For example, you cannot raise 4,582 tomato plants in the area of a telephone booth. Nor can 712 guppies survive happily in a small fishbowl. The reason for this is that resources such as space, nutrients, and water are limited and this will automatically result in the process called competition. Competition occurs when organisms have an adverse effect on each other as a result of requiring the same resource.
Competition occurs between two or more organisms.
When these organisms belong to the same species it is referred to as intraspecific competition . When it occurs between individuals of different species it is interspecific competition . The goal of this lab is to measure the intensity of competition using a group of plants in the genus Brassica . These plants belong to the family Brassicaceae that contains the common mustard and radish plants. One reason is that these plants respond quickly to artificial selection during domestication.
