Study Notes

What is an Ecosystem?

An ecosystem is a community of living and non-living things that interact with each other in a specific environment.

Classifications of Ecosystems

Ecosystems can be divided into two basic categories: terrestrial and aquatic.

Terrestrial Ecosystems

Examples include forests, grasslands, deserts, and tundra.

Aquatic Ecosystems

Examples include freshwater ecosystems like rivers, lakes, and wetlands, as well as marine ecosystems like coral reefs and estuaries.

The Biosphere

The entire biosphere is regarded by many ecologists as a single, large ecosystem that encompasses all ecosystems on Earth.
The biosphere is considered a global ecosystem that includes all living organisms and their environments.
To study the biosphere, ecologists categorize it into smaller ecosystems, such as terrestrial and aquatic ecosystems.

Man-made Ecosystems

An example of a man-made ecosystem is a farm.

Studying Ecosystem Structure

When studying the structure of an ecosystem, the primary focus is on the relationships between living organisms and their physical environment.

The Biosphere Perspective

Ecologists consider the entire biosphere to be a complex system that is made up of many interconnected ecosystems.
