Answer:
Secondary succession
Explanation:
Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.
Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.
Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.
Answer: Local chemical conditions
Explanation: A Precapillary Sphincter is a smooth muscle that is located in circles around the capillaries.
The precapillary sphincter helps to coordinate blood flow to the into the capillaries by causing the capillaries to decrease the flow of blood to tissues that are dormant or not active.
Stratification in the field of ecology refers to the vertical layering of a habitat; the arrangement of vegetation in layers. ... strata) of vegetation largely according to the different heights to which their plants grow. The individual layers are inhabited by different animal and plant communities (stratozones).
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
<em> A. </em><em><u>Eyepiece</u></em><em> is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>
<em> C. </em><em><u>Coarse Adjustment </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>
<em> D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
