What are ecological systems?

An ecological system is like a neighborhood where all the living and non-living things work together to keep everything balanced.

Imagine you're playing in a park. There are trees, birds, squirrels, grass, rocks, water from a nearby pond, everything is part of that big, friendly group working together. That’s an ecological system! It's like the rules of a game: every creature and thing has a role to play.

In a park or any ecological system, some things are alive, like you, the birds, or the grass, and some aren’t, like rocks, water, or air. They all help each other out. For example, trees use sunlight to make food, and squirrels eat nuts from those trees. The ground helps hold water for plants, and that water makes the grass grow so animals can eat it too.

It’s like a big team where everyone has their job, some people bring snacks, others clean up, and some help start the game. That way, everything stays happy and balanced!
