Which statement best describes the role of animals in the water and carbon cycles?
animals release carbon dioxide and water vapor as a by-product of cellular respiration.

animals release carbon dioxide and water vapor as a by-product of photosynthesis.

animals take in carbon dioxide and oxygen during cellular respiration.

animals use oxygen to perform photosynthesis and release carbon dioxide as a by-product.

Animals release carbon dioxide and water vapor as a by-product of cellular respiration.

Explanation:

In the course of respiration, Oxygen is taken in by an animal and Carbon dioxide is then released into the atmosphere couple with water as the byproducts of the respiration.

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.

really dont know just need some points
