Question

what will happen if the number of insects eating birds reduces? Write any two effects?

Answer 1

Assuming that the question meant ‘What will happen if the number of “Insect-eating” birds decreases?’, there will be a change in the eco-system chain.

Garden pests and insects are usually at their highest number during spring and in late summer. These insects feed on the plants and leaves and destroy them. The birds that feed on the insects indirectly help in saving the plants and increase their growth.

1.    If there is a decrease in the “insect-eating” birds, then there will be an increase in the destruction of the plants in the garden, backyards, crop-plants in fields etc.

2.    When there is an increase in the plants and less damage to them, there will be an increase in the biomass also, which is helpful for the environment.

 

Answer 2

hi thank you for asking the question
if the insect eating birds some how reduce or we can say at a verge of extinction then it can disturb the ecosystem.The birds are a natural predator of those insects. if they decrease in number the number of the insects will increase and they can harm useful crops and fruits etc.another thing that will happen is that animals such as cats which are predator of these birds,they will lose there food in nature and will have to change there prey to some other specie if it doesn't happen then there number will start to decrease too eventually
i hope my answer was helpful
