Which activity is most likely a result of a sudden, unexpected change in the environment? A.Plankton populations decreasing B.Whales feeding on plankton C.Crabs migrating to reproduce D.A dog mating to produce offspring

Respuesta :

I would say A, plankton populations decreasing.
I chose that because 1: a lot of organisms feed off of plankton, so that change would decrease not only plankton, but those who feed off of plankton. and 2: the other options are natural, they happen regularly-- plankton don't decrease regularly.
Hope this helps :)
a is the answer trust me
