Why is it important that seeds disperse away from the parent plant?

answer:

this is  important  because if the  seedsare not  dispersed, many germinating seedlings will  grow  very close to theparent plant. this results in competition between every one of the seedlings as well as with the  parent plant. the competition is for light, space, water and nutrients.

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.
