100

The first level of ecological organization that would consist of one deer.

Organism

100

The step in the water cycle that shows the evaporation of water from plants.

What is transpiration 

100

Population grows without limit

Exponential Growth

100

Aspects of the environment that limit the size a population can reach.

Limiting Factors

100

These are the two types of reproduction.

Sexual and Asexual

200

The zone of life on earth, encompassing all of Earth's ecosystems.

Biosphere

200

The biggest human impact on the carbon cycle. 

Combustion

200

This is the negative impact of fertilizer.

The use of fertilizers adds WAY too much

nitrogen to the soil, creating an imbalance.

200

When referring to the non living factors in an environment we call them

Abiotic

200

This is a change in an organism's environment.

Stimulus

300

A diagram that shows relatedness of organisms.

Cladogram

300

This is the effect that deforestation has on the water cycle.

Deforestation reduces transpiration, thus it reduces the amount of water going back into the atmosphere.

300

The theoretical maximum population that a given environment could support.

Carrying Capacity

300

Factors that can be triggered by an increase in population size and have a bigger impact on more dense populations

Density Dependent

300

All of the chemical reactions of each cell in an organism that provide energy for life’s processes and create key molecules.

What is Metabolism

400

All of the deer, birds, plants, insects, squirrels, etc. in a field.

Community

400

The process of bacteria taking nitrogen out of the atmosphere and changing it into something we can use on the ground.

Nitrogen Fixation

400

This is how animal respiration effects the carbon cycle.

Animals exhale carbon dioxide when they breathe and inhale oxygen.

400

Nearly all species in an ecosystem are affected equally by _______________ limiting factors.

Density Independent

400

Individual organisms _____ evolve

Cannot

500

Community PLUS all of the abiotic factors in the environment.

Ecosystem

500

What is the missing stage?

Nitrogen fixation, consumption, ammonification, nitrification, and denitrification.

Decomposition

500

This is what's created after millions of years of heat and compression on organic matter.

Fossil Fuels ( Coal and Petroleum)

500

Disease is a ____________________ factor.

Density Dependent

500

What must something be composed of to be considered living?

One or more cells & DNA or RNA
