What is a food pyramid in ecology?

Back

A food pyramid is a graphical representation of the energy flow in an ecosystem, illustrating the levels of producers, consumers, and decomposers, with the amount of energy available at each level.

Front

Which organisms have the least amount of energy available in a food pyramid?

Back

Top predators, such as coyotes, have the least amount of energy available because energy decreases as it moves up the food chain.

Front

What are producers in an energy pyramid?

Back

Producers are organisms, typically plants, that create their own energy through photosynthesis and form the base of the energy pyramid.

Front

Define biodiversity in the context of ecology.

Back

Biodiversity refers to the variety of species within an ecosystem, including the diversity of species, genetic variations, and ecosystems.

Front

What is the smallest level of an ecosystem?

Back

The smallest level of an ecosystem is the organism, which is an individual living entity.

Front

How does energy transfer occur in a food chain?

Back

Energy transfer in a food chain occurs when one organism consumes another, with only a portion of the energy being passed on to the next level.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.

Front

What is the significance of trophic levels in an ecosystem?

Back

Trophic levels represent the different stages in a food chain, indicating the flow of energy and nutrients from producers to various levels of consumers.

Front

Explain the concept of an energy pyramid.

Back

An energy pyramid illustrates the amount of energy available at each trophic level in an ecosystem, showing that energy decreases as it moves up the pyramid.

Front

What is the relationship between biodiversity and ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, as diverse ecosystems are more resilient to changes and disturbances.
