Ecosystem Organisation Levels

Describe the hierarchical levels of organization in an ecosystem, from individual organisms to the entire ecosystem.

Define an ecosystem as the combination of all living organisms in a specific environment interacting with non-living components like soil, air, and water.

Define a habitat as the specific location where an organism lives within an ecosystem.

Define a population as all the individuals of the same species living together in a habitat.

Define a community as all the populations of different organisms coexisting in the same habitat.

Understand how feeding relationships within a community can be accurately represented using food chains.

Identify that all food chains begin with a producer, usually a green plant that synthesizes molecules like glucose by absorbing light.

Use food webs to analyze the interdependence of various species within an ecosystem regarding their food sources.

Categorize organisms within a food web as producers, primary consumers, secondary consumers, or tertiary consumers.

Define predators as consumers that kill and eat other animals, and prey as the animals being eaten.

Explain the cyclical rise and fall of predator and prey populations within a biological community.
