What are the strengths and weaknesses of this photosynthesis?

A good reason to have photosynthesis: helps flowers, plants and grass grow and helps us have crops to eat (and for farmers to sell)

If we lost photosynthesis (the not-so-great part): plants wouldn't grow like they are supposed to, they might even die off. You won't be able to have enough healthy herbs and vegetables to fight off the bad things in life.

photosynthesis creates food for plants and converts carbon dioxide into oxygen. However, photosynthesis relies on the sun for energy.

Explanation:

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.
