| Term | Definition |
|---|---|
| Energy | the ability to do work. |
| photosynthesis | the chemical process that turns carbon dioxide and water into carbohydrate. |
| producers | they create biomass. |
| biomass | the total organic matter in an ecosystem |
| autotroph | self-feeders |
| consumer | organisms that eat other organisms. |
| hererotroph | organisms that other organisms. |
| Primary consumers | the first level of consumers.(herbivores) |
| secondary consumers | meat eaters or carnivores. |
| carnivores | only eat meat.(Ron) |
| tertiary consumers | they feed on secondary consumers. |
| omnivores | have a diet of both producer and consumer. |
| decomposers | eat the remains of dead organisms. |
| trophic level | feeding levels |
| cellular repiration | chemical process that uses oxygen to convert the chemical energy stored in organic molecules into another form of chemical energy |
| detritus | waste of any kind. |
| food web | shows food connections between organisms. |
| food chain | a group of organisms that that depend on each other for survival. |
| herbivores | organisms that only eat plants |
| primary production | flow of of energy that in the ecosystem form organism to organism. |
| energy pyramid | a showing of the biomass at each tropic level. |
| biomass pyramid | a representation of the a biomass |
| pyramid of numbers | a representation of a diet relations between different animals. |
| kinetic energy | the energy that an object has due to its motion. |
| calorie | amount of energy that is needed to raise the temperature |
| potential energy | energy that is stored in an object. |
| thermal energy | the amount of energy an object has |
| chemical energy | work that's formed by the arrangement of atoms in a molecule. |
| ATP | the main energy source that a cell uses. |
| chloroplast | organelles that are fond in plant cells. |
| thylakoid | circular sacs that are inside the stroma of a chloroplast. |
| light reactions | convert the sun's energy to chemical energy using chemical reactions. |
| chlorophyll | gives plants there green color. Also splits water molecular in photosynthesis using light energy. |
| Calvin Cycle | a cycle that's in plants that creates sugar from carbon dioxide. |
| stroma | think liquids in the membrane of the chloroplast. |
| equation for photosynthesis | Crabon dioxide plus water goes to (light) sugar plus oxygen. |
| wavelength | the distance between adjacent waves. |
| electromagnetic spectrum | types of electromagnetic energy that turn from gamma waves to radio wave |
| pigment | A chemical that decides a substances color. |
| paper chromatography | Laboratory technique used to observe the different pigments in a material |
| photosytem | A group of chlorophyll and other molecules in a thylakoid. |
| mitochondria | * |
| glycolysis | The splitting of glucose molecule. |
| aerobic | Needing oxygen |
| electron transport chain | A series of electron carrier molecules that turn to electrons and release energy during cellular respiration. |
| metabolism | All of a cells chemical process |
| Kerbs cycle | Stage of cellular respiration that finishes the breakdown of pyruvic acid molecules. |
| equation for cellular respiration | * |
| ATP sythase | Protein structure in cell mitochondria that uses energy from H+ ions to convert ADP to ATP. |
