The third thing scientists argue over is

Back 2

the consequences of climate change

Front 3

What are some of the qualities of coal, oil, and natural gas?

Back 3

They are formed from decayed plants
They are fossil fuels
The release carbon dioxide when they are burned

Front 6

Facts about the greenhouse effect

Back 6

It is real and helps to regulate the temperature of our planet. Water is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases. Without a natural greenhouse effect, the temperature of the Earth would be about 0°F (-18° C) instead of its present 57°F (14°C).

Front 7

Organisms at higher trophic levels tend to be fewer in number than those at lower trophic levels

Front 8

The physical location of an ecosystem in which a given species lives is called a

habitat

Front 9

Ecology is the study of the interaction of living organisms

with each other and their physical environment

Cut apart and study

Front 12

When an organism dies, the nutrients in its body

Back 12

are released by the action of decomposers

Front 13

Food webs are more commonplace than food chains because

Back 13

organisms almost always eat, and are eaten by, many different organisms

Front 14

In a food web, which typ of organism receives energy from every other type?

Back 14

decomposer

Front 15

Facts about Co2 concentration

Back 15

Pre-industrial levels of carbon dioxide (prior to the start of the Industrial Revolution) were about 280 parts per million by volume (ppmv), and current levels are about 370 ppmv.

Front 16

Animals that feed on plants are at least in the

second trophic level

Front 17

The total dry weight of the organism in an ecosystem is called

Back 17

biomass

Front 18

Becasue energy diminishes at each successive trophic level, few ecosystems can contain more then

Precipitation and evaporation are important components of

the water cycle

Front 21

The paths of water, carbon,nitrogen, and phosphorus pass from the non-living environment to living organisms and back to the non-living environment in closed circles called

environcycles

The term ________________ is used to describe the physical area in which an organism lives

Back 22

habitat

Front 23

A group of organisms of different species living together in a particular place is called a

community

Front 24

What are some examples of detritivores?

Back 24

worms
vultures
fungi

Front 25

The number of species living within an ecosystem is a measure of its

biodiversity

Front 26

Carbon is returned to the atmosphere by cellular respiration, combustion, and

erosion

Front 27

Facts about the sea level

Back 27

global mean sea level has been rising at an average rate of 1 to2 mm/year over the last 100 years, which is significantly larger than the averaged over the last several thousand years.

Front 28

Facts about whether the temperature has been rising or not

Back 28

Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about 1.1°C over the past 25 years (the period with the most credible data). The warming has not been globally uniform. Some areas (including parts of the southeastern U.S.) have, in fact, cooled over the last century.

Front 29

Biotic factors in a habitat include all the physical aspects as well as the living organisms

Front 30

The first thing scientists argue over is

Back 30

Whether the climate is changing beyond natural variation in the historical temperature record

Front 31

The second thing scientists argue over

Back 31

Whether human/industrial activity is responsible for the change and if so, to what extent.
