Q 2
Question

Imagine a situation where all the organisms that carry out photosynthesis on the earth have disappeared. What would be the impact of this on living organisms?

Show answer Hide answer
Answer
Without photosynthesis, food and oxygen would run out and most life would end.

Explanation

  • Photosynthesising plants are the main makers of food.
  • Animals that eat plants would have nothing to eat.
  • Animals that eat other animals would also lose their food.
  • Oxygen in the air would slowly fall, as plants release it.
All food chains start with plants, so life cannot go on without them.
