Question

Gulls & Oystercatchers Weak Strong Predatory snail Herbivorous Herbivorous snails limpets GooseneckMussels Intertidal algae barnacle

Using the scenario and interaction web from above, what types of direct interactions and 3-species interaction modules occur along the way? Please help me answer, thank you.

a) Apparent competition

b) Trophic chain

e) Exploitative competition

d) All of the above

Answer 1

Apparent competition occurs indirectly between 2 individuals that are both prey to a predator This is not considered to be real

In this model apparent competition exists in the case of herbivorous snails and limpets

Explotiative competition:Indirect interaction through shared limited resources

This also exists in the case of intertidal algae

This represents a trophies chain from the producers to predators

SO OPTION IS D
