Both primary and secondary succession have pioneer species that-??
A--change an area to make it safer from predatory organisms
B--invade the area so that new organisms cannot be established
C--modify the areas to allow larger, more complex organisms to appear
D--use up all the existing resources and prevent the establishment of non-native species
here
There are two types of succession. The first is primary succession. ... The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.
the answer is , i think, D
all u did was look it up I tried that already but what the answer a b c or d

C--modify the areas to allow larger, more complex organisms to appear
Both primary and secondary succession involve pioneer species that modify the environment in order to create conditions more suitable for the establishment of larger and more complex organisms. These pioneer species, such as mosses or lichens in primary succession, or grasses and shrubs in secondary succession, play a crucial role in preparing the ground for other organisms to colonize.
To arrive at this answer, let's go through the options:
A--change an area to make it safer from predatory organisms: This is not true for both primary and secondary succession. While some changes may occur that indirectly affect the presence of predatory organisms, it is not the primary purpose of pioneer species in either type of succession.
B--invade the area so that new organisms cannot be established: This is also not the purpose of pioneer species. Their role is to create conditions that facilitate the establishment of new organisms, rather than preventing it.
C--modify the areas to allow larger, more complex organisms to appear: This is the correct answer. Pioneer species modify the environment by breaking down rocks, adding organic matter, and stabilizing soil, which improves the soil quality and allows larger and more complex organisms to thrive.
D--use up all the existing resources and prevent the establishment of non-native species: This is not true for pioneer species. While they may utilize some existing resources, their goal is not to deplete them but rather to prepare the environment for other organisms. Additionally, pioneer species do not actively prevent the establishment of non-native species; their role is to create conditions suitable for new organisms, regardless of their origin.
Therefore, the correct answer is C--modify the areas to allow larger, more complex organisms to appear.
