Answer:
To avoid the ethical issues a true experiment would cause.
Explanation:
A quasi-experiment is a factual conventional study that is used to calculate the causal effect of interference on a target population without an irregular function. Quasi-experimental research shares closeness with traditional experimental design or randomized controlled trials, but lacks the element of random assignment specifically for treatment or control.
Instead, quasi-experimental designs typically allow the researcher to control the assignment to treatment status, but use some criterion other than random assignment (For example- an eligibility cutoff mark).
Answer:
Matching the theories to what the theories proposed:
✔️Multiple factors impact the climax community ➡️polyclimax theory
✔️The entire environment impacts the climax community➡️climax pattern theory
✔️Only climate impacts the climax community➡️monoclimax theory
Polyclimax theory: This proposes that there are more than one vegetation climax. It is controlled by soil moisture, topography, fire and activities of animal.
Climax pattern theory: This theory proposes that the species structure, ecosystem and balance of the climax are determined and impacted by the entire and total environment found in the ecosystem.
Monoclimax theory: This proposes that only climate impacts the climax community. It identifies that every region actually has one climax community. It's by it all communities are developing.
