What are the abiotic factors of ecosystem?
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
What is more important to an ecosystem abiotic factors or biotic factors?

What are biotic and abiotic factors in an ecosystem?
Description. Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem.
How biotic factors depend on abiotic factors?
Abiotic factors do not depend on biotic factors for survival Biotic factors depend on abiotic factors for survival. Changes in abiotic factors may limit the growth and development of plants and animals. … Because biotic factors are very dependent on abiotic factors there is always uncertainty.
Why is it important for organisms to compete for resources in an ecosystem?
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).
