Detailed explanation-1: -Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers-plants or algae-and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
Detailed explanation-2: -The mouse and the hawk are at the third and fourth levels of the food chain example. Like the grasshopper, they are consumers. However, the mouse and the hawk are consumers called carnivores because they eat other animals.
Detailed explanation-3: -Basically, food web represents feeding relationships within a community (Smith and Smith 2009). It also implies the transfer of food energy from its source in plants through herbivores to carnivores (Krebs 2009). Normally, food webs consist of a number of food chains meshed together.
