Answer 2

After a heavy rain, earthworms come to the surface because:

• The earthworm is a member of the kingdom of animals and phylum Annelida.
• The earthworm is segmented and the body is moist. it absorbs the oxygen through their moist skin surface.
• Earthworm absorbs oxygen under the soil because the soil is porous which facilitates the absorption of oxygen.
• After the heavy rain, soil pores become clogged with water and the availability of oxygen is reduced. so, the earthworm comes to the surface for gaseous exchange.
