Explanation:
Detailed explanation-1: -Amazing Facts. A parasite is an organism that cannot live on its own and requires another organism, a host, to provide it with the essentials of life. It is estimated that up to 80 percent of living organisms are parasites! That means we all have a lot of other organisms to nurture.
Detailed explanation-2: -Without a host, a parasite cannot live, grow, and multiply. For this reason, a parasite rarely kills its host, but it can spread diseases, some of which may be fatal.
Detailed explanation-3: -Some rare parasites are called facultative, because they can survive and reproduce without a host, but very few that infect humans belong to this group (e.g. free-living amoebae).
