Energy Pyramid | A diagram that shows the trophic levels of organisms in a food web. |
Producers | Organisms that make complex, energy-containing biomolecules from simple inorganic molecules using energy captured from light or inorganic chemical compounds. |
Consumers | An organism that must consume other organisms for nutrients. |
Tertiary Consumers | Animals that eat secondary consumers. |
Herbivores | Organisms that consume only plants. |
Carnivores | Animals that eat other animals. |
Decomposers | Organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion. |
Food Chain | A single, linear path showing the flow of energy from the sun to producer and through different levels of consumers. |
Food Web | Overlapping food chains with different pathways for the flow of food energy in an ecosystem. |
Grazing Food Web | Starts with radiant energy captured by producers through photosynthesis, and continues with energy flow from producers to consumers and finally to decomposers. |
Detrital Food Web | Starts with chemical energy stored in organic debris or waste from other food webs; continues flowing energy directly to decomposers. They become food and energy for consumers, and again, decomposers. |
Primary Consumers | An organism that gets their energy by feeding on producers in the food chain. |
Secondary Consumers | Animals that eat other animals that eat plants. |
Trophic Level | The position an organism occupies on the food web. |
