What is the significance of penguins as indicator species?

Question

2)they are the first birds to migrate
3)they show the health of the ecosystems
4)they are unaffected by climate change

Answer 1

The correct answer is:

3) they show the health of the ecosystems.

Penguins are considered indicator species because their well-being reflects the health of their marine environments. Changes in their population sizes, breeding success, and behavior can indicate shifts in the ecosystem, often due to factors like climate change, pollution, and changes in prey availability. This makes them valuable for understanding the broader health of the ecosystem in which they live.
