Right now in class we are learning about how organisms get their food and what their role is in the ecosystem. organisms can either be producers, consumers or decomposers. Here is some information on them:
Some organisms, like trees and almost all types of plants, can make their own food and they are called producers. Producers use a source of energy, like sunlight, to make their own food. Producers are at the bottom of the food chain and they are the source of all food in an ecosystem.
Consumers- Consumers are organisms who get their food directly or indirectly from producers. Because they can't make their own food they rely on producers for food and energy. There are three different types of consumers. The three types are:
Herbivores- organisms who only eat plants. Some examples are grasshoppers and rabbits.
Carnivores- organisms that only eat other animals. Some examples are spiders and snakes.
Omnivores- organisms eat both plants and animals. Some examples are bears and humans.
Decomposers- After animals die, organisms called decomposers eat their dead matter. Decomposers, such as as molds and mushrooms, are very important to the ecosystems because they get rid of animals' dead bodies. They also return the important materials of the dead animals back to the soil and water.
