Ecology Is the Study of Nature and Living Organisms Research Paper

Table of Content

In the original Greek “oikos ” agencies, “house ” . So ecology is “the survey of the house ” the topographic point where you live, or the environment which technically includes all those factors, both nonliving and life, that affect an being. Ecology so is the survey of the interactions of beings in their environment includes both the life ( biotic ) and physical ( abiotic ) factors of the environment. It’s besides the scientific discipline, which formulates and trials hypotheses about environment. Ecology is the relationships, designation and analysis of jobs common to all countries. Ecology surveies the population and the community, evaluates cause and effects of the responses of populations and communities to environmental alteration.

The population is defined as an gathering of persons of a individual species that live in the same topographic point at the same clip. Besides, life scientists add an extra status: the persons in a population must interact with each other to the point of being able to crossbreed. Population is of import to understanding many of import ecological and evolutionary phenomena. Ecologists can utilize information from population ecology to foretell the success of a given species or gathering of species.

One property of populations that is observed in nature is their scattering, or the manner in which persons are distributed in a given country. Typically, life scientists refer to three types of scattering:

  • Clustered ( aggregated ) ,
  • Regular ( equally spaced ) ,
  • Random ( irregularly spaced )

Populations demoing a clustered form are common in nature and are found among many different types of beings. Clustered scattering forms are frequently due to environment heterogeneousness.

Regular scattering forms are comparatively rare in nature and occur when a resource is scarce. A good illustration of regular spacing occurs in animate beings that exhibit territoriality, a phenomenon in which animate beings set up an country for themselves and fight off all other single seeking to occupy that country. Regular scattering forms can besides be observed in workss. Random forms can be found in a assortment of beings ( trout in lake or maple trees in a wood ) .

Regardless of which organisms, the figure of births about ever has the potency to be greater than the figure of deceases. In other words populations of all species have the capacity to turn. That belongings is important importance to the success of all species. However, all species will non increase under all circumstance, but alternatively they can, given appropriate conditions. There are two theoretical accounts of population growing: the exponential theoretical account and the logistic theoretical account.

One of the most basic theoretical accounts of population biological science is the exponential growing equation, which is: ) N/ ) T = rmaxN This equation states that, in a turning population, the rate of alteration in population size is determined by the maximum intrinsic rate of addition ( rmax ) multiplied by the figure of persons in that population ( N ) .

If a population growing really rapidly we called that an exponential addition and its growing curve has a J-chaped called J-chaped curve. A population can non continue to turn indefinitely because this equation contains extra term called the carrying capacity ( K ) which is non fixed, but transporting capacity is invariably affected by many factors, both biotic ( populating ) and abiotic ( inanimate ) . The logistic population growing predicts that populations will turn quickly at first. However, as the figure of persons in the population ( N ) attacks the transporting capacity ( K ) , the population growing rate finally slows to zero, and the population stabilize at K.

The consequence is a sigmoidal or S-shaped curve which is frequently divided into three stages: the first is called the slowdown stage ( the period of slow growing that occurs when population Numberss are low ) . The 2nd is the log stage, which occurs when growing rate accelerates and becomes comparatively rapid. The tierce is the impregnation stage, during which population growing decelerates as N attacks K. All species have a chiseled life history that involves a beginning of life, a juvenile and generative stage and decease.

There are two of import parametric quantities of a population: survivorship ( how long one live ) and fruitfulness ( how many offspring one leaves ) . Survivorship is the figure still populating at the beginning of each age interval. The figure of deceases determines the decease rate during a given period of clip divided by the figure still life at the beginning of the clip period.


A community is an gathering of populations that interact with one another and the effects that they have on each other frequently greatly act upon their ability to last and reproduce. Because they are gatherings of different species, communities have belongingss that do them alone from single beings and populations. Some communities merely intermix bit by bit into others and for this ground are called unfastened remarks, forest communities are like that, as different vegetable types blend together. Conversely, closed communities have more definite boundary lines; few beings pass from one community to another. In these types of communities, fewer beings move in and out, so they are more stray in footings of energy and foods.

Despite the fact that communities can sometimes be hard to specify, ecologists have been able to place a batch of properties by which communities can be described and analyzed. Species composing which is the most cardinal property of a community. It’s merely a list of species of which the community is comprised. Communities vary enormously in their composing. Frequency is a step of how frequently we find a species in a community.

Distribution, or how species are arranged in a community. Diversity is a step of the fluctuation in a community, has two constituents. The first is profusion, which is the figure of species in the community. The 2nd constituent is called evenness, which is the grade to which the different species are represented in a community.  Stability is the construct of the ability of a community to manage perturbation or to defy being disturbed. It besides can mention to resilience of a community ( that is, its ability to retrieve rapidly from a perturbation. Certain communities can be called “delicate’which is used to mention to communities that have low stableness when faced with human perturbation. Competition involves a battle for limited resource.

Exploitative competition is the usage of the same resources in which one rival has greater entree than the other to the resources is. Interference competition is existent combat over resources. Intraspecific competition is between members of the same species and interspecies competition is between different species. The competition exclusion rule is that no two species can busy the same niche at the same clip. Because the niche of an being ( the manner in which it interacts with its environment ) is frequently dependent on how it fares in competition with its neighbours, both sort of competition is of import in the construction of the community.


Biome is defined as big, distinct and recognizable associations of life. More exactly, a biome is a peculiar array of workss and animate beings within a geographic country brought about by typical climatic conditions. Their works associations than those of animate beings, non merely normally place biomes more because the first is far more obvious, but besides because it determines the 2nd. Ecologists recognize about a twelve major biomes, each one signifiers under a certain prevailing clime and has a characteristic type of works and carnal life. Some illustrations of biomes include grassland, comeuppances, and deciduous woods. Biomes may be subdivided into communities.


For this paper, I read a batch of books and did a batch of research on Internet. I learned a batch about ecology, population, communities and biomes. It’s really difficult to compose about this topic in merely five pages. My first bill of exchange was constituted of eight pages so I cut a batch of inside informations. However, I pass a batch of clip to make this paper and energy and I truly enjoyed it. I hope it will be the same for you
