Question 2
Biodegradable substances affect the environment in the following ways:

$\to$ The biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance the soil fertility.

$\to$ The biodegradable substances mainly contain carbon. These substances after decomposition release that carbon back into the atmosphere. The influx of carbon into the atmosphere and its corresponding oxide formation amplifies global warming hence brings in undesirable climatic change.
