When does biodegradation occur?
Biodegradation occurs when microorganisms degrade or break down, organic matter into inorganic substances that can be used by other organisms or recycled through Earth's systems. The rate at which materials are degraded depends upon the type of material and conditions such as moisture, sunlight, and heat.
What is biodegradable?
Most organic renewable resources such as plants, animals, and related products and wastes are biodegradable. (Organic resources are those that are, or come from, living things.)
Why are they called Fossil Fuels?
Fossil Fuels are called so because they formed from the buried remains of ancient plants and animals over millions of years. (The dinosaur in the picture looks like it's doing the shocked "oop" sound)
