Key Stage 3
Meaning
A food web is a diagram made from many food chains linked together.
About Food Webs
- Food webs always start with a producer.
- The arrows in a food web always point from the food to the animal that eats it.
Examples
These two food chains can be combined into a food web.
 |
| This a food chain. |
 |
| This a food chain. |
 |
| This food web has been made by combining the two food chains. |
 |
| This food web has trees, grass and bushes as producers at the bottom and Lions and Vultures as the top carnivores. |
 |
| This food web has seaweed and phytoplankton as producers at the bottom and Blue Whales and Killer Whales as the top carnivores. |
Key Stage 4
Meaning
A food web is a diagram which shows the feeding relationship between many organisms in a community.
About Food Webs
- Food webs always begin with the first trophic level (a producer).
- The arrows in a food web always show the direction of energy transfer between the trophic levels.
|
| This a food web shows the feeding relationships between organisms in a community that live in a savanna habitat. |
|
| This a food web shows the feeding relationship between organisms in a community that live in the Southern Ocean and Antarctica which is both an arctic and an ocean habitat. |
