The number of sika deer more than doubled after 8 years while the population of the white tailed deer decreased by 50 percent
The sika deer out competed the white tailed deer in comsuming flowering plants and shrubs
which of the following types of organism is required to complete the nitrogen cycle including the process of denitrification
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
the total rate of photosynthesis in a given area
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
which of the following has the highest net primary productivity
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
