Ecology and Biodiversity

Graphing

100

This variable is not measured - it is determined by the scientist when planning the experiment

independent variable

200

The variable is the measured variable in an experiment

dependent variable

300

SULTAN stands for 

Scale, Units, Label(s), Title, Accuracy and Neatness

400

These variables remain constant throughout the experiment, ensuring uniform results across all measured samples

control variable

500

These appear along each axis, telling us what we is being studied

Either Labels or Units, both acceptable (but they are not the same!!)

BioDiversity I

100

This describes how many individuals of a species are i a given area

Population Density

200

This describes members of a species that are evenly spread throughout an ecosystem or biome

uniform dispersion

300

This describes members of a species that are "arbitrarily" dispersed throughout an ecosystem or biome

random dispersion

400

This describes members of a species whose distribution can be described as bunched or "_______"

clumped dispersion

500

This describes "unchecked" or "runaway" population growth

exponential growth

Biodiversity II

100

This describes population growth that has leveled off

logistic growth

200

This is the level at which an ecosytem has reached the max amount, more or less, of the number of organisms it can support

carrying capacity

300

Larger than an ecosystem, smaller than a biosphere

Biome

400

More than one individual, but not a community

population

500

more than population, contains member of different species

community

Ecology I

100

This amount of energy is transferred to the next highest step in an energy pyramid

10%

200

in an energy pyramid there are always the most of these

primary producers (autotrophs is OK, plants is OK)

300

This group eats the primary producers

primary consumers

400

this group eats the primary consumers

secondary consumers

500

If primary producers create 1000kcal of energy from the Sun, and the pyramid contains primary producers>primary consumers>secondary consumers>apex predators - how much energy ends up in the apex predator level

1 kcal

Ecology II

100

the top of a food pyramid contains this type of organisms

Apex predators (or tertiary consumers)

200

in a food web removal of one tiny organism does/does not affect the whole web

does! 

300

in an energy pyramid, energy is lost as we move up the pyramid due to 

biological activities (everyday life - like chasing rabbits!)

400

In the nitrogen cycle, these "fix" nitrogen making it useful to plants and humans

bacteria

500

In the Nitrogen cycle, this type of vegetable (like beans) gather the nitrogen once it has been fixed

legumes
