In just a few words, describe an ecosystem
"Identify the four major components of Earth's life support system
Identify the three factors that sustain life on Earth. "
An ecosystem is a network of living organisms that interact with each other and their environment. These interactions create an intricate balance of energy and matter in the environment. Ecosystems play an important role in regulating the environment and providing resources to people.
Ecosystems: A Look at Nature's Balance
Ecosystem: A biological system consisting of all the living organisms in a specific environment and their interactions with each other and their environment. Biodiversity: The variety of life found within a particular ecosystem, which includes the different plants, animals, and microorganisms that live in the environment. Ecological Niche: The specific role and position a species occupies in an ecosystem, including factors such as its food sources, its predators, and its environmental conditions.
The average temperature of an ecosystem is crucial for the life of its organisms; a change of even 1 degree Celsius can have a significant effect. The term 'ecosystem' was first used by the British biologist Arthur Tansley in 1935. The term 'biotic' is used to refer to the living elements of an ecosystem, such as plants, animals, and bacteria.
