What does population fluctuation mean in biology?
fluctuation in population size refers to the natural occurrence of brief population growth or decline. Such fluctuation does not necessarily indicate a problem. It may occur because of natural cycles, or as a response to an external stimulus. It can even be a part of an evolutionary process known as a population bottleneck.
What is population fluctuation in biology?
Population fluctuation refers to the natural changes in the size of species populations over time. It is a form of demographic variability which can have a positive or negative effect on an entire species. A decrease in population size can force a population to compete more intensely for resources and possibly lead to extinction. On the other hand, when an animal population grows too large for its local environment, it will tend to experience disease and starvation.
What does population fluctuation mean in biology examples?
Population fluctuation is related to the variations in the reproduction rate of a population. This can refer to how many offspring an animal has every year (longevity), the number of eggs an insect can lay (fecundity), or the number of plants that can grow in a particular area (reproduction). Fluctuation can occur over time due to natural environmental or evolutionary causes, and different species will vary in the way they respond.
What does population fluctuation mean in science?
Population fluctuation is typically studied in the context of ecology. Population fluctuation refers to temporary, short-term increases and decreases in population size, which occur naturally in a species’ population. These population fluctuations are often driven by species’ reliance on their environment and their interactions with other species within their environment. While many species of plants and animals can regulate their own population size, others are not so lucky. For example, if a species depends on a single food source, they are more susceptible
What does population fluctuation mean in biology mean?
Fluctuation in a population refers to changes in the size of a population over time. Population fluctuation is often caused by factors such as disease, natural disasters, or migration. Fluctuation doesn’t always mean a decrease in population. If the population of one species increases, the population of another species may decrease. Even if the overall population of a species remains constant, the population of a specific sub-population can change.
