* Producers: Plants, algae, and some bacteria are called producers. They use sunlight through photosynthesis to convert carbon dioxide and water into sugars (glucose), which they use for energy and growth. This process also releases oxygen into the atmosphere.
* Consumers: Animals, including humans, are consumers. They obtain their energy by eating producers (herbivores) or other consumers (carnivores).
* Decomposers: Organisms like fungi and bacteria break down dead plants and animals, releasing nutrients back into the environment for producers to use.
Energy Flow: Energy flows through an ecosystem in a one-way direction:
1. Sun: The sun provides the initial energy input.
2. Producers: Producers capture sunlight and convert it into chemical energy.
3. Consumers: Consumers eat producers or other consumers, gaining energy from the chemical bonds in their food.
4. Decomposers: Decomposers break down dead organisms, releasing nutrients back into the environment.
Important Note: Energy is lost at each step in the food chain. This is why there are fewer top predators than primary consumers in an ecosystem.
