Which of the following could result in the founder effect? a. the establishment of a small colony of nonhuman primates on an isolated island off the coast of africab. the introduction of a new predator that rapidly decreases the population of nonvenomous snakes on a caribbean islandc. the formation of a land bridge between two barrier islands in south carolina allowing for interbreeding between two populations of salamandersd. the inbreeding and increased incidence of disease among captive bengal tigers in zoos throughout the worlde. the annual migration of birds to a common mating ground in mexico from geographically distinct locations

The answer is A. The establishment of a small colony of nonhuman primates on an isolated island.

Explanation:

The founder effect refers to the effect that a small initial number of settling individuals has on the genetic variability of that initial population, which loses much of their original variability due to the many genes that are absent from those few initial settlers. As they reproduce and the population grows it becomes distinct from the source population in the mainland and may lead to a new variety or even a new species given enough time.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
