Answer 2

Answer:

1. a large number of plants are unable to produce their own food because of the absence of chlorophyll. These plants, therefore, feed on other plants or dead animals. Plants that feed on other plants are called 'parasites'. Those plants that feed on dead organic matter are called 'saprophytes'.

2. A parasite must remain in close contact with its host. It depends on the host for its food and is unable to live a free life for very long. This is because most parasites have become thoroughly adapted to a parasitic existence.

3. Ectoparasite: A parasite that lives on or in the skin but not within the body. Fleas and lice are ectoparasites. Infestation with an ectoparasite is called an ectoparasitosis
