| Question | Answer |
|---|---|
| Define Population Density | The number of individuals in a given area |
| Define Dispersion | The way individuals are arranged in space |
| Define Random Dispersion | A individuals scattered randomly across a given space, usually living independently |
| Define Uniform Dispersion | Individuals are separated at equal distance, which usually forms a pattern, usually due to resource competition |
| Define Clumped Dispersion | Individuals that are grouped in some places but absent in others, usually due to resources being patchy |
| Factors of Population Size | Number of Births, Deaths, and Immigration & Emmigration |
| What is the Growth Rate(r) Calculation? | Birth Rate - Death Rate |
| Define Exponential Growth | The growth rate stays the same and the population grows steadily, mainly due to having a good amount of resources |
| Define Logistic Growth | The growth model for a population which considers the carrying capacity |
| Define Carrying Capacity | The population size an enviorment can sustain |
| Define Density Dependant Factor | Limited resources that deplete at a rate based on their population's density, limiting the population size |
| Define Density Independant Factor | Factors that do not depend on the population, but affect it nonetheless |
| Define R-Strategist | Species that grow grandly when the environment is right, which leads to briefly large populations, but quickly decreases when the conditions aren't suitable any more |
| Define K-Strategist | Species that grow slowly, with the population size staying around the carrying capacity, along with them having a long life, slow maturity, and reproduction later in life |
| Define Carbon | An element that occurs in all organic compounds and every part of life, and participates in the carbon cycle |
| How much Carbon on Earth participates in the carbon cycle? | Less than 1% |
| What three ways can Carbon return to the Air or Water in? | Respiration, Erosion, and Combustion |
| Define Respiration | Where organisms undergo cellular respiration (breathing), using oxygen to break down food, with CO2 being a byproduct of the reaction (exhaling) |
| Define Erosion | Where marine life use carbon to make shells (made of calcium carbonate), which when they die, breaks down into CO2 and causes it to return to atmospshere |
| Define Combustion | When carbon is made into fossil fuels and then burned, causing it to float back into the atmosphere |
| Define Greenhouse Gas | Gases in the atmosphere that raise the surface temperature of Earth |
| Define Photosynthesis | Where plants use water, sunlight, and Carbon Dioxide to create oxygen and energy in the form of sugar |
