macroclimates

Answer 2

weather conditions that reoccur on the regional landscape, and/or a global scale

Question 3

microclimates

Answer 3

weather conditions that reoccur on a smaller scale, (such as, within a forest, or under a rock)

Question 4

ecology

Answer 4

scientific study of the interations between organisms and the living and nonliving components of their enviornment

Question 5

ecology deterimines the distribution:

Answer 5

of organisms and their abundance

Question 6

Every enviornment is characterized by differences in:

Answer 6

abiotic and biotic factors

Question 7

abiotic factors

Answer 7

non- living factors such as light, temperature, water and nutrients.

Question 8

biotic factors

Answer 8

living factors, other organisms that are a part of an individual’s enviornment.

Answer 9

solar energy and Earth’s movement in space

Question 10

tropics

Answer 10

the place with the most intense sunlight, direct sunlight(23.5 N- Lat and 23.5 S- Lat)

Question 11

If a mineral nutrient;s outpuits exceed its input:

Answer 13

it will limit production in that system

Question 14

Answer 15

autotrophs

Question 16

primary consumers

Answer 19

prokaryotes and fungi

Question 20

detrivitores or decomposers get energy from

Answer 20

nonliving organic matter(detritus)

Question 21

nutrients cycle through an ecosystem

Answer 21

true

Question 22

primary productivity

Answer 22

the amount of light energy converted to chemical bond energy(inorganic molecules to biomass) through photosynthesis during a given time period

Question 23

gross primary production(GPP)

Answer 23

total primary production

Question 24

net primary production(NPP)

Answer 24

GPP minus energy used by autotrophs for respiration. usually 1/2GPP

Question 25

net ecosystem production(NEP)

Answer 25

measure of the total biomass accumulation of producers and consumers during a given period. GPP- (respiration of all organisms) - estimated by comparing the flux of CO2 and O2
