**Question:**Which statement about the classic competition experiments involving two Paramecium species is FALSE?**Options:**1. The experiment involved interspecific competition.2. The experiment involved exploitation competition.3. Each species, when grown alone, exhibited logistic growth.4. When grown together, the species exhibited logistic growth, but each reached a lower carrying capacity than when it was grown alone. (Selected as the false statement)**Explanation:**The false statement here suggests that when two Paramecium species were grown together, they both exhibited logistic growth but reached a lower carrying capacity than when grown alone. This implies that the competition between the species when co-cultured affected their maximum sustainable population size, which is contrary to the expected individual logistic growth patterns when species are not in competition.

The classic competition experiment often referred to in ecological studies involves the investigation of interspecific competition between two species, particularly using the example of Paramecium. This experiment is commonly associated with the pioneering ecologist G. Evelyn Hutchinson, who conducted studies on competition and ecological interactions.The false statement about the classic competition experiment involving two Paramecium species is:B. The experiment involved exploitation competition.In the classic competition experiment with two Paramecium species, the primary type of competition observed is interference or interspecific competition. Interference competition involves direct interactions between individuals of different species, such as resource depletion, territorial disputes, or interference with feeding.Exploitation competition involves indirect competition for shared resources without direct interactions between individuals. This statement is false because the experiment primarily focused on interspecific competition, which is a form of interference competition.The other statements are correct: The experiment involved interspecific competition: True, as the two Paramecium species were competing for shared resources.Each species, when grown alone, exhibits logistic growth: True, as logistic growth is a characteristic of populations that experience limiting factors. When grown together, the species exhibit logistic growth, but each reaches a lower carrying capacity than when grown alone: True, indicating that the presence of the other species affected the carrying capacity of each species due to competition for resources.The Exploitation competition experiment primarily focused on interspecific competition, which is a form of interference competition not exploitation competition.Hence,option 'The experiment involved exploitation competition' is false.
