Your question: What are abiotic and biotic factors that affect populations?

What are abiotic and biotic factors that effect populations? Abiotic factors are the non-living factors in an environment such as temperature, light, water, and nutrients. Biotic factors are living organisms that are part of an environment.

What are the abiotic factors that affect population?

Environmental factors. Environmental factors that influence populations are divided into two categories – abiotic and biotic factors. Abiotic factors refer to the non-living physical and chemical elements found in an ecosystem such as rainfall, temperature, pH, sunlight, shelter and day length.

What are abiotic and biotic factors that affect communities?

Abiotic factors can be physical or chemical in nature: water, light, temperature, humidity, availability of chemical elements, wind, etc. Biotic factors are the living components of an ecosystem: relationship between organisms, presence of parasites, etc.

What abiotic factors affect biotic factors?

The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment. Hope it helps you !
