oops I meant C
Does anyone have all the answers to Science 8B U3L7 STAAR Quiz for connexus?
oh... and how exactly is this algebra????????
Lady Unsane is right I got a 100% on my test thank you.
Yuh Duh
yeroooooooooooooo wassssup from 2021 !!! u know the vibezzzz
The correct answer is C. modify the area and allow larger and more complex organisms to appear.
To determine the correct answer, let's break down each option:
A. Change the area and make it safer from predatory organisms: While pioneer species do create changes in their environment, such as altering soil conditions or providing shelter, their primary role is not to specifically make the area safer from predators. This option is not entirely accurate.
B. Invade the area so that new organisms cannot be established: This option is incorrect. Pioneer species do not invade an area to prevent the establishment of new organisms. In fact, they pave the way for new organisms to colonize and establish themselves.
C. Modify the area and allow larger and more complex organisms to appear: This is the correct answer. Pioneer species, which are typically hardy and adaptable, initially colonize a barren or disturbed area. Through their presence and activities, pioneer species modify the environment, making it more hospitable for other organisms to establish themselves. Over time, larger and more complex organisms can appear and thrive.
D. Use up all the existing resources and prevent the establishment of non-native organisms: This option is incorrect. Pioneer species play a crucial role in preparing the environment for colonization; they do not deplete resources or prevent the establishment of non-native organisms.
To summarize, the correct answer is C. Pioneer species modify the area by altering conditions, allowing for the establishment of larger and more complex organisms as succession progresses.
