Q1. How do biotic and abiotic factors affect crop production?
Crop production can go down due to:
Biotic factors such as insects, nematodes, and diseases reduce crop production. Insects feed on the crop thus destroying it.
Abiotic factors are natural factors like temperature, salinity, waterlogging which also reduces crop production. Different crops require a different range of temperature, hence, the wrong temperature can cause thee crop production to go down.
