    community has adapted to live in a slightly different zone on the rocky shore, in order to avoid competition as much as possible. This is an example of Gause's principle; that no two species can have to same ecological niche, as one will always be better adapted, and soon wipe out the other. If there were, for example, to be a flood, then the high-tide organisms (such as the Brown-Barnacle and Blue-Banded-Periwinkle) could end up exposed to more wave action than they would usually experience as high-tide organisms. This wave action could pull them off the rocks, killing them, or the water would restrict their oxygen intake and they could drown. They would experience environmental factor levels they are not adapted to, exceeding their tolerance level, causing them to undergo physiological stress, and eventually perishing. This would cause many populations to decrease in size. The zonation pattern would be disrupted, and the community pattern may disappear altogether. However, the community pattern will return with time. This is because succession is taking place, as organisms replace each other and fall into their allocated niche in the community. The disrupted area has fewer species, with fewer defined zones as the different species have not had time to move into their different niches. Eventually we would expect the regenerating rocky shore community to return to the state it was before the disruption.…

    The evidence that corroborates competition is that the percentages were 57% and 58% which dictates that competition can explain cohabitation. Furthermore the competitive exclusion hypothesis states that no two species can occupy the same niche and coexist. In figure one, we can see that PcMix was starting to diminish because it cannot inhabit the same niche and would have continued to decrease until extinction. The niche structured is made up of resource continuum which leads to resource…

    survivorship; which death known is known to be greatest among the young. But in our ecosystem; type I survivorship are known to be typically exhibited by humans and elephants. But type III survivorship is known to be typically exhibited by many fish species. However, type II survivorship is known to be relatively rare in nature (For example, only a few species of lizards are known to be exhibited in this type of survivorship). 8. What is an ecological niche? In all ecosystems, an ecological…

    idea of an ecological footprint is becoming a popular topic among advocates of sustainability. An individual’s ecological footprint is the coined phrase that relates their use of the Earth’s natural resources to the amount of land needed to support their current lifestyle. When calculating ecological footprint, there are several different factors that are taken into account. These factors can range from the amount of locally grown foods consumed to the average number of miles driven on a daily…

    agricultural output as well as the ability for the ecosystem to absorb the waste that is generated by humans. Ecological Footprint on the other hand is how much area of biologically productive land and water is required per individual to produce all of the resources it consumes and to absorb the waste it generates. The biocapacity of a region is likely to change over time for many reasons. The first could be a change in climate. The more productive land is, the higher the biocapacity of the area…
