APES Unit 1 Practice Questions
What biome has the highest terrestrial biomes has the highest net primary productivity
Tropical rainforest
What represents a carbon sink that holds carbon compounds for the shortest period of time
Vegetation
best describes a terrestrial ecosystem that will have the highest net primary productivity
Warm temperatures, high rainfall, and consistent sunlight
How to determine the approximate number of kilocalories/meter^2/year available to herbivores in that biome?
10% of Net primary productivity
Which of the following types of organisms are required to complete the nitrogen cycle, including the process of denitrification?
Bacteria
Describe the most likely change to terrestrial biomes as a result of warmer global temperatures
Global distribution of midlatitude biomes like grasslands and temperate rainforests would increase
What is a smaller more forgotten water reservoir
Ice caps
The energy available to consumers determined by subtracting the energy used by plants from the total energy transformed by the process of photosynthesis.
Net primary productivity
Which of the following processes is from the atmosphere that show the conversion of nitrogen gas into usable forms available to producers?
Nitrogen fixation
describe the flow of energy in most terrestrial and near-surface marine ecosystems
Producers use energy from the sun to make organic matter, such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain.
Farmers in a suburban coastal town started using no-till agriculture, a practice that reduces soil erosion from their farmland. Use the image above to determine which of the following long-term effects no-till agriculture will have on the ecosystem surrounding the farmland.
There will be less algal growth in the nearby ocean.
The majority of the nitrogen on Earth can be found in which of the following reservoirs?
atmosphere
The total rate of photosynthesis in a given area.
gross primary productivity
Which of the following trophic levels represents a primary producer in an aquatic food chain?
phytoplankton
This biome is found in shallow waters off the coastline and is Earth's most biologically diverse marine biome.
Coral Reef
This biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from the large trees, and it provides the ecosystem service of filtering pollutants from water.
Freshwater Wetlands
Example of carbon source
Ocean
This freshwater biome is characterized by fast-flowing water that can originate from underground springs or runoff, which carries sediment and organic material.
Rivers
What terrestrial biome has the highest primary productivity per unit area
Tropical rainforest
Which of the following biogeochemical cycles includes the processes of buffering ocean pH and photosynthesis
carbon cycle
