Q 4
Question

Look at this food chain: Grass → Grasshopper → Frog → Snake. If frogs disappear from this ecosystem, what will happen to the population of grasshoppers and snakes? Why?

Show answer Hide answer
Answer
Grasshoppers would increase and snakes would decrease.

Explanation

  • Frogs eat grasshoppers, so without frogs, grasshoppers rise.
  • Snakes eat frogs, so without frogs, snakes lose their food.
  • So the snake population would fall.
  • This shows how removing one link upsets the whole chain.
Remove one link and the whole food chain is disturbed.
