What is competition in ecology?
Explanation: The correct answer is C) The interaction where two organisms try to use the same limited resource. Competition in ecology refers to the struggle between organisms for limited resources such as food, water, or territory. Organisms that compete for the same resource may experience reduced access to the resource and increased competition for survival and reproduction.
What is resource partitioning?
Explanation: The correct answer is C) The division of limited resources among different species to reduce competition. Resource partitioning is a strategy used by different species to coexist and reduce competition for limited resources. It involves utilizing different parts of the resource or occupying different niches within an ecosystem to minimize direct competition and maximize access to resources.
Which of the following is an example of intraspecific competition?
Explanation: The correct answer is D) Plants of the same species competing for sunlight and nutrients. Intraspecific competition refers to competition between individuals of the same species. In this example, plants of the same species compete for essential resources like sunlight and nutrients, which are limited in the environment.
Which of the following is an example of resource partitioning?
Explanation: The correct answer is A) Two different species of birds competing for the same nesting sites. Resource partitioning involves the division of resources among different species to reduce competition. In this example, different bird species may occupy different parts of the habitat or use distinct nesting sites within the same area, reducing direct competition for nesting resources.
What is competitive exclusion?
Explanation: The correct answer is C) The elimination of one species from a habitat due to intense competition with another species. Competitive exclusion, also known as Gause's principle, occurs when two species compete for the same resources in a habitat, leading to the extinction or elimination of one of the species. The more efficient competitor outperforms the other, eventually excluding it from the environment.
