Front 1

What attributes make lifre differ from nonlife?

Back 1

>organizes matter.
>uses energy to perform useful work.
>uses energy to create temporary order within itself.

Front 2

Life requires energy

Back 2

to accomplsih useful work-the processes of life.

Front 3

True or False:
The second law of thermodynamics says that with the passage of time, disorder increases.

Back 3

True

Front 4

True or False:
Although mattter exists in a low-entropy state within an organism, it is local and temporary, and requires more energy to create than it retains.

Back 4

True

Front 5

True or False:
Heterotrophy refers to those organisms that must get their energy from other organisms.

Back 5

True

Front 6

Cellular respiration is

Back 6

the conversion of carbohydrates to useable energy.

Front 7

Primary producers are

Back 7

the organisms that create energy-rich compounds.

Front 8

True or False:
Photosynthesis is the process of converting light-energy in to carbon dioxide.

Back 8

False

Front 9

True or False:
Photosynthesis is the prodction of high-energy compounds from light and low-energy compounds. Respiration is the release of energy from high-energy compounds as they convert into low-energy compounds.

Back 9

True

Front 10

True or False:
Chemosynthesis is similiar to photosynthesis because it uses sunlight, but different because it does not produce carbohydrates.

Back 10

False

Front 11

Back 11

carbon, grams per square meter of surface per year

Front 12

Biomass means ___________ . Standing crop is the ________ in an ecosystem.

Back 12

mass of living tissue, mass of living tissue at a given time

Front 13

True or False:
The primary production of land is higher than the primary production of the sea, but the sea's primary production is much more efficient.

Back 13

True
