Food Webs in Nature
Food Webs
Food Webs are Food Chains that
intersect each other. Food webs
are what really happens in nature.
All Food Chains and Webs start
with the sun. The sun is the source
of all the energy on the earth.
Plants are producers. They turn
energy from the sun into sugars
that animals can use.
Insects and other animals eat
plants for energy. They are primary
consumers. They are herbivores.
Secondary consumers are animals
that eat other animals for energy.
They are called carnivores.
Decomposers are organisms that
eat dead things for energy.
Summary
•
Combined food chains make food webs.
•
Food webs start with the sun
•
Food webs contain producers, consumers,
and decomposers.
•
We are part of the food web, too!

Food webs represent the interconnected relationships among organisms in nature, starting with the sun as the primary energy source. Plants act as producers by converting sunlight into sugars, which are consumed by herbivores like insects. Secondary consumers, such as carnivores, then prey on these herbivores. Decomposers play a crucial role in breaking down dead organisms. Overall, combined food chains form intricate food webs that sustain diverse ecosystems, showcasing the balance of nature's energy flow.
