in wat ways do biodegradable wastes affect the environment?

Answer 1

Among other ways:
1. They may add to the nutrients available in the ecosystem, such as when apple cores or potato peels are broken down by decomposers.
2. They may take a very long time to break down, so they aren't much different than other litter in that case. Or they may be discarded in such a way that they do not decompose. An example is a load of tightly compacted, stacked newspapers buried in a landfill. Newspapers are still readable decades later because they don't spread apart to allow air, moisture, and microorganisms to get to the paper.
3. They may add too many nutrients to aquatic ecosystems, causing a chain reaction known as eutrophication. This doesn't turn out well for the ecosystem.

Answer 2

They are good for the environment whereas non-biodegradable cannot be broken down into simpler substances and will harm the environment
