NEET BIOLOGY

Detailed explanation-1: -Predators have profound effects throughout their ecosystems. Dispersing rich nutrients and seeds from foraging, they influence the structure of ecosystems. And, by controlling the distribution, abundance, and diversity of their prey, they regulate lower species in the food chain, an effect known as trophic cascades.

Detailed explanation-2: -Answer and Explanation: Predation creates stability by maintaining population levels of the prey organisms at constant levels.

Detailed explanation-3: -<br> (iv) Predators do not act as conduits for energy transfer across trophic levels .

Detailed explanation-4: -"Organisms evolve over the long term in response to their enemies, and with increased predation intensity more species evolve.” The second hypothesis is that as biodiversity increased, by chance predators with more complex feeding strategies evolved.
