What are 2 biotic factors in a coral reef?

What are two biotic 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 are the biotic factors of a coral reef?

What are 5 major abiotic factors in coral reefs?

Five major abiotic factors in coral reefs are water, temperature, sunlight, salt, and waves.

What are 2 abiotic factors that affect the abundance and distribution of corals?

Their distribution is highly dependent on abiotic factors such as light, water temperature, and salinity. LIGHT: Coral diversity is low near the surface, reaches a maximum between 15 and 30 m, and then drops again with increasing depth. TEMPERATURE: Corals require water temperature ranging between 18 C and 30 C.
