A parasite is an organism that lives in another organism, called the host, and often harms it. It is dependent on its host for survival – it has to be in the host to live, grow and multiply. A parasite cannot live independently.
Although a parasite rarely kills the host, in some cases it can happen. To a certain extent, if a parasite does kill its host it has failed as this means it will need to find a new home. The parasite benefits at the expense of the host – the parasite uses the host to gain strength, and the host loses some strength as a result.
