Paragraph based question Read the following paragraphs and answer the questions based on it. After the death of apex consumers, their energy becomes available to the decomposers. Fungi and other micro-organisms decompose the bodies of dead animals. They are called decomposers. In the process of obtaining food from the remains of organisms, decomposers convert them into simple carbon compounds. These substances easily mix with air, water and soil from where they are again absorbed by plants and incorporated into the food chain. How is energy supplied to decomposers?
