What are biotic and abiotic factors in coral reefs?
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. Sunlight is one the most important abiotic factors for marine ecosystems.

What are 10 abiotic factors in a biome?
Examples of Abiotic Factors
- Soil composition.
- Salinity (the concentration of salt in water)
What are 3 abiotic factors in a coral reef?
- Light: Corals need a moderate amount of sunlight in order to survive.
- Depth: Reef building corals must live where there are moderate amounts of light.
- Water temperature: Remember that corals thrive in the warm waters of the tropics.
- Salinity: Salinity is usually measured in parts per thousand (ppt).
Is Desert abiotic or biotic?

Can coral grow inside a human?
This has led one diver to ask me, “Can coral polyps grow in my skin?” The short answer is, “No, it is not physiologically possible for coral, hydroid or sponge cells to live on or within the human body.” This constellation of requirements is extremely unlikely to exist on or within the body.
Do corals eat?
Corals get their food from algae living in their tissues or by capturing and digesting prey. Corals also eat by catching tiny floating animals called zooplankton. At night, coral polyps come out of their skeletons to feed, stretching their long, stinging tentacles to capture critters that are floating by.
What are 4 examples of abiotic factors?
Abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.
What are 3 examples of abiotic?
Examples of abiotic factors are water, air, soil, sunlight, and minerals.
Do corals have eyes?
