Question

2. Give a reason why earth worms come out of the soil when it has rained.for wallowing it?​

Answer 1

Explanation:

Oxygen diffuses easily through air, and the soil stays aerobic because oxygen comes in from the surface. But after a rain, the soil pores and the worm burrows fill with water. The worms can't get enough oxygen when the soil is flooded, so they come to the surface to breathe.
