Question

A. The direct interaction between fish and larval dragonfly leads to what, if any, change in larval dragonfly density (i.e., increase, decrease, no change, cannot be determined)?

B. The indirect interaction between fish and dragonfly leads to what, if any, change in dragonfly density.

C. The direct interaction between pollinator and plants leads to what, if any, change in plant density.

D. The indirect interaction between fish and plants leads to what, if any, change in plant density.

E. Is this is an example of top-down or bottom-up control? Explain.

F. What is this specific type of effect called?

Explanation / Answer

Ans- a- the direct interaction between fish and larval dragonfly will have negative effects on larval density as fish will act as a predator and will decrease larval density.

Ans-B- the indirect interaction between fish and dragonfly will have negative effects on dragonfly density because fish will destroy the larval stage of dragonfly and this will lead to decrease in dragonfly density.

Ans-C- the pollinators are known to spread the pollens of pollinating plants and thus help in fertilisation. So the direct interaction between them will have positive effect on plant density.

Ans-D- fish is predator for the dragonfly larva so reduce dragonfly indirectly. Decrease in dragonfly density will lead to increase in pollinators density as their predator density will be less so more plant will be fertilised so there will be increase in plant density.
