Ecology Organization Levels

Front

What is a producer in an ecosystem?

Back

An organism that uses an outside source of energy, like the sun, to create energy-rich food molecules.

Front

What is the approximate efficiency of energy transfer between trophic levels?

Back

Roughly 10%.

Front

What does the biosphere encompass?

Back

The biosphere contains all ecosystems.

Front

What is a community in ecological terms?

Back

A community is a group of different populations living together in the same place at the same time.

Front

If a hawk eats a mouse that consumed insects with 10,000 kcals of energy, how much energy is transferred to the hawk?

Back

100 kcals.

Front

Define the term 'trophic level'.

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is the difference between a population and a community?

Back

A population is a group of individuals of the same species living in a specific area, while a community includes multiple populations of different species.

Front

Explain the concept of energy pyramids in ecology.

Back

Energy pyramids illustrate the energy flow in an ecosystem, showing the amount of energy at each trophic level.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, stability, and productivity.
