Short Essay on Parasitism (2141 Words)

Here is your short essay on Parasitism !Parasitism is a kind of harmful coaction (disoperation) between two species. It is the relation between two individuals wherein one individual called parasite receives benefit at the expense of other individual called host. Parasitism is mainly a food coaction, but the parasite derives shelter and protection from the host, as well. image source: creationrevolution.com ADVERTISEMENTS: A parasite usually parasitizes a host which is larger in body size than it. Further, a parasite does not ordinarily kill its host, at least not until the parasite has completed its reproductive cycle. However, a host may die due to some secondary infection or suffer from stunted growth, emaciation, or sterility.The balance between Parasite and host is upset if the host produces antibodies or other substances which…

Essay on Predation : Components & Effects

Fashion

Here is your Essay on Predation : Components & Effects !Predation is a form of disoperation, at least in point of immediate effects, since one animal kills another animal or plant for food Like parasitism, predation is important in community dynamics but both differ in the point that a predator tends to be large than its and it catches its prey from without, while a parasite is smaller than its host and consumes it from within. image source: arctictundraproject.files.wordpress.com Components of predation: The main components of predation are predators and prey. A successful predator has following characteristics: ADVERTISEMENTS: 1. The hunting ability of a predator remains well developed.2. By their hunting activities predators can be regarded as specialized or generalized. Specialized predators are those adapted to hunt only a few…

Short Essay on Ecological Succession (743 Words)

Ecosystem

Here is your essay on Ecological Succession !As a lake fills with silt it changes gradually from a deep to a shallow lake or pond, then to a marsh, and beyond this, in some cases, to a dry-land forest. When a crop field is deserted or a forest is severely burned over, it is just like a plot of bare ground and a series of plant communities grow up there and replace one another— first annual weeds, then perennial weeds and grasses, then shrubs, and trees—until a forest ends the development. image source: fda7ed3288f75266dcf2-c3155e3c451bb708de9594bb4903715e.r46.cf2.rackcdn.com ADVERTISEMENTS: Likewise, if a landslide exposes a surface of rock in the mountains, the surface may be successively occupied by a sparse cover of lichens; a spreading moss mat; grasses, which enter and become a meadow;…

Short Essay on Tundra Bioma (485 Words)

Essays

Here is your essay on Tundra Bioma !Tundra presents the most common example of “fragile ecosystem” (Clapham, Jr., 1973). Tundra which means “marshy plain”, lies largely north of latitude 60°N (i.e., between the Arctic ocean Mid polar ice-caps and the forests to the south) and is characterized by the absence of trees, the presence of dwarfed plants, and an upper ground surface that is wet, spongy and uneven, or hummocky, as a result of freezing and thawing of this poorly drained land. (Kormondy, 1976). image source: 435729.medialib.glogster.com ADVERTISEMENTS: Some five million acres of tundra stretch across Northern America, Northern Europe and Siberia. Although there is variation from place to place within the biome, temperature, precipitation, and evaporation are characteristically low, the warmest months averaging below 10°C and the wettest with…

Essay for kids On Energy (500 Words)

Ecosystem

Here is your Essay for kids On Energy !Energy can be defined as the capacity to do work, whether that work be on a gross scale as raising mountains and moving air masses over continents, or on a small scale such as transmitting a nerve impulse from one cell to another. There are two kinds of energy, potential and kinetic. Potential energy is energy at rest. It is capable of and available for work. image source: lettherebeneon.com ADVERTISEMENTS: Kinetic energy is due to motion, and results in work. Work that results from the expenditure of energy can both store energy (as potential energy) and arrange or order matter without storing energy.The expenditure and storage of energy is described by two laws of thermodynamics. The first law of thermodynamics called law…

Essay on Overlapping Niches and Niche Separation (468 Words)

Relationships

Essay on Overlapping Niches and Niche Separation !Though two populations cannot coexist in a given habitat with precisely the same niche, it is highly probable that the niches of different populations will show varying degrees of overlap. image source: inman.com ADVERTISEMENTS: This occurs when two organisms use the same resource, such as food. Thus the concept of the niche is closely associated with the concept of competitive exclusion and competitive relationships among spices (see chapter 16).Basically, Gause Principle or competitive exclusion theory states that no two species persist in the same niche. Either one becomes extinct, through natural selection; diverge into different niches. The latter phenomenon is called niche separation. Consider, for example, two species of plants that are able to grow in saline water, as in salt marsh.Species A…

Short Essay on Mutualism (372 Words)

Essays

Here is your Essay on Mutualism for School and College Students!Mutualism is an obligatory interaction that is strongly beneficial to both species. The term symbiosis has often been applied to this relationship (i.e., mutualism), but symbiosis properly refers to intimate association of two or more dissimilar organisms, regardless of benefits or the lack of them and hence includes mutualism, commensalism and parasitism (see Smith, 1974). image source: 12d38d224c2abe5fa63a-1db4ec0fed747b962fac0a483e2c9d9e.r18.cf2.rackcdn.com ADVERTISEMENTS: Mutualism may be facultative, when the species involved are capable of existence independent of one another, or obligate, when the relationship is imperative to the existence of one or both species.Mutualism in plants is demonstrated in the association of fungi and algae to form lichens, of nitrogen-fixing bacteria with the roots of legumes, and of fungal mycorrhizae with the roots of…

Essay on Adaptations and Ecotypes (712 Words)

Environment

Here is your Essay on Adaptations and Ecotypes !Organisms can respond to environmental stress in such a way that their tolerance zones may change. The genetic changes that occur during the evolution of the species because of mutation and natural selection are called adaptations. image source: margaretnoble.net ADVERTISEMENTS: Presumably, each species is fairly well adapted or fit, if it has been in its particular environment for many generations. The range of tolerance of a species may be narrow (i e., species has a low ecological amplitude) or broad (i.e., species has a high ecological amplitude).Thus, organisms are “slaves” to the physical environment; they adapt themselves and modify the physical environment so as to reduce the limiting effect of temperature, light, water and other physical conditions of existence. Such factor compensation…

Short Essay on Population Density (436 Words)

Sociology

Here is your essay on Population density !The density of a population refers to its size in relation to some unit of space on observed time. The size of the population can be measured in several ways, including abundance (absolute number in population), numerical density (number of individuals per unit area or volume), and biomass density (biomass per unit area or volume). image source: healthcatalyst.com ADVERTISEMENTS: The density of a species population can be expressed either with reference to total area (crude density) or with reference to the actual area of habitat available to the species (ecological density).Thus, we might have a crude density of 500 rabbits per square mile but if only half of the square mile had suitable habitat for rabbits, the ecological density would be 1000 per…
