Biodegradable

Imagine you have a piece of paper and when you no longer have use for it you throw it away. If the paper is biodegradable it will break down or decompose over time naturally and sometimes relatively quickly without causing harm to the environment. In other words, it can be broken down by natural organisms, such as bacteria or fungi, it will then eventually be absorbed by nature. Not all materials are biodegradable or can be easily broken down by natural processes.
