What is 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 is a community in ecological terms?

Back

A community is a collection of different populations of organisms that live in the same area and interact with one another.

Front

What is a trophic level?

Back

A trophic level is each level represented within a food chain, indicating the position of an organism in the flow of energy.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is the sun.

Front

How much energy is typically transferred from producers to primary consumers?

Back

Typically, about 10% of the energy is transferred from producers to primary consumers.

Front

What is the role of producers in an ecosystem?

Back

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

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which energy and nutrients flow, while a food web is a complex network of interconnected food chains.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are typically herbivores.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

Front

What is energy flow in an ecosystem?

Back

Energy flow in an ecosystem refers to the transfer of energy from one trophic level to another, starting from producers to various levels of consumers.
