Question

A population of zooplankton is exposed to a small number of predatory fish that feed on the larger-sized (adult) zooplankton. Which of the following predictions would most likely occur based on the principles of natural selection?

A. Adult zooplankton will start to reach sexual maturity when they are still relatively small.
B. The predatory fish will evolve smaller mouths so that they do not drive their prey to extinction.
C. The zooplankton will become sexually mature at larger sizes.
D. The predatory fish will evolve poor eyesight so as to preserve their food supply.
E. The first and the third listed responses are both good predictions.

Answer 1

Answer:A. Adult zooplankton will start to reach sexual maturity when they are still relatively small.

Explanation: Zooplankton are sometimes heterotrophs or denitrifying organisms they range from microscopic organisms to large species. Examples include jellyfish,amphipods etc Zooplankton are known to be plankton (drifters) within large bodies of water like the SEA(SALT WATER) and RIVERS(FRESH WATER) by moderate water currents.Adult zooplankton are known to start to reach sexual maturity when they are still relatively small or sometimes during their plankton stage.
