ECOLOGICAL FACTORS

biotic factors; in the previous section we look at the variety of pest attacking farm animals and crops. pest constitute biotic ecological factors and contribute substantially to loss of crops both on the farm and in the storage especially in developing countries where farming and food crops storage techniques are still largely primitive. it is important to note that. not all biotic components of the environment have deleterious effects on crop production. some have positive effect. earthworms that digs tunnel in the soil. nitrogen-fixing bacteria all improve the soil for high crops production.strong and domestic animals like cow.camel and donkey are also used on the farm farm to plow the ground. and irrigating device and transport crops

CLIMATE: climate ecological factor I.e temperature. rainfall. wind.humidity. and duration of sunshine determine the type and production of crops of each environment
