| 292935616 | Ernst Haekel | A 19th century scientists who developed the concept of ecology | |
| 292935617 | Ecology | The study of systems that include interactions among organisms and between organisms and the environment | |
| 292935618 | Biotic V. Abiotic | The _______ parts of an environment include the living parts whereas the ________ parts of the environment include the non-living parts of the environment | |
| 292935619 | Species | A group of similar organmisms whose memebers freely interbreed with one another in the wild to produce fertile offspring | |
| 292935620 | Population | A group of organisms of the same species that live in the same area at the same time | |
| 292935621 | Community | A natural association that consists of all the populatgions of different species that live and interact within an area at the same time | |
| 292935622 | Ecosystem | A community and its physical environment | |
| 292935623 | Landscape | A region that includes several interacting ecosystems | |
| 292935624 | Biosphere | The parts of Earth's atmosphere, ocean and land surface and soil that contain all living organisms | |
| 292935625 | Atmosphere | The gaseous envelope surrounding Earth | |
| 292935626 | Hydrosphere | The Earth's supply of water; liquid or frozen | |
| 292935627 | Lithosphere | The soil and rock of Earth's surface | |
| 292935628 | Energy | The capacity or ability to do work | |
| 292935629 | Chemical Energy | This is a type of energy stored in the bonds of molecules | |
| 292935630 | Radiant Energy | This type of energy includes radio waves, visible light, and X-Rays that is transmitted as electromagnetic waves | |
| 292935631 | Solar Energy | The radiant energy that comes from the sun; it includes UV radiation, visible light, and infared radiation | |
| 292935632 | Thermodynamcis | The study of energy ands its transformations | |
| 292935633 | 1st Law of Thermodynamics | This law states that: "energy cannot be created or destroyed, though it can change from one form to another." | |
| 292935634 | 2nd Law of Thermodynamics | This law states that: "when energy is converted from one form to another, some of it is degraded into heat, a less useable form that disperses into the environment." | |
| 292935635 | Entropy | A measure of the disorder of less useable energy...Ex. A high entropy is disorganized heat and low entropy is organized heat | |
| 292935636 | The Chemical Sequence of Photosynthesis | 6CO2 + 12H2O + radiant energy ---> C6H12O6 + 6H2O + 6O2 | |
| 292935637 | Chemical Sequence of Cellular Respiration | C6H12O6 + 6O2 + 6H2O --> 6CO2 + 12H2O + energy | |
| 292935638 | Energy Flow | The passage of energy in a one way direction through an ecosystem | |
| 292935639 | Trophic Level | An organism's position in a food chain, which is determined by its feeding relationships | |
| 292935640 | Food Web | A representation of the interlockign food chains that connect all organisms in an ecosystem | |
| 292935641 | Pyramid of Numbers | Show the number of organisms at each trophic level in a given ecosystem, with greaer numbers illustrated by a larger area for the section of that pyramid | |
| 292935642 | Pyramid of Biomass | Illustrates the total biomass at each successive trophic level | |
| 292935643 | Pyramid of Energy | Illustrates the energy content of bionass at each trophic level. (Expressed as Kilocalories per square meter per year) | |
| 292935644 | Gross Primary Porductivity (GPP) | The total amount of photosynthetic energy that plants capture and assimilate in a given period | |
| 292935645 | Net Primary Productivity (NPP) | Productivity after respiration losses are subtracted | |
| 292935646 | Peter Vitousek | In 1986, this man calculated how much of the global NPP is appropriated for the human economy and are therefore not transferred to other organisms | |
| 292935647 | Stuart Rojstaczer | In 2001, this man calculated and found that 32% of the global NPP is appropriated for the human economy | |
| 292935648 | K. Heinz Erb | In 2007, he found that humans account for 25% of the global land based NPP for food, forage (for livestock), and wood |
