Match the items given in Column I with those in Column II. Column I Column II 1. Chlorophyll (i) Rhizobium 2. Nitrogen (ii) Heterotrophs 3. Cuscuta (iii) Pitcher plant 4. Animals (iv) Leaf 5. Insects (v) Parasite

1-(iv) Chlorophyll is a photosynthetic pigment present on leaves. It absorbs solar energy and uses it for the synthesis of carbohydrates with the help of carbon dioxide and water. 2-(i) Rhizobium is a symbiotic bacterium that is present in the root nodules of leguminous plants that help to absorb atmospheric nitrogen. 3-(v) Cuscuta is an example of a parasitic plant. It does not have chlorophyll. It takes readymade food from the plant on which it is climbing. 4-(ii) Animals and most other organisms take food prepared by plants. They are called heterotrophs. 5-(iii) The pitcher plant is an example of an insectivorous plant. They are partially autotroph and partially heterotroph. Column I Column II 1. Chlorophyll (iv) Leaf 2.

The green pigment present in plants is known as chlorophyll. During photosynthesis, it captures energy from the sunlight and uses it to prepare food from carbon dioxide and water. This pigment is also present in algae which makes them perform photosynthesis.
