Understanding What an Ecosystem Is
An ecosystem is a community of living things that interact with each other and with the nonliving parts of their environment, like air, water, and soil.
The Parts of an Ecosystem
Living components: Plants, animals, fungi, and microorganisms.
Nonliving components: Sunlight, temperature, rocks, and water.
How Ecosystems Work
Organisms depend on each other for food, shelter, and survival. Energy flows from the sun to plants, then to herbivores, predators, and decomposers.
Types of Ecosystems
Forests, deserts, oceans, grasslands, rivers, wetlands, and tundras are all ecosystems. Each has conditions that support unique forms of life.
Why Ecosystems Matter
Ecosystems clean air and water, recycle nutrients, support food chains, and help regulate climate. They keep natural processes running smoothly.
Human Impact on Ecosystems
Pollution, deforestation, climate change, and habitat destruction can harm ecosystems. Healthy ecosystems are essential for life on Earth.
The Simple Takeaway
An ecosystem is a community of life interacting with its environment. It keeps nature balanced and supports every living organism on the planet.
