Answer 1

Answer:

Explanation:

Two species of Paramecium were placed into flasks with a bacterial culture used as food source (Gause, 1934). Both species were thus forced to share the same niche in this microcosm. Through a daily count of the Paramecium number, a pattern became evident to Gause: a few days after, one species always became extinct, as apparently it was unable to compete with the other species for the single food resourceGause (1934) placed two species of Paramecium into flasks containing a bacterial culture that served as food. Thus, in this artificial laboratory system both species of paramecium were forced to have the same niche. Gause counted the number of Paramecium each day and found that after a few days  one species always became extinct because it apparently was unable to compete with the other species for the single food resource.

Answer 2

Gause's experiment on Paramoecium is associated with the phenomenon of competitive exclusion.

• It is also referred to as the Gause's law.
• According to the experiment, any two species which are competing for the same limited resource cannot coexist at constant population values.
• In other words, competitors cannot live together.

• Experiment:

• Gause used two species of Paramecium, P. caudatum and P.aurelia for the experiment.
• He kept adding fresh water daily and a constant supply of food.
• P. caudatum was found to dominate initially but P. aurelia subsequently suppressed the growth of P. caudatum. This is due to the exploitative resource competition.
• However, Gause altered the conditions and let P. caudatum survive by changing certain environmental parameters such as water and food.
