Food web
definition
A food web shows how plants and animals are interconnected through a variety of different paths and interactions. In other words, it consists of all of the food chains in the ecosystem. Organisms in food webs are divided into trophic levels. Producers make up the first level. They are known as autotrophs, who make their own food and are not dependent on other organisms for nutrition. As for the consumers, they depend on other organisms as their food source. The second trophic level is composed of herbivores. They directly eat the producers. The third trophic level is made up of consumers who eat the herbivores. The fourth trophic level in our ecosystem is formed of the animals who eat the secondary consumers. Finally, the decomposers finish off the web, because they eat the remains of any decayed organisms.
explanation
The autotroph, or producer, in this food web is the berry tree. The heterotrophs, or consumers, are the squirrel, bird, owl, raccoon, and hawk. The hawk is the top predator - it is the secondary/tertiary consumer. The bird and the squirrel are primary consumers. The owl and raccoon are the secondary consumers.
