Answer:
Allergens differ from antigens because *they do no stimulate the immune system resulting in the production of leukocytes rather than the stmulate the IgE antibodies*
Explanation:
Allergen and antigen are both foreign substances that can cause certain disorders to animals, but there is some difference between them in terms of their nature and the diseases caused by them. An allergen is a nonparasitic foreign substance that can cause certain immune reactions in the body when it enters the body. Whereas, an antigen is a foreign substance that can trigger the immune system to produce a specific immune response. This immune response leads to produce antibodies that can neutralize or destroy the foreign substances that entered the body.
Allergens can produce Systemic Allergic Response. Allergens stimulate the IgE antibodies by binding to them on the mast cells and causing the mast cells to rupture and release histamine, serotonin, and heparin, initiating inflammatory response.

Explanation:
Population study in ecology is a broad topic to be studied, in order to answer this question we must know that .......
<h3>
Population
</h3>
A population, in Ecology, can be defined as a set of individuals of the same species that live in a given area in a given period of time. Individuals in one population are more likely to interbreed with each other than with organisms in another population of the same species.
<h3>
Population dynamics</h3><h3>
</h3>
Population dynamics is the study of how and why populations change in size and structure over time. Important factors in population dynamics include rates of reproduction, death and migration.
With this information, we can say that" Ecologists conduct population studies to understand population dynamics by investigating how the <u>number of individuals</u> increases or decreases over time.
<u />
<u>We can conclude that these studies in </u><u>Population dynamics </u><u>are of great relevance to visualize the characteristics of </u><u>populations</u><u>.</u>
