Ecology Test Review
Study these words till you get them right.
| Question | Answer |
|---|---|
| Biodiversity | The number of different kind of organisms in an area |
| Greatest threat to biodiversity? | Habitat Loss |
| Biotic factors different from Abiotic factors? | Biotic are living and Abiotic are non-living |
| Examples of abiotic factors? | Sun, Water, and Air |
| Examples of biotic factors? | Animals, Plants, and Bacteria |
| What do decomposers do? | Recycle Nutrients |
| Examples of decomposers? | Bacteria and Fungi |
| 4 processes that are part of the water cycle? | Evaporation, precipitation, condensation, runoff, accumulation, transpiration, seepage |
| Evaporatoin | water to water vapor |
| Precipitation | Rain, Sleet, or Snow |
| Condesesation | Water Vapor to Liqud |
| Runoff | More water than land can absorb |
| Accumulation | Water that is stored on Earth's surface. |
| Transpiration | Plants give water to water vapor |
| What is one way that water moves from a biotic to an abiotic factor? | Transpiration (from plants to the air) |
| Oxygen and carbon dioxide are cycled in the carbon cycle by which two processes? | Photosynthesis and cell respiration |
| How is nitrogen cycled from biotic to abiotic factors? | Decomposition (organisms to the soil) |
| Is more energy available at the top of the food pyramid or the bottom? | At the bottom; energy is lost between each trophic level |
| How much energy is lost between each trophic level in a food chain? | 90% |
| An example of a food chain with three trophic levels and use ecology vocabulary terms to label the different trophic levels | Producer -> Primary Consumer -> Secondary Consumer |
| What would happen to the size of the primary consumer population if the number of secondary consumers increased? | It would decrease as more are being eaten |
| Which of the following receives the least amount of energy? | Tertiary Consumers |
| What is the definition of a producer? | Makes its own food (glucose) from sunlight energy (photosynthesis) |
| Examples of producers? | Plants, seaweeds and some bacteria |
| Heterotroph | An organism that eats other plants or animals for energy and nutrients |
| Autotroph | Use inorganic material to produce food through either a process as photosynthesis or chemosynthesis. |
| Carnivore | Only Eats Meat |
| Herbivore | Only Eats Green |
| Omnivore | Eats Meat and Greens |
| What is the advantage of organisms in an ecosystem not having overlapping niches? | Less competition |
| What is the population size that can be maintained in an area over time? | Carrying capacity |
| Limiting factors | Anything that makes a population's size and slows or stops it from growing |
| Mutualism | When both organisms are helped and work together |
| Commensalism | When only one organisms benefits without the other is harmed |
| Parasitism | When only one organisms benefits when the other is harmed |
