Energy Cycles
Energy
| Term | Definition |
|---|---|
| Autotroph | energy that makes their own food (ex:plants,photosynthesis) |
| Primary consumers | consumer that feeds directly on producers |
| Omnivores | consumer that eats both producers and consumers |
| Detritus | wastes and remains of dead organisms |
| Photosynthesis | process by which plants use the sun's energy to convert water and carbon dioxide into sugars |
| Consumer | organism that obtains food by eating producers (autotrophs) or other consumers |
| Secondary Consumers | consumer that eats primary consumers |
| Decomposers | Organism that breaks down wastes and dead organisms |
| Food Webs | pattern of feeding in an ecosystem consisting of interconnected and branching food chains |
| Producers | organism that makes its own food (autotroph) and produces organic molecules that serve as food for other organisms in its ecosystem |
| Heterotroph | organism that obtains food by eating other organisms |
| Carnivores | consumer that eats only other consumers ( |
| Trophic Levels | feeding level in an ecosystem |
| Food Chain | pathway of food transfer from one trophic level to another |
| Herbivores | consumer that eats only producers |
| Tertiary consumers | consumer that eats secondary consumers |
| Cellular respiration | chemical process that uses oxygen to convert chemical energy stored in organic molecules into ATP |
| Primary Productivity | rate at which producers in an ecosystem build biomass |
| energy Pyramid | diagram representing energy loss from one trophic level to the nex |
| Biomass pyramid | diagram representing the biomass in each trophic level of an ecosystem |
| Pyramid of numbers | representation of the number of individual organisms in each trophic level of an ecosystem |
| Chloroplast | organelle found in some plant cells and certain unicellular organisms where photosynthesis takes place |
| Chlorophyll | pigment that gives a chloroplast its green color; uses light energy to split water molecules during photosynthesis |
| Stroma | thick fluid contained in the inner membrane of a chloroplast |
| Thylakoid | disk-shaped sac in the stroma of a chloroplast; site of the light reactions of photosynthesis |
| Light reactions | chemical reactions that convert the sun's energy to chemical energy; take place in the membranes of thylakoids in the chloroplast |
| Calvin cycle | cycle in plants that makes sugar from carbon dioxide, H+ ions, and high-energy electrons carried by NADPH |
