1. Producers (Trophic Level 1)
- What They Are: Plants and phytoplankton that make their own food through photosynthesis.
- Energy Source: They convert sunlight into chemical energy, forming the base of the food web.
2. Primary Consumers (Trophic Level 2)
- What They Are: Herbivores that eat producers, such as insects, small mammals (like monkeys), and fruit-eating birds.
- Energy Transfer: They receive about 10% of the energy from the plants they consume.
3. Secondary Consumers (Trophic Level 3)
- What They Are: Carnivores and omnivores that eat primary consumers, including snakes and small cats.
- Energy Transfer: They get about 10% of the energy from the herbivores they prey upon.
4. Tertiary Consumers (Trophic Level 4)
- What They Are: Apex predators that feed on secondary consumers, like jaguars and large birds of prey.
- Energy Transfer: They receive a smaller amount of energy than the levels below them due to the energy transfer rule.
5. Decomposers (Not in Pyramid but Important)
- What They Are: Organisms like fungi and bacteria that break down dead material.
- Role: They recycle nutrients back into the ecosystem, helping producers grow.
