grow.
What are the 4 stages of plant growth?
The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.
How do animals and plants depend on each other?
Animals are consumers and they all depend on plants for survival. Some eat plants directly, while others eat animals that eat the plants. In turn, some plants depend on animals to help spread their seed. Decomposing animal carcasses can also provide nutrients for plants to grow.
What are the 7 things plants need to grow?
All plants need these seven things to grow: room to grow, the right temperature, light, water, air, nutrients, and time.
What are the 5 basic needs of animals?

What are the 3 stages of plant growth?
- Seed stage (Seed germination)
- Vegetative stage (Growth)
- Reproductive, flowering and fruit stage.
How do seeds grow?
When a dry seed comes into contact with moist soil or growing media, the seed begins to take up water through the seed coat. As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed.
How do animals survive?
Animals need food, water, shelter, and space to survive. Herbivores can live only where plant food is available. Carnivores can live only where they can catch their food. Omnivores can live in many places because they eat both plants and animals.
How do animals survive in nature?
Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates. These physical features are called called physical adaptations. They makes it possible for the animal to live in a particular place and in a particular way.

The place that a plant or animal lives in is called a habitat . A habitat is the physical area where the animal or plant lives. An organism’s natural habitat has everything it needs to live.
What are two ways of reproduction in animals?
Just as in plants, there are two modes by which animals reproduce. These are: (i) Sexual reproduction, and (ii) Asexual reproduction.
What animal gets pregnant by itself?
Most animals that procreate through parthenogenesis are small invertebrates such as bees, wasps, ants, and aphids, which can alternate between sexual and asexual reproduction. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish or lizards.
What are the 4 types of asexual reproduction?
Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

How do the plants reproduce?
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. The anther is the part of the stamen that contains pollen. This pollen needs to be moved to a part of the pistil called the stigma.
Why do animals want to reproduce?
Reproduction ensures the continuation of the species. Animals will only reproduce with the fittest of the species and choose not to mate with animals with the disease or in periods of drought or lack of food. Some animals require a mate to reproduce, while other species can reproduce alone.
Why do animals reproduce Why is it important for them to reproduce?
The process of reproduction ensures that a plant or animal species does not disappear from Earth. This process is very important in maintaining stability in the ecosystem and for the continuation of life on earth. Had there been no reproduction, all the species would have become extinct.
How do cells grow and develop?
Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly until we become adults. When we are adults many cells mature and become specialised for their particular job in the body. So they don’t make copies of themselves (reproduce) so often.
What animals have 4 stages in their life cycle?
Moths and Butterflies undergo complete Metamorphosis comprising four stages: egg, caterpillar, pupa and adult.
How are plant and animal life cycles similar?
Although each individual animal and plant species has its own specific life cycle, all life cycles are the same in that they begin with birth and end with death. Growth and reproduction are two of the central components of the life cycles of plants and animals.
What is the last stage of every animal?

What are the four life cycle stages Most plants and animals have in common?
3-LS 1-1 Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
How do living things change as they grow?
The cells of living things divide, allowing the living things to grow bigger and to change as they grow. The cells divide to form new cells that are different from the original cells. This growth is controlled by the genes in each cell.
Is an animal growing a physical change?
yes it is a chemical change because there are many chemical changes going inside the body of plant or animal.
