Q

The capacity of an area to generate a constant supply of renewable resources. The number of resources a region can use in order to maintain stability.

A

Biocapacity.

43
Q

Those who believe: Earth has unlimited supply of resources. If resources run out, they can be found elsewhere. Humans are the masters of Earth.

A

Frontier Ethic

44

45
Q

Those who believe: The entire planet deserves respect, not just the living, regardless of the utility. Humans are a member of the ecological community and are not the conqueror.

A

Food Chain

59
Q

Energy lost in form of heat.

A

Chemical Reaction

60
Q

A biochemical process where nitrogen is converted into many different forms and passes through the atmosphere to the soil, to organisms and back into the atmosphere.

A

Definition of Nitrogen Cycle

61
Q

Nitrogen fixation, nitrification, denitrification, decay, putrefaction

A

Processes in Nitrogen Cycle

62
Q

The atmosphere brings nitrogen to the soil, and then plants get the nitrogen from the soil due to plants absorbing through their roots and assimilation. Then animals eat these plants and gain that nitrogen also due to assimilation, and once they die, decomposers break down these animals, and the nutrients, and the nitrogen comes back to the soil.

A

The Nitrogen Cycle

63
Q

Solar radiation from the Sun, earth’s rotation, global patterns of air and water circulation, gasses in the atmosphere, earth’s surface features.

A

Factors that influence climate

64
Q

A warming of Earth’s surface and troposphere. Caused by the presence of water vapor, carbon dioxide, methane and certain other gasses in air.

A

Greenhouse Effect

65
Q

State of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc. Changes faster/more often.

A

Weather!

66
Q

Long term average of weather typically averaged over 30-year period. Much slower changes.

A

Climate

67
Q

The harvest of a specific natural resource. How much can be used without reducing it’s available supply.

A
