Energy Cycles
| Term | Definition |
|---|---|
| Energy | the strength and vitality required for sustained physical or mental activity |
| Autotroph | An organism capable of synthesizing its own food |
| Primary Consumers | herbivore |
| Omnivores | an animal or person that eats food of both plant and animal origin |
| Detritus | waste or debris of any kind |
| Photosynthesis | process by which green plants and some other organisms use sunlight to synthesize foods |
| Consumer | An organism that cannot synthesize its own food |
| Secondary Consumers | carnivore |
| Decomposers | an organism, esp. a soil bacterium, fungus, or invertebrate, that decomposes organic material |
| Food Webs | system of interlocking and interdependent food chains |
| Producers | anything that can make its own food, like plants |
| Heterotroph | consumer which must take food from other plants |
| Carnivores | an animal that eats a diet consisting mainly of meat |
| Trophic level | group of organisms that occupy the same position in a food chain |
| Food Chain | series of organisms showing feeding relationships |
| Biomass | weight or total quantity of living organisms of one animal or plant species |
| Herbivores | an animal that gets its energy from eating plants |
| Tertiary Consumers | an animal that eats only other carnivores |
| Cellular Respiration | process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP |
| Primary Productivity | plants and other photosynthetic organisms produce organic compounds in an ecosystem. |
| Energy Pyramid | diagram that shows the transition of energy from one trophic level to another |
| Biomass Pyramid | graphical representation to show the biomass or biomass productivity at each trophic level |
| Pyramid of Numbers | graphical representation of the numbers of individuals in each population in a food chain |
| Kinetic Energy | energy that a body possesses by virtue of being in motion |
| Calorie | energy that a body possesses by virtue of being in motion |
| Potential Energy | energy that something has because of its position or the way its parts are arranged |
| ATP | (Adenosine triphosphate) is the only useable form of energy in the body |
| Thermal Energy | form of energy that is created by heat, or an increase in temperature |
| Chemical Energy | part of the energy in a substance that can be released by a chemical reaction |
| Chloroplast | organelles found in plant cells and eukaryotic algae that conduct photosynthesis |
| Thylakoid | carry out the light reactions of photosynthesis |
| Photosynthesis | process of converting light energy to chemical energy and storing it in the bonds of sugar |
| Light Reactions | first stage of photosynthesis |
| Chlorphyll | molecule,absorbs sunlight & uses its energy to synthesise carbohydrates from CO2 and water |
| Calvin Cycle | pathway found in stroma of the chloroplast in which carbon enters in form of CO2 & leaves in form of sugar |
| Stroma | spongy, colorless matrix of a cell that functionally supports the cell |
