The population size of a predator species is directly controlled by the population size of it's prey. If the predator has no prey the population size will go down because they have no food.
Variation means difference in genetic makeup between individuals within a specie.
sand dunes
because it is and sand dunes get deposited

Answer:
Chlorophyll "a"
Explanation:
The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.
