How do biotic and abiotic factors affect crop production ?

Explanation

Biotic factors such as pests, insects and diseases reduce the crop production. A pest causes damage to our crops by feeding. Weeds also reduce crop productivity by competing with the main crop for nutrients and light.
Similarly, abiotic factors such as temperature, wind , rain etc. affect the net crop production. For example droughts and floods have a great impact on crops sometimes, destroying the entire crop.
