Ecosystem service is like the services you get from a business. Things like cleaning, haircuts, and house repairs are services businesses provide to us. Ecosystems provide us with services, too. An ecosystem is a group of living things (plants, animals, and other living organisms) that depend on each other to survive in an environment. Even if you don't see them with your eyes, ecosystems provide us with services that help us humans live.
Ecosystem services can be described as the natural things that ecosystems provide for us. These include things like clean air, drinking water, and food. Other ecosystem services include things like pollination, pest control, and other natural resources that humans need. All of these things help us have clean water to drink, food to eat, good air to breathe, and materials for building things.
Even though ecosystems provide these services for us, sometimes these services get damaged or destroyed. That's why it's important for us to take care of our environment and ecosystems so that they can continue to provide us with the services we need.
