Answer 1

Breathing:

1. Breathing is the process of moving air into and out of the lungs in order to promote gas exchange with the internal environment, primarily to remove carbon dioxide and inhale oxygen.
2. Organs that help the following organisms to breathe are;

(a) Fish: A fish's gills are used to breathe.

(b) Snake: A snake breathes through the glottis, which opens the passage to the windpipe or trachea when it takes a breath.

(c) Cranes: Cranes, like humans, breathe via their lungs.

(d) Earthworm: Earthworms breathe through their skin's mucous.

(e) Man: A man inhales and exhales through his lungs.

(f) Banyan tree: Carbon dioxide is taken up by the banyan tree. They use broad holes called stomata to absorb the air around them.

(g) Caterpillar: Caterpillars breathe using spiracles, which are small pores that run along the length of their bodies.
