Question:
Which of the following act as conduits for energy transfer?
Options:
Predator
Prey
Parasite
All of these
Correct Answer:
Predator
Explanation:
Besides acting as ‘conduits’ for energy transfer across trophic levels, predators play other important roles. They keep prey populations under control. But for predators, prey species could achieve very high population densities and cause ecosystem instability. When certain exotic species are introduced into a geographical area, they become invasive and start spreading fast because the invaded land does not have its natural predators.
