| Question | Answer |
|---|---|
| What is the name of the process of converting nitrogen gas from the atmosphere into usable forms available to producers? | -nitrogen fixation |
| What type of organisms are required to complete the nitrogen cycle, including the process of denitrification? | -nitrogen fixers, nitrifying bacteria, and denitrifying bacteria. |
| What is the largest reservoir of nitrogen on Earth? | -The largest reservoir of nitrogen is found in the atmosphere, mostly as nitrogen gas (N2) |
| What abiotic factor is a key component of the hydrologic cycle by powering the movement of water by evaporation? | -water vapor |
| What is the largest reservoir of fresh water on Earth? | - glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth |
| In a food web with four trophic levels of consumers, which trophic level has the least amount of energy available for its consumers? | -It follows that the carnivores (secondary consumers) that feed on herbivores and detritivores and those that eat other carnivores (tertiary consumers) have the lowest amount of energy available to them. |
| What is created when niches overlap in an ecosystem? | -interspecific competition |
| What is the name of a symbiotic relationship in which both organisms benefit? | -Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions. |
| What is the name of the process that allows species to coexist in an ecosystem by dividing up resources and avoiding competition? | -Resource partitioning or niche differentiation |
| Would warmer average global temperatures increase or decrease net primary productivity in most terrestrial biomes? | - The most likely change to terrestrial biomes resulting from warmer average global temperatures would be that high-latitude biomes, such as the tundra, would experience a decrease in net primary productivity |
| Which terrestrial biome has the highest net primary productivity? | -tropical forests |
| What kind of aquatic biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from large trees? | -freshwater wetlands |
| What is Earth’s most biologically diverse marine biome found in shallow waters off the coastline? | -Coral Reefs |
| What freshwater biome is characterized by fast-flowing water that can transport sediment and organic material? | -River biome |
| Other than the water cycle, what other biogeochemical cycle relies on the conversion of key compounds through photosynthesis? | -carbon cycle |
| What is the difference between a carbon source and a carbon sink? What are some examples of carbon sources? | -A carbon sink is anything that absorbs more carbon from the atmosphere than it releases – for example, plants, the ocean and soil. In contrast, a carbon source is anything that releases more carbon into the atmosphere than it absorbs |
| Between vegetation, the ocean, and sedimentary rock, which carbon sink holds carbon compounds for the shortest period of time? | -Carbon Dioxide |
| Which biogeochemical cycle lacks an atmospheric component? | -The phosphorus cycle |
| What biotic factors cycle phosphorus through an ecosystem? How? | -Phosphorous, also in the form of phosphate, may be be decomposed by decomposers, which are also living |
| What are some benefits of no-till agriculture? | -The no-till farmer will see an increase in the organic matter of the soil, and a decrease in the amount of erosion. |
| How does water return to the atmosphere in the water cycle? How does it convert back into liquid once in the atmosphere? | - Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation). |
| What is the term for the total rate of photosynthesis in a given area? | -Gross primary productivity is the total rate of photosynthesis in a given area. |
| Which rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time, primary productivity or cellular respiration? | -The rate of reaction that can be measured in the dark by determining the amount of oxygen gas consumed in a period of time is the rate of respiration |
| What is the energy available to consumers after subtracting the energy used by plants from the total energy transformed by the process of photosynthesis? | -Net primary productivity |
| Describe the typical flow of energy through an ecosystem. | -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks |
| List factors that would contribute to higher levels of net primary productivity. | - temperature, moisture, and nutrient availability |
| What is a microscopic primary producer commonly found in aquatic food chains? | -Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic |
