Organic material

Organic material is stuff made of living things or that used to be alive. Think of a plant, a tree, or even your pet cat. All of these things are organic materials because they were once living things.
When something is organic, it means it was made by nature and not humans.
Organic material can be found in different forms. It can be in the form of compost (a mixture of decaying plant and animal matter), mulch (a protective layer made of dead leaves and bark) or even in the food we eat (fruits, vegetables, and meat).
It’s important to take care of organic materials because they can break down and decompose and turn into soil which can help plants grow healthy and strong. That’s why we often hear about “composting” which is when we mix organic materials like food scraps, leaves, and grass clippings into a special bin, and over time they turn into nutrient-rich soil.
Overall, organic material is an important part of nature and helps keep our environment healthy and happy.
