Question

A mangrove community has following food chain:

Mangrove --> mangrove tree crab--> roseate spoonbill--> American crocodile

Which population would be most likely to increase if roseate spoonbills disappeared from the community?

A) American crocodile
B) Roseate spoonbill
C) Mangrove
D) Mangrove tree crab

Answer 1

D) Mangrove tree crab. There would be a drop in the predators that feed on them. Crocodile populations would drop due to food shortage, and mangroves might also suffer from the high crab populations, so only D is correct.
