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. |
