Abiotic Factors. There are multiple abiotic factors that affect coral reefs (figure 8-1). … If there is too little light, then the zooxanthellae will not be able to photosynthesize and produce food for corals. Too much light, especially ultraviolet (UV), may cause corals to expel zooxanthellae, causing them to bleach.

What are some biotic and abiotic factors in a lake ecosystem?
A pond or lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Pond and lake ecosystems are a prime example of lentic ecosystems. Lentic refers to stationary or relatively still water, from the Latin lentus, which means sluggish.
What are the effects of biotic and abiotic factors in a coral reef?
What are the biotic and abiotic factors in a coral reef? Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature.
What factors influence coral reef health?
There are numerous stress factors that can detrimentally impact the health of coral reefs. These include changes in sea surface temperature (SST) and salinity (SSS), sea level and ocean currents, nutrient availability and/or sedimen- tation rates, and light levels or surface seawater aragonite saturation (Xarag).
What is an biotic element?
Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals. Examples Water, light, wind, soil, humidity, minerals, gases. All living things — autotrophs and heterotrophs — plants, animals, fungi, bacteria.
How do the biotic factors and abiotic factors interact with each other?
Complete step by step answer: Biotic factors include all the living organisms while abiotic factors include non-living factors such as light, air, soil, rock, minerals, water etc. Abiotic factors help living organisms to survive. … Rock, soil and water interact with biotic factors to provide them nutrition.
Is sand a biotic or abiotic factor?
Some examples of Abiotic factors are the sun, rocks, water, and sand. Biotic factors are living organisms that affect other living organisms. Some examples of Biotic factors are fish, insects, and animals.
Is oxygen a abiotic factor?
Abiotic factorsare the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
What are 10 biotic factors of the ocean?
