Primary Succession Gradual growth of organisms in an area that was previously bare, such as rock. (For example lichens, mosses, and ferns will first appear on bare rock). The Following Steps: Secondary Succesion It is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat, (examples include areas which have been cleared of existing vegetaion such as a tree-felling in a woodland). Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine.
In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field. Compare && Contrast Primary Succession starts at bare rock. Secondary Succession starts with soil and dirt already there. Secondary Succession takes 100 +(plus) years to develop. Primary Succession takes thousands of years to develop.
The answer is resource
partitioning. Due to competition between the two species population, the
two species evolved to utilize different resources. Therefore, this is rather than competitive exclusion that results to the out-competition
of one species, or competition that results in
a negative interaction between the species.
<span>The phospholipid bilayer has a fluid makeup, so this allows vesicles to go from one part of the cell to another and fuse with those areas. The vesicles then go into these areas and deposit the needed substances or pick up waste products from these areas in order to remove them from the cell.</span>
