| Term | Definition |
|---|---|
| Carrying Capacity | The number of people or other living organisms, or crops that a region can support without environmental degradation |
| Cellular Respiration | Metabolic reactions that use the energy primarily from carbohydrate but also fatty acid or amino acid breakdown ATP molecules |
| Chemical Equations | A symbiotic representation of what happens when chemicals come in contact with one another |
| Climax Community | Community that results when succession has come to an end |
| Commensalism | Relationship where one species benefits and the other is neither harmed nor benefited |
| Consumer | Organism that feeds on other organisms in a food chain; p consumers eat plants, And S consumers eat animals |
| Cyclic Growth | The food cycle growth |
| Decomposer | A bacteria or fungus that breaks down other organic matter into nutrients that are then recycled into the environment |
| Density-Dependant Factors | Biotic factor sush as disease and competition, that affects population size according to the populations density |
| Density-Independant Factors | Abiotic factors such as fire and flood that affect population size independent of the population density |
| Ecological Succssion | The gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing |
| Energy Flow | Gradual replacement of communities in an area following a disburance (sec). Or creation of new soil (pri) |
| Logistic Growth | Occurs when the growth rate decreases as the population reaches carrying capacity |
| Mutualism | A relationship where both organisms benefit |
| Parasitism | A relationship in which one species (parasite) in terms of growth and reproduction to harm the other species |
| Photosynthesis | Process where plants make their own energy from the sun |
| Pioneer Species | Are a hardy species which are the first to colonize previously disrupted or damaged ecosystems. |
| Population | Group of organisms of the same species occupying a certain area in the ecosystem |
| Producer | Photosynthetic organism at the start of a grazing food chain that makes its own food. eg. Plants , trees, flowers, bugs, etc |
| Products | Substance that forms as the result of a reaction |
| Pyramid of Energy | Shows the energy flow in an ecosystem |
| Reactants | Substance that participates in a reaction |
| Steady State | Is a more general situation than dyanamic equilibrium |
| Symbiosis | Relationship that occurs when 2 different species live together in a unique way it may be beneficial, neutral, or detrimental to one and or the other species |
| Exponential Growth | Growth particularly of a population in which the increase occurs in the same manner as compound interest |
