Question

Sometime higher plant and animal perform anaerobic respiration instead of aerobic respiration if there is depletion in oxygen level in the surrounding

Answer 1

Yes,

Sometimes higher group of organism perform anaerobic respiration. This is because sometimes higher group of organism lacks oxygen or required instant energy at a time causing anaerobic respiration in our body producing Lactic acid.

E.g.

When we run in a race we required energy instantly causing to perform Anaerobic respiration. This leads to pain in muscles due to accumlation of lactic acid.

Answer 2

Explanation:

Some higher plants, animals under goes anaerobic respiration, when their deficiency of oxygen in the surrounding. For example, anaerobic respiration occurs during seed germination when the soil is submerged under water. Similarly, our muscle cells also perform anaerobic respiration while do heavy exercise. Due to this, less amount of energy is produced in our body.
