if a nutrient is in such short supply in an ecosystem that it affects an animal's growth, the

a. animal becomes a decomposer
b. substance is a limiting nutrient
c. nutrient leaves the food chain
d. ecosystem will not survive

The green house effect is

a. the result of an excess of carbon dioxide in the atmosphere
b. a natural phenomenon that maintans the earths temp range
c. the result of differences in the angle of the suns rays
d. an unnatural phenomemon that causes heat energy to be radiated back into the atmosphere


the unequal heating of the earth's surface

a.drives the wind and ocean currents
b. causes wind that transport heat throughout the biosphere
c.has importatn effect on earth;s climate regions
d. all of the above

which is a factor that could interrupt the progress of succession
a. colonization of sufraces by livhens
b. different animals appearing at each stage
c. another naural disturbance
d. long term fluctuations in climate
 
1.b
2.a
3.b ( I think)
4.This is a hard one. lichens don't matter so it's not A. Probably C because natural disturbances make it impossible for organism in an area to mate but D is also a natural disturbance so it's rather confusing.
 
if a nutrient is in such short supply in an ecosystem that it affects an animal's growth, the

a. animal becomes a decomposer
b. substance is a limiting nutrient-B is right
c. nutrient leaves the food chain
d. ecosystem will not survive

The green house effect is

a. the result of an excess of carbon dioxide in the atmosphere
b. a natural phenomenon that maintans the earths temp range-B again
c. the result of differences in the angle of the suns rays
d. an unnatural phenomemon that causes heat energy to be radiated back into the atmosphere


the unequal heating of the earth's surface

a.drives the wind and ocean currents
b. causes wind that transport heat throughout the biosphere
c.has importatn effect on earth;s climate regions
d. all of the above-D is right

which is a factor that could interrupt the progress of succession
a. colonization of sufraces by livhens
b. different animals appearing at each stage
c. another naural disturbance-I believe this one is correct 97% sure
d. long term fluctuations in climate
