This section of ecology focuses on the movement of energy through an ecosystem and the recycling of matter. In most cases, the energy for an ecosystem starts with the sun. Producers use this energy to make food using the process of photosynthesis. Consumers then eat producers, or other consumers, to get the energy they need. There are several types of consumers...herbivores, carnivores, omnivores, scavengers and decomposers. The decomposers break down waste and return nutrients to the soil.
Matter is recycled in an ecosystem. We will be learning about the water cycle, carbon cycle, nitrogen cycle and phosphorus cycle.
