Ecology Organization Levels

Front

What is the definition of an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What are the levels of ecological organization from smallest to largest?

Back

The levels of ecological organization are: organism, population, community, ecosystem, biome, and biosphere.

Front

What is a population in ecology?

Back

A population is a group of individuals of the same species living in a specific area at the same time.

Front

What is a community in ecology?

Back

A community is made up of different populations of various species that live together in a specific area.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients circulate within an ecosystem.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is the 10% rule in ecology?

Back

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next level, while the rest is lost as heat or used for life processes.

Front

What happens to energy as it moves up trophic levels?

Back

As energy moves up trophic levels, it decreases due to energy loss through metabolic processes and heat.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy and nutrients.
