7. The correct answer is photosynthesis.
Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).
8. The correct answer is primary consumers.
Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.
9. The correct answer is: they are different populations of fish.
Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.
By breaking down dead organisms and animal waste. Which releases nutrients back into the environment
<span>Many bacteria and archaea are able to transfer genes among themselves outside of typical reproduction. This blurs the line between species as they are defined in the Linnaean system.</span>
<span>There are several instance today of how science can be used to make decisions. One very good example is forensic determination of a baby paternity. In a situation where there is controversy over the paternity of a child, DNA analysis can be used to determine the true father of a child.</span><span />
<span>There are three phases of clnic study and one post approval phase required by the Food and Drug Administration (FDA) for a New Drug Application (NDA). Phase IV which is a common stipulation by the FDA includes continual evaluation of the drug after approval has been granted.</span><span />
