The length and complexity of food chains vary greatly. Each organism is generally eaten by two or more other kinds of organisms which in turn are eaten by several other organisms. So, instead of a straight-line food chain, the relationship can be shown as a series of branching lines called a food web. i. The greatest number in trophic levels of food chain is of: a) Producers b) Primary consumers c) Secondary consumers d) Tertiary consumersii. Green plants in a terrestrial ecosystem capture ..... of the energy of sunlight that falls on their leaves and convert it into food energy. a) 1% b) 5% c) 10% d) None iii. Biological magnification is greatest in: a) Plants b) Lion c) Humans d) Micro-organisms iv. Decomposers comprises of: a) Bacteriab) Fungi c) Earthworms d) All v. Flow of energy in food web is unidirectional. This implies: a) 1% law b) 5% lawc) 10% law d) None
