primary and secondary successsion
invasion of exotic species
increase in mean annual temperature and a decrease in mean annual precipitation
an increase in both mean annual temperature and mean annual precipitation
an increase in total annual hours of sunlight

oxidation of sulfur by bacteria in ocean vent communities
photosynthesis by phytoplankton
respiration by zooplankton
Which of the following best describes soil in many tropical rain forests?
They are permanently frozen
They are nutrient rich due to leaf litter from winter
They are identical to grassland soils

mutualism
parasitism
predation
Exemplified by bees consuming nectar and carrying pollen from one flower to another
commensalism
mutualism
competition
predation

occurs in mutualisms.
can occur through morphological differences between competing species.
can cause the extinction of a competing species.
is not the result of behavioral changes
