Question

1). Plants and animals can survive without us.
a). True
b). false

Answer 1

Answer:

Absolutely true.

Some animals like cats will perish without humans.

But humans can't live without plants.

Answer 2

This is a true statement.

• Plants are autotrophs that make their food by photosynthesis. In this process, carbon dioxide is used and oxygen is released.
• On the other hand, animals release carbon dioxide into the atmosphere by respiration. They use oxygen to carry out various metabolic activities. This oxygen comes from plants while plants use carbon dioxide released by animals during respiration process.
• Hence, both plants and animals can survive without us.
