Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then <em>discovered</em>) to emerge is proof of such.
Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness.

Coastal Ocean!
Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.
This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.
NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.
