Food Chains, Energy Pyramids and Carbon Cycle

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem, starting from producers to various levels of consumers.

Front

What role do producers play in a food chain?

Back

Producers, such as plants, create their own food through photosynthesis and form the base of the food chain.

Front

What is a primary consumer?

Back

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

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers (herbivores) for energy.

Front

What is a decomposer?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead organic matter, returning nutrients to the soil.

Front

How does energy flow in a food chain?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and so on, with each level receiving less energy than the one before.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the amount of energy available at each trophic level in a food chain.

Front

Why are there fewer top predators in a food chain?

Back

There are fewer top predators because they require more energy and resources, which are limited as you move up the food chain.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen.
