Question

Explain Co-extinctions.

Hint:

"Extinction of one species leads to the extinction of another dependent species" → This is co-extinction.

Answer 1

Definition: Co-extinction refers to the phenomenon in which the extinction of one species leads to the extinction of another species that is closely associated with it. It usually happens when two species are interdependent for survival. Explanation: - Many species exist in ecological relationships such as host–parasite, plant–pollinator, and predator–prey. - If one species becomes extinct, the dependent species also faces extinction because it cannot survive without the other. Examples: \[\begin{array}{rl} \bullet & \text{If a host fish species becomes extinct, its specific parasites also get extinct.} \\ \bullet & \text{If a flowering plant species goes extinct, its specialized pollinator (like a particular bee or butterfly) will also vanish.} \\ \end{array}\] Conclusion: Co-extinction highlights the interconnectedness of ecosystems, showing that the loss of one species can trigger a chain reaction of extinctions.
