Match the items in Column A with the items in Column B. Column A Column B 1. Dodder ( Cuscuta ) (a) Saprophytes 2. Lichen (b) Insectivorous 3. Indian pipe (c) Autotrophs 4. Venus flytrap (d) Bacteria 5. Green plants (e) Symbiosis (f) Parasite

1- (f) Plants or animals which live in (or on) other living organisms and derive their food from them are called parasites . Dodder is an example. It has haustoria for the absorption of food from the host plant. 2- (e) The interaction between two organisms in which both partners get benefited from each other is called symbiosis or mutualism. Lichen is a typical example of symbiosis because of the mutual relationship between an alga and a fungus. The fungus absorbs water and minerals to share with the alga whereas the alga supplies organic food to the fungus. 3- (a) Plants that live and feed on dead or decaying organic matter are called saprophytes. Since Indian pipe derives food from dead or decaying matter, it is a saprophyte . Saprophytes are mostly fungus and/or bacteria. 4- (b) Plants that derive their nutrients by trapping and consuming insects are known as insectivorous plants. Venus flytrap is an example. 5- (c) Autotrophs are organisms that can prepare their food from simple inorganic substances. Green plants are examples as they prepare their food through the process of photosynthesis. Column A Column B 1. Dodder ( Cuscuta ) (f) Parasite 2. Lichen (e) Symbiosis 3.
