Energy Transfer
1. All living things get and use energy.
2. Organisms use the energy to grow and reproduce.
3. The sun supplies the energy for almost every ecosystem on Earth.
4. Plants make their own food with CO2, H2O, and energy from the sun. Plants are called producers because they make their own food. Plants store unused energy in their roots, stems, and leaves.
5. All other organisms, except for plants, must eat to get energy. They are called consumers.
6. Plants are the beginning of the food chain. The food chain is how the energy is passed through the communities.
7. Herbivores are the organisms that eat plants.
8. Carnivores are the organisms that eat herbivores.
9. Omnivores are the organisms that eat the producers, herbivores, and carnivores. They are usually the top predator.
10. Decomposers are the bacteria that eat anything that was alive and return the nutrients to the soil.
