Bio: Trophic Reading
Tropic Reading 7.1 & 36.1
| Word | Definition |
|---|---|
| Energy | Organism that breaks down food to maintain homeostasis |
| Autotroph | Organism that makes its own food. |
| Primary Consumers | Consumer that feeds directly on producers. |
| Omnivores | Consumer that eats both producers and consumers. |
| Detritus | Wastes and reamains of dead organsims. |
| 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 organsims. |
| 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 Level | Feeding level in an ecosystem. |
| Food Chain | Pathway of food transfer from one trophic level to another |
| Biomass | The total mass of organisms in a given area or volume. |
| Herbivores | Consumers that eats only producers. |
| Tertiary Consumers | Consumer that eats secondary comsumers. |
| Cellular Respiration | Chemical process that uses oxygen to convert chemical energy stored in organic molecules into adenosine triphosphate (ATP) |
| Primary Productivity | Rate at which producers in an ecosystem build biomass. |
| Energy Pyramid | Diagram representing energy loss from one trophic level to the next. |
| 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. |
| Kinetic Energy | Energy of motion |
| Calorie | Amount of energy required to raise the temperature of 1 g of water 1 degrees Celsius |
| Potential Energy | Energy stored due to an object's position or arrangement. |
| ATP (Adenosine Triphosphate) | Main energy source that cells use for most of their work. |
| Thermal Energy | Total amount of energy associated with the random movement of atoms and molecules in a sample of matter. |
| Chemical Energy | Potential to perform work due to the arrangement of atoms within molecules. |
