| Term | Picture |
|---|---|
| Anaerobe | An organism that can grow without oxygen present |
| Anaerobic respiration | Process that produces cellular energy without oxygen |
| ATP or adenosine triphosphate | Energy-carrying biological molecule that drives cellular activities when broken down |
| autotrophs | Organisms that produce their own food such as plants, algae and chemosynthetic organisms |
| Biomass | total amount of organisms in a given area or volume |
| carnivores | Consumers that prey on other consumers such as lions |
| cell membrane | A double layer of lipids and proteins that surrounds a cell and separates the cytoplasm from its surrounding environment |
| Cellular respiration | process in which organic molecules are broken down to release energy for use by the cell |
| cellular respiration formula | C6H12O6+6 O2→6CO2+6 H2O+energyC6H12O6+6 O2→6CO2+6 H2O+energy |
| chemical energy | energy stored in the bonds of chemical compounds, such as those in glucose |
| Chemosynthesis | uses chemical energy instead of light energy by converting carbon or methane into organic matter using inorganic molecules such as hydrogen sulfide or methane as an energy source |
| chloroplast | Organelle where photosynthesis occurs |
| Decomposers | break down dead or decaying organisms. Examples of decomposers include fungi and bacteria. |
| Detritivores | feed on dead organic matter and contribute to decomposition and nutrient cycles |
| Endolith | An organism that lives inside rock or in the pores between mineral grains |
| eukaryotic | A cell with membrane-bound nucleus and organelles; is generally larger and more complex |
| Food chain | simple models that show the flow of energy from one organism to another |
| Food web | model the many interconnected food chains through an ecosystem |
| Gross primary productivity | the overall amount of energy captured by plants and other photosynthetic organisms |
| Halophile | An organism requiring high amounts of salt for growth |
| herbivore | A consumer that eats only plants |
| Heterotrophs | organisms that consume other organisms in order to gain energy and are also known as consumers |
| law of conservation of mass | matter cannot be created nor destroyed |
| Matter | anything that takes up space and has mass and follows the Law of Conservation of Mass. |
| Methanogen | An organism that produces methane from the reaction of hydrogen and carbon dioxide |
| mitochondria. | Membrane-bound organelle that converts fuel into energy that is available to the rest of the cell |
| net primary productivity | adjust amount of energy in an ecosystem due to energy use by organisms for respiration |
| omnivore | an organism that eats both plants and animals |
| photosynthesis | The process by which plants, algae, and some bacteria convert radiant energy from the sun into chemical energy |
| photosynthesis formula | carbon dioxide+water+radian tenergy→glucose+oxygen |
| primary consumers | eat the producers |
| Producer | organisms that make their own food such as plants (also known as autotrophs) |
| prokaryotic | A cell without a nucleus or other membrane-bound organelles |
| radiant energy | Light energy from the sun |
| secondary consumers | carnivores that eat the primary consumers |
| Stress responses | reactions to situations that throw us off balance |
| Stressors | things or situations that cause us tension |
| third (tertiary) consumers | carnivores that eat other carnivores |
| trophic level | Each level in a food chain or food web |
