Answer 1

➭ AnSwer :-

⟹ Biotic factors influence crop production in the following ways :-

1. Earthworms improve the texture of the soil.
2. Microbes such as nitrogen fixing bacteria improve the fertility of the soil.
3. Insects act as predators and keep the number of crops under control.

Answer 2

Explanation:

ANSWER:

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.
