Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to top-level consumers.

Front

What limits the number of levels in an energy pyramid?

Back

The number of levels in an energy pyramid is most likely limited by energy loss between each level of organisms, as energy is lost as heat and through metabolic processes.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, temperature, soil, and water, that influence the living organisms within that environment.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are the living components of an ecosystem (like plants and animals), while abiotic factors are the non-living components (like water, soil, and climate).

Front

What is a population in ecological terms?

Back

A population is a group of individuals of the same species that live in a specific area and interact with one another.

Front

What is a community in ecology?

Back

A community is a group of different populations that live together in a defined area and interact with each other.

Front

What is an ecosystem?

Back

An ecosystem is a biological community of interacting organisms and their physical environment, including both biotic and abiotic factors.

Front

What is a biome?

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as a desert or rainforest.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and algae.

Front

What are trophic levels?

Back

Trophic levels are the hierarchical levels in an ecosystem, defined by how energy and nutrients flow through the food chain, including producers, primary consumers, secondary consumers, and tertiary consumers.
