Invasive species can be a big problem economically and environmentally. This simple food chain illustrates some of the feeding relationships in a (hypothetical) coastal area of Florida that has been heavily impacted by invasive green algae. One of your colleagues has the idea that introducing a new top predator (a big fish from China that will eat little fish) into the area could help to control the invasive green algae. His idea is that the new big fish will eat the small fish, resulting in fewer small crustaceans being eaten, so that there will be more of the crustaceans to eat the invasive algae. Explain the potential problems of your colleagues' plan, including at least two supporting details.

Which element provides strength to the exoskeleton of clams and oysters

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
