Food Chains and Food Webs

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.

What role do decomposers play in a food web?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers, thus playing a crucial role in nutrient cycling.

Front

What are producers in a food chain?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and serve as the base of the food chain.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy. They can be herbivores, carnivores, or omnivores.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores are animals that eat only plants, while carnivores are animals that eat only other animals.

Front

What are omnivores?

Back

Omnivores are animals that eat both plants and animals.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that shows how different organisms in an ecosystem are related through feeding relationships.

Front

Where does the energy in a food chain originate?

Back

The energy in a food chain originates from the sun, which is captured by producers through photosynthesis.

Front

What is the role of the sun in a food chain?

Back

The sun provides the energy necessary for plants (producers) to grow, which is then passed on to consumers in the food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients, such as producers, primary consumers, and secondary consumers.
