What is an ecological pyramid?

Back

An ecological pyramid is a graphical representation that shows the relationship between different trophic levels in an ecosystem, illustrating the distribution of biomass, numbers, or energy.

Front

What are the three main types of ecological pyramids?

Back

The three main types of ecological pyramids are: Pyramid of Numbers, Pyramid of Biomass, and Pyramid of Energy.

Front

What does a pyramid of biomass represent?

Back

A pyramid of biomass represents the total mass of living organisms at each trophic level in an ecosystem, typically measured in grams per square meter.

Front

What is a pyramid of numbers?

Back

A pyramid of numbers shows the number of individual organisms at each trophic level in an ecosystem, regardless of their size.

Front

What is a pyramid of energy?

Back

A pyramid of energy illustrates the flow of energy through each trophic level, showing the amount of energy available at each level, usually measured in joules.

Front

Why can a pyramid of biomass be inverted?

Back

A pyramid of biomass can be inverted when the biomass of primary producers (like phytoplankton) is less than that of the consumers (like zooplankton) at a given time.

Front

What is a key advantage of using a pyramid of numbers?

Back

A key advantage of using a pyramid of numbers is that it includes all organisms regardless of their size, providing a straightforward count.

Front

What is a limitation of pyramids of numbers?

Back

A limitation of pyramids of numbers is that they can be misleading if one organism is much larger than others, as it may not accurately represent the ecosystem.

Front

How do pyramids of energy differ from pyramids of biomass?

Back

Pyramids of energy show the flow of energy through trophic levels, while pyramids of biomass show the total mass of organisms at each level.

Front

What does it mean if a pyramid of biomass is upright?

Back

An upright pyramid of biomass indicates that the biomass decreases from the base (producers) to the top (top predators), which is typical in most ecosystems.
