Identify the definition of biomagnification.
1.the accumulation over time of a chemical in a living organism.
2.the process of energy increasing in amount as you move up through the trophic levels in a food chain.
3.the accumulation of a chemical from food exposure that results in a concentration that is greater in higher trophic levels.
4.the process of using a microscope to inspect a living organism.

Answer:

3

Explanation:

basically biomagnification describes how toxins get in the body of a trophic level and increase over time as larger quantity of that trophic level are needed since only 10% of energy is transferred form one trophic level to the other.

Do mutations always lead to evolution?

Yes, because mutations create adaptations that give a competitive advantage.

No, because most mutations lead to death of the organism.

No, because some mutations happen in the body cells, so they are not passed on.

Yes, because there would be no change in populations without mutations.

Reproductive isolation occurs when

A- some catastrophic event greatly reduces the size of the population

B- The gene pool of different populations have become very diversified

C-members of different populations can no longer meet successfully

D-small numbers of individual moves and starts in new population
