Answer 1

Answer:

4) Back to the Beginning

When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.

5)ANSWER

Green plant --> insect (grasshopper) --> frog --> snake peacock. In the food chain, the green plant is the primary producer by trapping energy from sunlight. 

The insect (grasshopper) is the primary consumers, because they directly consume the green plant. The frog is the secondary consumer, because it eats the grasshopper. The snake, a primary carnivore eats the frog. The peacock is the tertiary carnivore, because it eats the primary carnivore, the snake. Thus, the correct answer is option D.
