Answer:
the prey of crabs would be positively affected, and the predators of crabs would take a negative effect to the extinction of crabs
Explanation:
small clams, starfish, snails, worms, squid, mussels, shrimp and small fish would all be positively affected if crabs were to go extinct, because all that is listed are part of a crabs diet, for both large and small crabs. the ones which would be negatively affected would be the predators of crabs, such as cobia, eels, striped bass, jellyfish, red drum, American eels, sharks, dogfish, sea rays, and smaller fish. they would take a negative affect to the extinction of crabs because as said before, these are all predators of crabs, so the extinction would remove them from their diet, forcing them to find other sources for food

Explanation:
Density independent factors exert their influences on population size, and cause erratic shifts on population size. Small population generally at the risk of being wiped out by the density independent factors.
Some examples of these factor includes natural disasters (such as floods, earthquake, and tornados), fires, and pollution effects. The chances of dying of density independent factors not depends on how many individuals are presented in the population.
