Give any two ways in which biodegradable substances would affect the environment.
Ans: Two ways in which biodegradable substances can affect the environment are:
Nutrient Cycling: Biodegradable substances, when decomposed by microorganisms, contribute to the recycling of nutrients in ecosystems. This nutrient cycling helps maintain the fertility of the soil, promotes plant growth, and supports the overall health and functioning of ecosystems.
Soil Improvement: Biodegradable substances, such as organic waste or compost, can be used to improve soil quality. When added to the soil, these substances enhance its structure, water-holding capacity, and nutrient content. They promote the growth of beneficial microorganisms, improve soil fertility, and support sustainable agricultural practices.

Recycling: Recycling involves collecting and processing waste materials to create new products. By participating in recycling programs, you can ensure that materials such as paper, plastic, glass, and metals are diverted from landfills and undergo processes to be transformed into new usable items. Separating recyclable waste from non-recyclable waste and supporting recycling initiatives helps conserve resources, reduce energy consumption, and decrease the amount of waste that ends up in landfills.
Composting: Composting is a natural process that decomposes organic waste, such as food scraps, yard trimmings, and other biodegradable materials, into nutrient-rich compost. By composting these materials instead of disposing of them as waste, you can produce a valuable soil amendment that enriches the soil and reduces the need for chemical fertilizers. Composting can be done at home or through community composting programs, contributing to waste reduction and promoting sustainable gardening practices.
