Which population increases the amount of soil nutrients available to plants? < br /> < br /> a. a dog that buries a bone in the backyard.< br /> < br /> b. rain forest plants that grow toward the light. < br /> < br /> c. a butterfly that pollinates a flower when eating nectar.< br /> < br /> d. earthworms that decompose an apple that fell from a tree.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
