Question

Imagine a species of grass carp (a freshwater fish) that inhabits a pond in mid Missouri along with many other fish and invertebrate organisms. The carp routinely increases the turbidity (reduces the clarity) of the water by sweeping its fin through the silt. This behaviors has no effect on the carp itself, but significantly reduces the ability for other species to find food.

Between the grass carp and the other species, this is likely an example pf which type of interaction?

a. commensalism

b. amensalism

c. parasitism

d. interspecific competition

e. mutualism

Now imagine that for one particular fish species, the increase in turbidity caused by the grass carp leads to an increase in its ability to subdue prey by giving it stealth ambush. For the grass carp and other fish species, this would most likely be an example of which type of interaction?

a. intraspecific competition

b. predation

c. herbivory

d. amensalism

e. commensalism

Answer 1

Ans.1. Option B is the correct answer.

EXPLANATIONS:- It is an example of amensalism. In this type of interaction, one species does get benefitted nor harmed and the other species got harmed or loss. This type of interaction is called as amensalism. It is 0, - type of interaction.

Ans.2. Option E is the correct answer .

EXPLANATIONS:- It is an example of the commensalism. It is +,0 type of interaction in which one species got benefitted and other not got harmed nor it benefitted. It remains neutral. For example grass carp remains neutral and the other fishes got benefitted.
