Ecosystems and Biodiversity
What Makes an Ecosystem?
An ecosystem is a community of living things (plants, animals, and microbes) interacting with each other and with their non-living environment (like sunlight, water, air, and soil). These interactions create complex webs of life, where every organism plays a role.
Why Is Biodiversity Important?
Biodiversity means the variety of life in an ecosystem. More biodiversity often means a healthier and more stable environment. It helps ecosystems recover from disasters, adapt to changes, and provide resources like food, medicine, and clean air.
Types of Ecosystems
- Forests: Home to millions of species, forests store carbon and regulate climate.
- Oceans: Oceans cover most of Earth and are a source of oxygen and food.
- Grasslands: These provide habitats for grazing animals and support agriculture.
Threats to Ecosystems
Human activities like deforestation, pollution, and urbanization can harm ecosystems and reduce biodiversity.
Key Takeaways
- All parts of an ecosystem are connected.
- Biodiversity keeps nature balanced and resilient.
Examples
A rainforest teeming with plants, insects, birds, and mammals.
A coral reef supporting thousands of marine species.
In a Nutshell
Ecosystems are communities of living and non-living things, and biodiversity keeps them healthy and strong.
