Duckweed is one of the smallest flowering aquatic plants and is present in fresh water or wetland habitats. Though it looks mundane, there is an intricate biological mechanism which is affected by factors such as limiting factors, carrying capacity, logistic and exponential population growth, density dependent and density independent limiting factors, competition, interspecific and intraspecific competition, and optimal growth conditions. All of these will be discussed in this essay to understand the life of a duckweed.

Populations can experience changes in size due to different factors, such as availability of resources and living conditions. Limiting factors, which are anything influencing the growth of a population, can restrict the size …show more content…

Interspecific competition occurs between two different species, while intraspecific competition occurs between individuals of the same species. Population Growth: Patterns and Processes of Human Population Dynamics. Limiting factors, or environmental stresses, such as nutrient limitation, water availability, and light intensity can prevent a population from reaching its potential carrying capacity. Carrying capacity is the maximum size a population can reach in a given environment in the absence of any additional factors. Logistic and exponential population growth differ in that exponential growth is the rate at which a population grows when resources are unlimited or available in moderate quantity, while a logistic curve adjusts the growth rate of a population as resources become limited and typically levels off once the population reaches its carrying capacity. Limiting factors, density-dependent and density-independent are both environmental stresses that can limit the size of a population. Density-dependent factors, such as resource availability, competition, and predation, increase as the population size increases, while density-independent factors, such as weather, fire, and natural disasters, are independent of population size and can limit the growth and survival of a population. Competition occurs when two species use the same limited resources, such as food or shelter, to meet their needs. Intraspecific competition occurs among members of the same species, while interspecific competition includes individuals of different species. With an appropriate understanding of the various factors impacting populations and strategies to control them to ensure sustainable growth, management strategies have the potential to be
