Energy budget of forest |
This means the balances of energy occurring at three levels 1) the most solar surface of the Earth to most solar heating takes place. 2) the edge of the Earth's atmosphere where sunlight enters the system and 3 ) atmosphere in between each level the amount of incoming and outgoing energy must be equal. |
|
|
|
Evapotranspiration |
The total amount of water transpired by plants and evaporated from a landscape. Evapotranspiration increases with the temperature and amount of solar energy available to drive evaporation and transpiration. |
the climate variables of moisture and temperature are very useful for predicting and terrestrial ecosystems. Along the mean annual precipitation a second useful predictor evapotranspiration. |
|
|
Light reflected |
Because solar radiation drives photosynthesis you would expect like to be the key variable and control in primary production the depth of light penetration affect primary production throughout the photic zone ( the depth of the water in a lake or ocean that is exposed to such intensity of sunlight ) of an ocean or lake. If light were the main variable limiting primary production in the ocean we will expect production to increase along a gradient from Poles toward the equator which receives the greatest intensity of light. |

Energy flows into the world's |
This is referring to the light |
|
|
|
Net primary productivity |
It represents the storage of chemical energy that will be available to consumers in the ecosystem so that's why it's important to find out what it is. Net primary production is the amount of new biomass added in a given period of time.Meaning is equal to the gross primary production minus the energy used by the primary producers for their autotrophic respiration. (GPP - autotrophic respiration) |
|
|
|
Gross primary productivity |
Meaning the total primary production in an ecosystem is known as that ecosystems growth primary production which is also the amount of energy from light to the chemical energy of organic molecules |
Not all of this production is stored as organic material in the primary producers because they use some of the molecules as fuel in their own cellular respiration |
|
|
Biomass |
plant materials and animal waste used especially as a source of fuel. Also the amount of living matter (as in a unit area or volume of habitat
|
|
|
|
Trophic levels of consumers |
Means the various stages within ecological food chains or webs primary producers primary consumers or herbivores and secondary and higher level consumers or predators |
Food webs are based on the productivity of photosynthetic organisms such as algae and plants the autotrophic organisms are capable of fixing some of the reviews energy of solar radiation into simple organic compounds |
|
|
Recyclers |
Referring to |
|
|
|
Detritivores |
means decomposers which refers to Consumers that get their energy from detritus. This is also a nonliving organic material such as the remains of dead organisms feces and fallen leaves and wood. It is eaten by secondary and tertiary consumers An important group of detritivores are prokaryotes and fungi |
Baylink consumers and primary producers in an ecosystem an example is a forest birds eat earthworms that have been fed on Leaf litter and is associated with prokaryotes and fungi |
|
|
Top carnivores are rare because |
The progressive loss of energy along a food chain severely limits the abundance of top-level carnivores that an ecosystem can support. Only about 0.1% of the chemical energy fixed by photosynthesis can flow all the way through a food web to a teritary consumer like a snake or a shark |
|
|
|
Decomposers |
they are are bacteria fungi some insects, snails that eat dead things from the ground in order to get nutrients., |
|
|
|
Heat radiation |
This is solar radiation that drives photosynthesis. |
|
|
|
Highest load of toxic chemicals in the bodies of |
... |
|
|
|
Autotrophs |
they are |
|
|
|
Energy flows out of the Worlds |
As heat some of the remaining energy is used for secondary production or is used for secondary production are gross. The remaining energy is stored in organic compounds for cellular respiration and passes through it remains in the ecosystem temporarily but most of it is lost as heat after it's consumed |
|
|
|
10% rule is |
the energy transfer between trophic levels is typically only 10% efficient |
|
|
|
Primary consumers |
Herbivores which eat plants and other primary producers |
|
|
|
Secondary consumers |
Carnivores that eat herbivores |
|
|
|
Tertiary consumers |
Carnivores that eat other carnivores |
|
|
|
Net ecosystem production (NEP) |
Is a measure of the total biomass accumulation during that time that equal system production is defined as the gross primary production minus the total respiration of all organisms in the system not just primary producers as the calculation of NPP but decomposers and other heterotroph as well |
|
|
|
Production efficency |
Measurement of the efficency of animals as energy transforming using the equation Production efficency = net secondary production ×100% / assimilation of primary production |
|
|
|
Nitrogen enter the ecosystem |
Through nitrogen fixation which is the conversion of N2 to forms that can be used to synthesize organic nitrogen compounds |
