Limiting Factors: The Life Of A Duckweed

1120 Words5 Pages

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

    The average growing period (days between each molt) will be calculated for each sample. This will be calculated by adding the amount of days a newly molted milkweed bug appeared in the specific stadium up until more than 50% of the milkweed bugs are at that stadium. The days will then be averaged to find the average amount of days it takes for the milkweed bugs to develop into that stadium. The final data that we will collect is survivorship rates. This will be calculated by the amount of insects that stay alive throughout the experiment.

Healing spells are needed in everyday life, and if we were to ask someone how many healing spells they 've used in their lifetime, the number would probably be too high to remember. I also learned that mental illnesses are not one-spell-cure-all diseases, which is very helpful to know.

Different concentrations of Cobalt2+, Zinc2+ and Copper2+ as well as Co2+Cu2+ and Co2+Zn2+ were added to nutrients given to a species of duckweed, Lemna minor L. the effects of these metals on the growth of the duckweed was recorded. A change in growth was not very noticeable until the concentration of Cobalt (Co) and Copper (Cu) reached 2.00 ppm (parts per million), where the growth of the duckweed was inhibited. It was also discovered that Cu and Co work together to inhibit growth when they are at a certain concentration, and at other concentrations, the one would neutralise the other, creating less of an effect on the growth of the duckweed. The conclusion the I took from this study is that as the

    Water hyacinth is a plant species native to South America that has been introduced to some parts of the western United States, and has not ceased to wreak havoc since. The recent droughts in California have not seemed to help the situation, and the aquatic plant is a relentless pest that refuses to yield to any attempts at extermination. The state of California has spent millions of dollars in an effort to eradicate the invasive species, however water hyacinth shows no signs of leaving any time soon. Water hyacinth is a plant that is non-native to California, however it has been appearing in many of Northern California’s freshwater lakes and ponds. The plant floats on the surface of the water, and has thick, fibrous roots below the surface.

    There are no drastic spikes in the populations of any one species, or drops in another. A large number of different species (a great biodiversity) is one indicator of an ecosystem’s health. Remarkably, biodiversity is not necessarily dependent upon the size of the ecosystem; some of the richest ecosystems in the world exist within narrow boundaries (sections of the Amazon rainforest, for example, and the Galapagos Islands). These ecosystems might be relatively small, but besides threat from destructive human behavior, they’re strong because of their biodiversity; each species is connected to the other in some way. If a healthy ecosystem is one that is home to many different species, mostly native to the area and all interdependent upon one another, what’s an example of an unhealthy ecosystem?

    Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.

    As perceived in the graphs above there are indeed four different theoretical predator-prey relationships, where they could be differentiated by the difference in conditions of the predator and prey populations. In addition, one assumption that applies to the hypothetical predator-prey system is that the reproductive rate of the predators depends on the number of prey and predators available. Another significant assumption that could be taken into account is that the mortality of the prey specie depends on the population sizes of both the predator and prey species (functional response). According to the data used in lab, the stable oscillations (Figure 1) was crafted by imputing a median value of 0.04488 as the per capita predator mortality

    Introduction Overpopulation is the excessive population of an area to the point of overcrowding and it is an undesirable condition in every country where the number of existing human population rises to an extent exceeding the carrying capacity of ecological setting. Overpopulation can be result from an increase in births, an increase in immigration, a decline in mortality rates and other factors that may cause overpopulated environment. Therefore, this can cause influence as lack of the available essential materials for survival like water, shelter, social amenities and other because of the numbers of people might be more than the materials for survival. In such condition, this regularly contributes to environmental deterioration, worsening
