Answer:
Food webs are models to show how organisms are related in an ecosystem based on how they get their energy. The main roles are producers, consumers, and decomposers?
Step-by-step explanation:
Producers
Producers make their own energy through photosynthesis. All most all plants, But not all, are Producers.
Consumers can be divided into
- Primary > Primary consumers get energy by eating producers. They are usually small animals, insects and herbivores.
- Secondary > Secondary consumers get energy eating primary consumers. Secondary consumers are usually predators.
- Tertiary > Tertiary consumers get energy by eating secondary consumers. Owls and birds of prey, bears and large predator's, and carnivores are usually tertiary consumers. Humans are also among the tertiary consumers.
And lastly Decomposers
Decomposers get by breaking down dead organisms and returning nutrients to the soil. Decomposers are usually fungi-like-mushrooms and bacteria
