Energy Flow 22-23
Energy Flow
Term | Definition |
---|---|
Food Chains | A single pathway in which energy and nutrients are passed from one living organism to another. Energy is used up as it moves and the arrow represents energy being transferred. |
Food Webs | A network of food chains by which energy and nutrients are passed on from one living organism to another with multiple pathways. The arrows represent energy being transferred and energy is greatest at the bottom of the food web. |
Carnivore | Organisms that eat only meat. |
Omnivore | Organisms that eat both plants and meat. |
Producer | Organisms that make their own food. |
Primary Consumer | Organisms that eat producers. |
Organism | A living thing that moves, eats, respires, grows, reproduces, and shows sensitivity to stimuli. |
Herbivore | Organisms that eat only plants. |
Flow of Energy | How energy moves through an ecosystem from the sun, to producers, to consumers, and on to the next consumer, and so on. |
Terrestrial Ecosystem | A group of abiotic and boitic factors that come together to form an ecosystem that is on land. |
Decomposers | Organisms that recycle dead organisms into chemical nutrients used in soil, air, and water. |
Scavengers | Organisms that eat bodies of dead organisms. |
Secondary Consumer | Organism that eats primary consumers. |
Tertiary Consumer | Organisms that eats secondary consumers. |
Marine Ecosystem | A group of abiotic and boitic factors that come together to form an ecosystem that is in salt water. |
Freshwater Ecosystem | A group of abiotic and boitic factors that come together to form an ecosystem that is in fresh water. |
Hydrothermal Vents | A extreme environments where water is heated by underwater volcanic activity and chemosynthesis is the process producers use to create their own food due to a lack of sunlight. |
Photosynthesis | The process where green plants absorb energy from the sun and combine it with water and carbon dioxide to create glucose and oxygen. |
Chemosynthesis | A process that some organisms in extreme environments use to create their own food when there is a lack of sunlight. The reactants are carbon dioxide, water, and hydrogen sulfide and the products are sugar and sulfur compounds. |
Consumers | Organisms that get energy from eating other organisms. |
Quaternary Consumers | Carnivorous organisms that may eat primary, secondary, and tertiary consumers. Also known as an Apex Predator who is not naturally hunted by anything else in that ecosystem and is at the top trophic level of the energy pyramid. |
Heterotrophs | Organism that cannot make their own food, so they have to eat other things like plants or animals. |
Autotroph | Organism that makes its own food. |
Joule | Unit for Energy. |
Conservation of Energy | Energy can neither be created nor destroyed, Energy does not disappear, & Energy just transforms from one form into another. |
Energy Transformation | Conversion; The process of changing energy from one form to another. |
Potential Energy | Energy that is stored. |
Kinetic Energy | Energy that is in motion. |
Thermal Energy KE | Heat Energy; The total energy of atoms and molecules that are constantly in motion |
Radiant Energy KE | Solar or Light Energy; Energy caused by the movement of electromagnetic waves. |
Chemical Energy PE | Energy stored in chemical substances. |
