William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter. Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.

Biosphere and atmosphere.

Explanation:

Biosphere refers to the living organisms lives on the earth surface. All plants takes carbon in the form of carbondioxide gas from the atmosphere for the production of glucose in the process of photosynthesis and releases carbondioxide by the living organism in the process of respiration as a waste product. We can conclude from this discussion that photosynthesis acts to transfer carbon between two Earth systems such as biosphere and atmosphere.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

i am positive it is c. condensing but i may be wrong
