Answer 1

Answer:

aerobic respiration

Explanation:

Answer 2

________________________________________________________________

Amoeba , paramecium and simple multicellular organisms breathe through the body surface by the process of Diffusion .

________________________________

• Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.

________________________________

• In amoeba as well as paramecium respiration takes place through its cell membrane also called the plasma membrane .

• Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion .

• The oxygen gas diffused inside the body is used up by the amoeba .

• In the body, the oxygen gas absorbed is used to break down the complex food material into simple molecules .

• During these metabolic reactions in the body of amoeba, the oxygen gas is converted into carbon dioxide gas .

• The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion .

• Since amoeba needs oxygen for respiration, the type of respiration is aerobic respiration .
