4.5b Food Webs

This Food Web show a much better representation of the full community in an ecosystem.

A food web  shows animals feeding at different trophic levels

meaning that an animal can have

• Multiple predators
• Multiple prey
• Links with other food chains

In the web the producer (grass) is coloured Green, the Primary consumers are Red and the Secondary consumers are Blue.

But the Hawk and the Fox are both secondary and tertiary consumers:

Because, the hawk eats rabbit, a primary consumer, making the Hawk a Secondary consumer, but also feasts on small birds which are secondary consumers themselves, so the hawk is acting at the tertiary consumer level in this case.
