Ecosystems

What Makes up an Ecosystem? Organism: any living thing. Populations: a collection of organisms of a given species. Communities: all the different populations of organisms in a specific area or region at a certain time.

What Is an Ecosystem? Ecosystems vary in size. They can be as small as a puddle or as large as the Earth itself. Any group of living and nonliving things interacting with each other can be considered as an ecosystem. Organisms in a petri dish Organisms in the world

What about Biomes? A large community classified by the climate, vegetation, and the different adaptations of organisms. Are composed of biotic and abiotic components.

Abiotic and Biotic Factors All the living things in an ecosystem Such as plants, animals, fungi and bacteria. Abiotic Factors All of the nonliving things that affect an ecosystem. Water, sunlight, oxygen, temperature and soil.

An example of an ecosystem is a BIOME! The Tundra The Taiga The Desert The Ocean A Pond A Estuary A Tropical Rain Forest
