Breathing in aquatic animals and animals
living under the soil​

Answer 1

Answer:

the animals that live in the soil breathe by the air and oxygen dissolved in the soil . It can be proved but putting a lump of soil in water that will form bubbles that are made of air this proves that soil has air dissolved which is useful to breath by animals.

Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).
