Transcript of Food Chains
What is a food web
Energy transfer is an important aspect of a food web. Energy transfer is the transfer of energy from one organism through another through a food web. Here is the basic format for how energy travels:
Sun --> Producer --> Primary Consumer --> Secondary Consumer --> Tertiary Consumer
Other parts of food webs
The Big Idea
The big idea is that a food chain shows all of the feeding relationships between organisms in an environment, and it shows how energy is transferred from one organism to another. Energy is transferred from the sun to the producer to the primary consumer to the secondary consumer then finally to the tertiary consumer. Other parts of food webs are habitat, ecosystems, limiting factors, and tolerance.

A food web is a model that shows many different feeding relationships between organisms in an environment. Energy transfer is an important aspect of a food web. Energy transfer is the transfer of energy from one organism through another through a food web. All of our energy comes from food, the sun, and photosynthesis. Here are two different examples of food webs.
See how each organism loses energy the farther up it is on the food chain
All of our
An ecosystem is all of the living and nonliving things in an area that interact with each other .
A habitat is the location in which an organism/population lives. Habitats provide the population/organism with shelter, food, and water for them to grow
A limiting factor is an factor that limits the growth or development of a population.
Tolerance is the ability for an organism to withstand certain aboiotic factors.
For example: A drought could limit the number of plants which could limit a population of herbivores/primary consumers such as a population of deer
For example: a den is a fox's habitat or a human's habitat is our houses because our houses provides us with food, shelter, and water for us to grow
For example: humans can tolerate only certain temperatures (we can't survive in 200 degrees or -100 degrees)
For example: an ecosystem could be anything from a puddle to a desert to a rainforest.
We couldn't survive
in these conditions.
