The ability of organisms to regulate and thus maintain a relatively stable internal environment, despite external pressures, is called HOMEOSTASIS. This word comes from two Latin/Greek root words: "homeo" and "stasis".
"Homeo" means constant or unchanging. And "stasis" or "static" refers to stillness, non-movement. So, together, we can translate Homeostasis into a constant stillness inside, which makes sense for "maintaining normal internal states."
host can be considered to be an ecosystem in that it is an environment containing a diversity of entities (e.g., parasitic organisms, commensal symbionts, host immune components) that interact with each other, potentially competing for space, energy, and resources. the url code https://www.sciencedirect.com/science/article/pii/S1471492215000409
Answer:
The correct answer would be B an increase in predation.
Predation is one of the many biological interactions in which one organism is benefited and other is harmed. In this interaction, one organism kills the other one to get nutrition out of it.
The one who kills is known as predator and the one who is killed is known as prey.
In nature, mice serves as a prey for many organisms such as snake, owl, hawk, cat, dog etc. Hence, there are concrete chances of increased predation of mice in an area.
Other reasons for the decrease in a population of any organism in nature can be: increased competition, habitat destruction, mutation, new disease or fast rate of transmission of disease etc.
