Question 1: What is the largest reservoir of nitrogen on Earth?

Answer:

-The largest reservoir of nitrogen is found in the atmosphere, mostly as nitrogen gas (N2) Question 2: What is the difference between a carbon source and a carbon sink? What are some examples of carbon sources?

Answer:

-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 Question 3: Would warmer average global temperatures increase or decrease net primary productivity in most terrestrial biomes?

Answer:

• 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

Question 4: What is the energy available to consumers after subtracting the energy used by plants from the total energy transformed by the process of photosynthesis?

Answer:

-Net primary productivity

Question 5: What biotic factors cycle phosphorus through an ecosystem? How?

Answer:

-Phosphorous, also in the form of phosphate, may be be decomposed by decomposers, which are also living Question 6: What is the name of the process that allows species to coexist in an ecosystem by dividing up resources and avoiding competition?

Answer:

-Resource partitioning or niche differentiation Question 7: Between vegetation, the ocean, and sedimentary rock, which carbon sink holds carbon compounds for the shortest period of time?

Answer:

-Carbon Dioxide Question 8: What is the name of a symbiotic relationship in which both organisms benefit?

Answer:

-Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

Question 9: Which biogeochemical cycle lacks an atmospheric component?

Answer:

-The phosphorus cycle

Question 10: What is the largest reservoir of fresh water on Earth?

Answer:

• glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on

Earth

Question 11: Other than the water cycle, what other biogeochemical cycle relies on the conversion of key compounds through photosynthesis?

Answer:

-carbon cycle Question 12: In a food web with four trophic levels of consumers, which trophic level has the least amount of energy available for its consumers?

Answer:

-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.Question 13: What is the name of the process of converting nitrogen gas from the atmosphere into usable forms available to producers?

Answer:

-nitrogen fixation

Question 14: Which terrestrial biome has the highest net primary productivity?

Answer:

-tropical forests Question 15: What freshwater biome is characterized by fast-flowing water that can transport sediment and organic material?

Answer:

-River biome

Question 16: Describe the typical flow of energy through an ecosystem.

Answer:

-Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks Question 17: List factors that would contribute to higher levels of net primary productivity.

Answer:

• temperature, moisture, and nutrient availability

Question 18: What is created when niches overlap in an ecosystem?

Answer:

-interspecific competition Question 19: What is Earth's most biologically diverse marine biome found in shallow waters off the coastline?

Answer:

-Coral Reefs Question 20: What is a microscopic primary producer commonly found in aquatic food chains?

Answer:

-Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic Question 21: What abiotic factor is a key component of the hydrologic cycle by powering the movement of water by evaporation?

Answer:

-water vapor

Question 22: What are some benefits of no-till agriculture?

Answer:

-The no-till farmer will see an increase in the organic matter of the soil, and a decrease in the amount of erosion.Question 23: What kind of aquatic biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from large trees?

Answer:

-freshwater wetlands Question 24: 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?

Answer:

-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
