Ecosystems
This is known as a species preferred habitat.
What is a niche?
A graph with a double y axis plotting monthly average temperature and precipitation is called this.
What is a climatograph?
These two features hold 68.7% of all fresh water on Earth.
What are glaciers and ice caps?
A carbon reservoir that stores more carbon than it releases is known as this. Also: name the largest one in the world.
What is a carbon sink? The Oceans.
This is the main nitrogen reservoir on Earth.
What is the atmosphere?
This type of symbiosis benefits only one species, while harming the other.
What is parasitism?
This biome has the highest level of biodiversity and rainfall.
What is the tropical rainforest?
This law regulates standards for community water supplies in the United States.
What is the Safe Drinking Water Act?
Carbon enters the biotic world through these two processes.
What are photosynthesis and chemosynthesis?
Nitrogen fixation can be biotic or abiotic, serving to transform nitrogen into these two compounds.
What are ammonia and nitrates?
This type of symbiosis benefits only one species, without harming the other.
What is commensalism?
When precipitation totals are less than the temperatures on a climatograph, it indicates this is true about a biome.
What is extreme dryness? Ex: Desert, Taiga, Tundra.
While freshwater has less than 0.5 ppt of salt, the open ocean averages this level of salinity.
What is 35 ppt?
This curve tracks atmospheric CO2 concentrations in Mauna Loa.
What is the Keeling Curve?
This step in the Nitrogen cycle features plants taking in Nitrates.
What is assimilation?
This type of competition results in increased overall species fitness.
What is INTRAspecific?
This biome is influenced by marine weather and dependent on fire.
What is Chaparral / Scrubland?
This term for the rate of photosynthesis determines the amount of energy available in an ecosystem to support life.
What is productivity?
In addition to the burning of fossil fuels, these two processes also return carbon to the atmosphere.
What are cellular respiration and decay?
This step in the Nitrogen cycle returns it as a gas to the atmosphere.
What is denitirification?
This type of competition results in resource partitioning.
What is INTERspecific?
This biome is characterized by long dry seasons and is dominated by grasses, shrubs, and grazing animals.
What is Savanna?
This species supply a large portion of the Oxygen of the planet and are found largely in the upper few hundred feet of bodies of water.
What are phytoplankton?
This substance in the Earth sequesters carbon, and it cannot be burned as a fossil fuel.
What is limestone?
These two steps in the Nitrogen cycle involve decomposers.
What are ammonification and nitrification?
