Question

describe the impact of crabs going extinct in the ecosystem. who will be positively impacted and negatively impact?

Answer 1

It will definitely have an impact in the food web as the predators of crabs such as dog fish , sharks , octopus and different other aquatic as well as the birds also are the predators of crab ( so definitely they will have a negative impact ) and the prey of crabs includes small fishes at the ocean bed and snails so if the crab goes extinct it will not have that much positive impact on the prey of crabs ( in easier words population increases )


I guess this will satisfy you question
Have a nice day
