| Term | Definition |
|---|---|
| Energy | the capacity for vigorous activity; available power |
| Autotroph | any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists. |
| Primary consumers | an animal that feeds on plants; a herbivore. |
| Omnivores | an animal that eats meat and plants. |
| detritus | rock in small particles or other material worn or broken away from a mass, as by the action of water or glacial ice. |
| Photosynthesis | the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll. |
| Consumer | a person or thing that consumes. |
| Secondary consumers | a carnivore that feeds only upon herbivores. |
| Decomposers | an organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances. |
| Food Webs | a series of organisms related by predator-prey and consumer-resource interactions; the entirety of interrelated food chains in an ecological community. |
| Producers | The first trophic level in a food chain in which it serves as a food source for consumers or for higher trophic levels. |
| Heterotroph | an organism requiring organic compounds for its principal source of food. |
| Carnivores | A meat-eating animal. |
| Tropohic level | It is the levels of the food chain/food web. |
| Food Chain | A feeding hierarchy in which organisms in an ecosystem are grouped into trophic levels and are shown in a succession to represent the flow of food energy and the feeding relationships between them. |
| Biomass | The total mass of all living material in a specific area, habitat, or region. |
| Herbivores | animals that eat plants. |
| Tertiary consumers | a carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only on secondary consumers. |
| Cellular respiration | The process of cell catabolism in which cells turn food into usable energy in the form of ATP. |
| Primary Productivity | a measure of the rate at which new organic matter is developed through photosynthesis and chemosynthesis in producer organisms based on the oxygen released and carbon taken in; the transformation of chemical or solar energy to biomass |
| Energy Pyramid | a depiction of the amount of energy in each trophic level of an ecosystem. |
| Biomass Pyramid | A graphical representation to show the relative amounts of biomass at each trophic level. |
| Pyramid of numbers | A graphical representation in the form of a pyramid showing the feeding relationship and the number of organisms at each trophic level. |
| Chrolplast | Chlorophyll-containing plastid found within the cells of plants and other photosynthetic eukaryotes. |
| thylakoid | |
| stroma | |
| Calvin Cycle | |
| photosynthesis | |
| light reactions | |
| chorophyll |
