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
