Explanation

In an agricultural ecosystem, there are two types of factors: biotic and abiotic. Biotic factors are all the living things. Abiotic factors are the non-living things like water, air, and rocks.

Crop pests are biotic factors because they are living organisms. Pests include insects, rodents, and birds that eat or damage crops. These living creatures interact with plants and affect how well crops grow.

Soil pH measures how acidic or alkaline the soil is, which is not alive. Temperature and rainfall are weather conditions, not living things. All three of these are abiotic factors in the farming environment.
