bacteria

which one represents a carbon source

burning of fossil fuels

the rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time

cellular respiration

this biome is found in shallow waters off the coastline and is earths most biologically diverse marine biome

coral reefs

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

gross primary productivity

water from the ocean evaporates and condenses in the atmosphere

hydrologic cycle

which of the following smaller reservoirs of freshwater are missing from the diagram

ice caps

which statement best explains how the energy is transferred

if a primary producer stores 100,000 cal of energy then the tertiary consumer will have 10 energy available

which trophic level has the least available energy in the kilojoules in this food web

killer whale

In reef ecosystems, corals often have microalgae living inside them. The algae supply the corals with nutrients, and the coral give shelter to the algae. Which of the following interactions best describes the relationship between the corals and the algae

mutalism

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 illustrated by the downward arrows from the atmosphere that show the conversion of nitrogen gas into usable forms available to producers

nitrogen assimilation

this freshwater biome is characterized by fast flowing water that can originate from underground springs or runoff which carries sediment and organic material

open ocean

which of the following trophic levels represents a primary producer in an aquatic food chain

phytoplankton

which of the following best describes the flow of energy in most terrestrial and near marine ecosystems

producers use energy from the sun to make organ matter

the majority of the nitrogen on earth can be found in which of the following reservoirs

the atmosphere

which of the following biogeochemical cycles includes the processes of buffering ocean pH and photosynthesis

the carbon cycle

which of the following best describes what is represent by the arrows in the food web

the flow of energy

which of the following describes the most likely to change to terrestrial biomes resulting from warmer average global temperatures

the global distribution of mid latitude biomes such as grasslands and temperate rain forest would increase

which of the following statements is best supported by the diagram of the phosphorus cycle

the phosphates absorbed by animal tissue through consumption eventually return to the soil

which of the following best identifies a key component of the hydrologic cycle that powers the movement of water and is missing from the diagram

the sun

The continuous process by which water moves from Earth's surface to the atmosphere and back

the water cycle

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 less algal growth in the nearby ocean

tropical rain forest

which of the following terrestrial biome has the highest primary productivity per unit area

tropical rain forest

which of the following best describes an example of resource partitioning in an ecosystem

two different bird species feed from the same oak tree; one eats acorn and the other eats insects in the bark

which represents a carbon sink that holds carbon compounds for the shortest period of time

vegetation

which of the following best describes a terrestrial ecosystem that will have the high NPP

warm temperatures high rainfall consistent sunlight
