1.B.1 Energy Flow in biogeochemical Cycles

# data[].attributes.body
All ecosystems depend on a continuous inflow
of high-quality energy in order to maintain their
structure and function of transferring matter
between the environment and organisms via
biogeochemical cycles.

# data[].attributes.body
Positive and negative feedback loops can each play a role in food webs. When one species is
removed from or added to a specific food web, the rest of the food web can be affected.

# data[].attributes.body
Biogeochemical cycles are essential for life and each cycle demonstrates the conservation of matter.

# data[].attributes.body
A food web is a model of an interlocking pattern of food chains that depicts the flow of energy and nutrients in two or more food chains.

# data[].attributes.body
In terrestrial and near-surface marine communities, energy flows from the sun to producers in the lowest trophic levels and then upward to higher trophic levels.

# data[].attributes.body
The 10% rule explains how in the transfer of energy from one trophic level to the next, only about 10% of the energy is passed on.

# data[].attributes.body
The loss of energy that occurs when energy moves from lower to higher trophic levels can be explained through the laws of thermodynamics.

1.6 (1.F.1) - What is the Phosphorus Cycle?

# data[].attributes.body
The phosphorus cycle is the movement of atoms and molecules containing the element phosphorus between sources and sinks (reservoirs).

# data[].attributes.body
The worldwide distribution of biomes is dynamic; the distribution has changed in the past and may shift again as a result of global climate changes.

1.1 1.3.A     Competition within species

# data[].attributes.body
Competition can occur within or between species in an ecosystem where there are limited resources. Resource partitioning— using the resources in different ways, places, or at different times—can reduce the negative impact of competition on survival.

1.6 (1.F.2)-Major Reservoirs of  Phosphorus 

# data[].attributes.body
The major reservoirs of phosphorus in the phosphorus cycle are rock and sediments that contain phosphorus-bearing minerals

In a predator-prey relationship, the predator is an organism that eats another organism.

1.6 (1.F.3) - The Scarcity of Phosphorus

# data[].attributes.body
There is no atmospheric component in the phosphorus cycle, and the limitations this imposes on the return of phosphorus from the ocean to land make phosphorus naturally scarce in aquatic and many terrestrial ecosystems. In undisturbed ecosystems, phosphorus is the limiting factor in biological systems.

Most of the reservoirs in which nitrogen compounds occur in the nitrogen cycle hold those compounds for relatively short periods of time, or, in more concise terms, are considered short-term reservoirs.

# data[].attributes.body
The nitrogen cycle is the movement of atoms and molecules containing the element nitrogen between sources and sinks.

# data[].attributes.body
A biome contains characteristic communities of plants and animals that result from, and are adapted to, its climate

# data[].attributes.body
The carbon cycle is the movement of atoms and molecules containing the element carbon between sources and sinks.

# data[].attributes.body
The chemical processes by which atmospheric nitrogen is converted (by either natural or an industrial means) to a form of nitrogen (like ammonia) that can be taken up by plants to form plant tissue.

# data[].attributes.body
Some of the reservoirs in which carbon compounds occur in the carbon cycle hold those compounds for long periods of time, while some hold them for relatively short periods of time.

# data[].attributes.body
Major terrestrial biomes include taiga, temperate rainforests, temperate seasonal forests, tropical rainforests, shrubland, temperate grassland, savanna, desert, and tundra.

# data[].attributes.body
Marine biomes include oceans, coral reefs, marshland, and estuaries. Algae in marine biomes supply a large portion of the Earth’s oxygen, and also take in carbon dioxide from the atmosphere

# data[].attributes.body
Symbiosis is a close and long-term interaction between two species in an ecosystem. Types of symbiosis include mutualism, commensalism, and parasitism.

1.7 (1.G.1) What is the Hydrologic Cycle?

# data[].attributes.body
The hydrologic cycle, which is powered by the sun, is the movement of water in its various solid, liquid, and gaseous phases between sources and sinks.

1.2: 1.B.3 nonmineral terrestrial natural resources distribution 

# data[].attributes.body
The global distribution of nonmineral terrestrial natural resources, such as water and trees for lumber, varies because of some combination of climate, geography, latitude and altitude, nutrient availability, and soil.

# data[].attributes.body
Productivity is measured in units of energy per unit area per unit time (e.g., kcal/m2/yr).

# data[].attributes.body
Most red light is absorbed in the upper 1 meter of water, and blue light only penetrates deeper than 100 meters in the clearest water. This affects photosynthesis in aquatic ecosystems, whose photosynthesizes have adapted mechanisms to address the lack of visible light

# data[].attributes.body
Plant and animal decomposition have led to the storage of carbon over millions of years. The burning of fossil fuels quickly moves that stored carbon into atmospheric carbon, in the form of carbon dioxide.

1.5 (1.E.4) - Major Reservoir of Nitrogen

# data[].attributes.body
The largest reservoir of nitrogen on Earth is the dinitrogen gas (N2) in the atmosphere. N2 is also the major form of nitrogen in the ocean. It is important to note that this form of nitrogen cannot be taken up by plants, that is why nitrogen fixation is critical.

# data[].attributes.body
The oceans are the primary reservoir of water at the Earth’s surface, with ice caps and groundwater acting as much smaller reservoirs

Net primary productivity is the rate of energy storage by photosynthesizes in a given area, after subtracting the energy lost to respiration.

# data[].attributes.body
The global distribution of non mineral marine natural resources, such as different types of fish, varies because of some combination of salinity, depth, turbidity, nutrient availability, and temperature.

Gross primary productivity is the total rate of photosynthesis in a given area.
