What is the Definition of Population in Biology? Show
Answer – In biology, a population is defined as a group of individuals of the same species living in a particular region at the same time.Explanation: For ease of research, every ecosystem is organized into a number of levels. From the smallest, the levels are individual, population, community, ecosystem, biome, and biosphere. A population refers to all individuals of a particular species that live in a defined area at the same time. For example, human beings are a species scattered across the world. However, only those living in a specific region, like say New York City, comprise a population. Thus, one species makes up several populations, with each population including only some members of a species. Populations vary over time with births and deaths. They are also impacted by the displacement of individuals to/from other geographic regions due to changes in resource availability and environmental factors. Further, the growth of a population can be supported by its environment only till it reaches the carrying capacity. This is the maximum size beyond which the population cannot grow. Popular Questions
Which of the following best predicts the impact on the lizard species?Which of the following best predicts the impact on the lizard species if there is a gradual increase in the average temperatures found in both the lowlands and mountains in this region? Some lizards will migrate to new habitats in the mountains and become isolated, leading to allopatric speciation.
Which of the following best predicts a long term effect of the differences between E and Z strains?Which of the following best predicts a long-term effect of the differences between the E and Z strains? The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Which of the following best predicts the effect of the enclosure on the O'Neill population?Which of the following best predicts the effect of the enclosure on the O'Neill population? The frequency of the MC1RDMC1RD allele will decline due to natural selection.
Which of the following is the best prediction of how the new disease will affect the two populations?Which of the following is the best prediction of how the new disease will affect the two populations? (C.) The smaller population will be more affected than will the larger population, because the smaller population has less genetic variation than the larger population has.
