Functioning ecosystems
This term refers to the variety of life forms in a particular habitat or ecosystem.
What is biodiversity?
The species that has the greatest population density in a given area.
What is a dominant species?
This type of succession occurs in areas where soil remains after a disturbance, such as after a forest fire.
What is secondary succession?
It is the role and space that an organism fills in an ecosystem, including all its interactions with the biotic and abiotic factors of its environment.
What is an ecological niche?
To evaluate the worth, significance or status of something.
What is appraise?
It is the primary source of energy in most ecosystems.
What is the sun?
Bacteria, rabbits and other r-strategist species have this type of growth.
What is exponential growth?
Ice core samples, deep sea sediments and the thickness of tree growth rings can all be used to determine past levels of this greenhouse gas.
What is carbon dioxide?
It is a plant or animal that plays a unique and crucial role in the way an ecosystem functions.
What is a keystone species?
In science, the likelihood that another experimenter will obtain the same results (or very similar results) if they perform exactly the same experiment under the same conditions.
What is reliability?
It is the process that converts atmospheric nitrogen into a form that plants can use.
What is nitrogen fixation?
When you can't count all of them, this index is used to estimate population size.
What is the Lincoln index?
It starts with rocks and colonisers, but ends with a climax community.
What is primary succession?
It is the size of the population that can be supported indefinitely on the available resources and services of that ecosystem.
What is carrying capacity (K)?
In science, the extent to which tests measure what was intended; the extent to which data, inferences and actions produced from tests and other processes are accurate.
What is validity?
This chemical equation is responsible for converting carbon dioxide into biomass.
What is respiration?
These factors will all limit population growth and reduce carrying capacity - competition for resources, predation and disease.
What are biotic limiting factors?
It describes an intermediate community found in ecological succession in an ecosystem advancing towards its climax community.
What is a sere?
It is the rate at which solar energy is converted into chemical energy by autotrophs.
What is gross primary production (GPP)?
It can be indicated by confidence intervals, inferential statistics, statistical measures of spread, like range and standard deviation.
What is uncertainty?
Ammonia, nitrate, nitrite, and nitrogen gas are all part of this process?
What is the nitrogen cycle?
One refers to the number of the species that may be found in a region. The other refers to the numbers of each species in a region at a time.
What are species richness and species abundance?
This occurs when you build a highway through a forest that prevents the movement of fauna, isolates populations and causes reduced biodiversity.
What is Habitat fragmentation?
It is the build-up of nutrients in water that can result in oxygen depletion.
What is eutrophication?
They are weak points or disadvantages that make evidence less effective.
What are limitations?
