Any two ways in which non-biodegradable substances may affect the environment are: 1. The main problem caused is pollution. Non-biodegradble substances take many decades to degrade and hence remain in the environment causing pollution. 2. They may render the soil infertile and hence affect the vegetation.

Question 1. What are the trophic levels? Give an example of a food chain and state the different trophic levels in it. Answer: Each step or level of a food chain is called Trophic levels. Example for Food chain Here grass is a producer because it prepares its own food. This grass is eaten by herbivores means secondary, small carnivores (Frog) are tertiary and higher carnivores are in the fourth level. Question 2. What is the role of decomposers in the ecosystem? Answer: Microorganisms, comprising bacteria and Fungi, break-down the dead remains and waste products of organisms. These microorganisms are the decomposers as they break-down the complex organic substances into simple inorganic substances that go into the soil and are used up once more by the plants. Text Book Part I Page No. 142 Question 1. Why are some substances biodegradable and some non-biodegradable? Answer: Substances that are broken down by biological processes are said to be biodegradable. Eg: paper and peel of a fruit. But plastic leather etc. are not broken down. These are called Non-biodegradable. Question 2. Give any two ways in which biodegradable substances would affect the environment. Answer: • Leaves of the plants decay and reduces soil fertility, • Bio-degradable substances have carbon. When this is burnt, CO 2 and CO are produced and causes air pollution. Question 3. Give any two ways in which non-biodegradable substances would affect the environment. Answer: • As these are not decomposing, the...

Effects of non-biodegradable substances on the environment: • The non-biodegradable substances remain in the non-degraded form for a long time in the environment and thus cause pollution. • They can enter the food chain in different ways. For example, they can enter the plant tissue through the soil or contaminated water. • The presence of these substances can affect the physical en...
