Match the following: Column A Column B 1. Cuscuta (Amarbel) a. saprotrophs 2. Animals b. parasitic plant 3. Pitcher plant c. heterotrophs 4. Fungi d. insectivorous plant 5. Lichen e. symbiotic relationship

1-b. Some plants lack chlorophyll, and they can not prepare their own food, so they climb on other plants known as host to obtain their nutrition, this mode of nutrition is called the parasitic mode of nutrition. The plant which feeds in the host is known as a parasite. For example- Cuscuta. 2-c. Organisms which can not prepare their own food and depend on others for their food are called as heterotrophs and this mode of nutrition is called heterotrophic mode of nutrition. For example- animals. 3-d. Some plants feed on other insects to fulfil their nutritional requirement. Such heterotrophic plants are called as insectivorous plants. For example- Pitcher plant. 4-a. Organisms which feeds on dead and decaying matter to obtain their nutrition are called saprotrophs and this mode of nutrition is called saprotrophic mode of nutrition. For example- Fungi. 5-e. The relationship where two organisms live together for mutual benefit is called symbiotic relationship. Lichen is a symbiotic association between a fungi and algae. Column A Column B 1. Cuscuta (Amarbel) b. parasitic plant 2. Animals c. heterotrophs 3. Pitcher plant d. insectivorous plant 4. Fungi a. saprotrophs 5. Lichen e. symbiotic relationship
