Wildlife conservation and soil conservation are closely related.

evs - i the environment and us threatened species need of conservation conservation of soil and wild life sleeping time animal senses sense organs in animals

  1. True

  2. False

Show answer
Correct Option: A
Explanation:
Wildlife conservation, forest conservation and soil conservation are greatly related as wildlife depend on forests because forests are only home and shelter for them so wildlife would be conserved if forests conservation is done. If any animals die its humus helps the plant to grow because it gives so many minerals and many animals help in germination of seeds. Then forests would be conserved if wildlife conservation is done. Then plant's roots hold the soil and soil degradation is greatly reduced which is done due to forests conservation. And we know it takes million years to form soil. So wildlife conservation, soil conservation and forest conservation are closely related. Each of them are interdependent.
So, the correct answer is 'True'.
