Two factors that influence succession are inhibition, in which one organism slows the growth of another, and facilitation, in which one organism aids the
growth of another. In the diagram, there are few grasses in softwood and
hardwood forests. How did these trees cause inhibition of grass growth?
A. O By limiting the amount of sunlight that reaches the ground
B. O By limiting the amount of water that reaches the ground
C.
By removing all of the nutrients from the soil
D. By removing all of the carbon dioxide from the air

this would be a math

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
