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 various levels of consumers above.

Front

Which level of the energy pyramid contains plants?

Back

The base level (Level D) of the energy pyramid contains plants, which are primary producers.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down organic compounds from dead organisms and waste, recycling nutrients back into the ecosystem for use by other organisms.

Front

What is a parasitic relationship?

Back

A parasitic relationship is a type of symbiosis where one organism benefits at the expense of another, which is harmed.

Front

What organisms are involved in the carbon cycle?

Back

The carbon cycle involves plants, animals, decomposers (fungi and bacteria), and phytoplankton.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers to obtain energy.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers, often 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 linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains.

Front

What is the significance of producers in an ecosystem?

Back

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