(5.9B) Energy Flow
The student is expected to describe how the flow of energy derived from the Sun, used by producers to create their own food, is transferred through a food chain and food web to consumers and decomposers.
Plants are able to use energy from sunlight to manufacture their own food through photosynthesis. This process, which is critical to all life on Earth, is explored in this section.
Producers are able to convert energy from light or heat into the chemical bonds of food molecules through photosynthesis. Consumers must obtain energy by feeding on producers or other consumers. These energy transfer relationships are the basis of food chains and webs in ecosystems.
