What is a Food Web?

A Food Web is a complex network of many interconnected food chains and feeding interactions.

Both the river and the wetland have complex microscopic food webs which contain producers (bacteria and microalgae), herbivores, predators and detritivores, which eat plant litter and dead organisms. When these get bigger and more visible at 1-2mm they are described as macroinvertebrates which include again worms, crustaceans, mollusks and insects in the freshwater system. These become part if the diet of many of the species if fish, reptiles, amphibians, birds, mammals and humans.

Generally animals eat things that are smaller than themselves.
Herbivoreseat vegetable matter.
 Carnivores eat other animals.
Omnivores eat both vegetable matter and other animals.

In the Estuary environment there are some animals known as filter feeders that filter their food out of the water
that feed on the remains of dead animals within the system.
