Best answer: What are 5 major abiotic factors in coral reefs?

Five major abiotic factors in coral reefs are water, temperature, sunlight, salt, and waves. All of these are parts of the coral reef ecosystem that are not alive but have a major impact on the conditions of that ecosystem. All coral reefs are found in ocean waters, mainly in shallow, tropical areas.

What are the 5 major abiotic factors?

The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.

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. Sunlight is one the most important abiotic factors for marine ecosystems.
