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, with producers at the base and top consumers at the apex.

Front

Which level of the energy pyramid contains the most energy?

Back

Producers contain the most energy in an energy pyramid.

What is a food chain?

Back

A food chain is a linear sequence of organisms where each organism is eaten by the next, illustrating the flow of energy and nutrients.

Front

What role do producers play in a food web?

Back

Producers convert solar energy into chemical energy through photosynthesis, forming the base of the food web.

Front

What is the primary source of energy for most ecosystems?

Back

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

Front

What is a trophic level?

Back

A trophic level is a step in the transfer of energy and matter in a food chain, representing different levels of organisms.

Front

What are tertiary consumers?

Back

Tertiary consumers are organisms that eat secondary consumers and are typically at the top of the food chain.

Front

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

Back

A food chain is a simple linear sequence of energy transfer, while a food web is a complex network of interconnected food chains.

Front

What is the role of decomposers in an ecosystem?

Back

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

Front

How does energy flow in an ecosystem?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and finally to tertiary consumers, with energy decreasing at each level.
