* Producers: Organisms like plants, algae, and some bacteria are called producers. They use sunlight, water, and carbon dioxide to produce their own food through photosynthesis. This process stores energy from the sun in chemical bonds of sugar molecules.
* Consumers: Animals, fungi, and many bacteria are consumers. They cannot make their own food and rely on eating other organisms to get energy.
* Herbivores: Eat only plants.
* Carnivores: Eat other animals.
* Omnivores: Eat both plants and animals.
* Decomposers: Break down dead organisms and waste products, releasing nutrients back into the environment.
Here's the key takeaway:
* Producers directly capture energy from the sun.
* Consumers indirectly obtain energy by consuming producers or other consumers.
This flow of energy from the sun to producers to consumers is a fundamental principle of ecosystems and is represented by the food chain and food web concepts.
