Answer 1

ANSWER

Breathing Process In Earthworms

• Earthworms breathe through their skin.

• The gases in the atmosphere enter the earthworm's skin through diffusion.

• Oxygen is taken in by the circulatory system.

• Carbon dioxide dissolves out of the blood and then goes back to the skin.

                                                                               

Breathing Process In Plants

• Plants require CO₂ and give out O₂.

• Gases in the atmosphere enter the leaves through diffusion.

• Stomata is the breathing organ for plants.

• They are present under the surface of the leaves.

• Carbon dioxide released during respiration is utilized by plants for photosynthesis.

                                                                               

Breathing Process In Fishes

• Gills are the breathing organs in fishes.

• They get their oxygen which is dissolved in water.

• The fish drinks the water and force it into their gills

• The gills absorb the oxygen and circulate it in the body.

• CO₂ in the blood passes out through the gills into the water.
