This biome contains plants that are adapted to prevent water loss due to the low average rainfall and high temperatures year-round.
Desert
Which of the following statements is true of aquatic biomes?
Freshwater biomes are a vital source of drinking water
Where is the majority of freshwater found on Earth?
Ice caps and Glaciers
Which of the following best describes the net primary productivity of an ecosystem?
Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem
This biome is characterized by long dry seasons and is dominated by grasses, shrubs, and grazing animals.
Savanna
primary productivity
The net amount of energy that is stored by the main energy producers
Which of the following is the best explanation for why there is such a small amount of phosphorus that moves in aquatic systems?
There is not a gaseous phase of the phosphorus cycle, and therefore the movement of phosphorus into Oceanic reservoirs is very slow
Which of the following best explains why decomposers in soils and water are important to ecosystems?
They recycle nutrients
Carbon Sink
a forest, ocean, or other natural environment viewed in terms of its ability to absorb carbon dioxide from the atmosphere
Invasive Plant
alien species that show a tendency to spread out of control
Gross Primary Productivity
amount of carbon fixed during photosynthesis by all producers in the ecosystem
Secondary Consumers
an animal that eats primary consumers, blue crab, Lobster, sea star, humpback whale
Primary Consumers
an animal that eats primary producers, mussels, oysters, Krill, copepods, shrimp
Decomposers
an organism that decomposes organic material
Resource Partitioning
division of limited resources
Photosynthesis
convert the energy from the Sun into chemical energy for food
For a primary producer, the main function of photosynthesis is to manufacture?
glucose
Savanna
non-woody plants, tropical savannas

producers
Niche
relationships between a species and the elements in its ecosystem
Producers
responsible for the production of organic compounds from atmospheric or aquatic carbon dioxide
third level of pyramid
secondary consumers
Hydrologic Cycle
the movement of water through the biosphere
gross primary productivity job
the total amount of solar energy captured by producers through photosynthesis overtime
This biome is warm and wet, with little seasonal variation in temperature and frequent precipitation.
tropical rainforest- biodiversity; warm and wet
10% rule of energy transfer
when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on
Which of the following diagrams correctly illustrates the nitrogen cycle?
you want N2 above ground on both sides
