According To The Competitive Exclusion Principle, Two Species Cannot Continue To Occupy The Same

Competition is one of the biggest factors affecting species. Species compete with each other for resources, such as food and space.

If one species has a limited resource and another species requires that resource, there will usually be competition over that resource. If one species outgrows its resource needs, it can eventually eliminate the need for that resource, which can lead to interspecies cooperation.

Scientists have found that when two competing species are in an eternal struggle for resources, they may not be able to coexist forever. According to the Competitive Exclusion Principle (Cep), if two competing organisms reach an equilibrium where neither one can outcompete the other, then one or both of them will go extinct.

This happens because when two similar organisms reach an equilibrium, neither one can change in order to survive. For example, if two similar plants both rely on the same amount of water and sunlight to survive, then one plant cannot adapt to use less water or sunlight to outlive the other plant during a drought.

Two species cannot continue to occupy the same area

This principle was first stated by German biologist Ernst Haeckel in the early 20th century. He stated that “two species cannot coexist at the same time in the same place,” and that this idea applies to species that could potentially interbreed.

This principle has been expanded to include all species, not just those that could interbreed. All species of animals, plants, and other organisms cannot continue to occupy the same area at the same time.

The Competitive Exclusion Principle states that one of the species will eventually go extinct if the two continue to interact. One of them will either move away or become extinct due to inability to compete with the other species.

This principle can be applied on a smaller scale, as well. Two similar species that occupy the same area cannot continue to do so- one will eventually leave or die out.

One species will go extinct

According to the competitive exclusion principle, one species will go extinct when the two species cannot coexist. This happens when a species cannot find a suitable habitat or enough resources to survive.

For example, if two species of trees could not grow together due to limited space or soil type, then one of the trees would eventually die off. The other tree could continue to grow, but only at the expense of the other tree.

The same goes for any animals that depend on trees for shelter and food. If one tree could not provide enough of these necessities, then all of its inhabitants would perish.

The competitive exclusion principle is an important concept to understand when considering how climate change will impact wildlife. As temperatures rise and climates shift, new species may come into territory already occupied by another species.

The winner takes all

The concept that one species can drive another species to extinction is a terrifying thought. But it happens more often than you might think.

According to the Competitive Exclusion Principle, two species cannot continue to occupy the same area without one species driving the other to extinction.

This was famously demonstrated with lab mice. When scientists tried to keep two types of mice in the same cage, they eventually died. The surviving mouse appeared healthier and happier as a result.

The same phenomenon has been observed in wild animals as well as plants. In fact, this principle has even been named after it: The CEP, or Competition Equilibrium Principle, was first established by American ecologist Raymond Pearl in his 1932 book Physiological Economy in Animals and Plants. He later refined his definition of the CEP in his 1939 book Nature’s Law: A Psychological and Biological Theory.

Examples of the principle in action

The principle was first postulated by American ecologist Robert T. Peters in 1974. He based his idea on the observation that when two species attempt to occupy the same ecological niche, one of them will be forced to change its habits or habitat in order to survive.

Over time, this can lead to one species’ total extinction. For example, if wolf populations grow too large, they will begin to hunt prey species with greater ease and thus increase their population size. This will cause prey species populations to decrease, which will eventually cause wolf populations to decrease as well.

Another example is the introduction of non-native species into an environment. If two species cannot coexist in the same area, then one of them will eventually be driven out or killed off due to the other’s presence. Non-native species are often particularly successful at driving out native ones because they don’t recognize the threats they pose.

Yet another example is human activity such as pollution and habitat destruction. These activities can drive out certain species, but cannot completely eliminate them completely.

Applications of the principle

The Competitive Exclusion Principle has wide applications in both research and everyday life.

In research, the principle is used to explain why some species become extinct while others survive. By identifying the factors that influence competition between species, researchers can better understand how to protect endangered species.

In everyday life, the principle explains why you should try to diversify your investments. If you invest all of your money in one company, for example, they may go out of business and take your money with them.

You should invest in different companies so that if one company goes out of business, you have still gained value in the other ones that you invested in.

Similarly, different species can coexist but only if they are not too similar. If two species occupy similar ecological niches then they will eventually reach a point where one cannot survive because of the other.

The principle does not always hold true

While it may seem like an iron-clad law of nature, the Competitive Exclusion Principle is not a universal truth. In fact, scientists have found cases where species have coexisted despite competing for the same resources.

In these cases, the species either evolved to use different resources or they evolved in such a way that they no longer competed for the same resources.

For example, two species that compete for the same food or habitat can evolve such different nutritional requirements that one does not compete for the other’s food source. Or, one species can evolve such strong defenses against the other species that there is no competition.

Another case where the principle does not hold true is when a new species emerges and has no competitors, thus allowing it to thrive. These new species can then either eventually cause other species to go extinct or vice versa depending on whether they compete or not.

Implications for humans

While the concept applies to all species, the term was coined in reference to animals. However, the principle can be applied to humans as well.

For example, it is believed that several factors contributed to the demise of Western civilization, including environmental destruction and the collapse of the middle class.

These may have been caused in part by competition for resources such as oil and gas, which are needed to run vehicles and factories.

By understanding this principle, you can prepare for potential crises that may reduce your ability to obtain essential resources. For example, you could invest in renewable energy sources like solar or wind power so that you will still have access to them in the future.

This also applies to social interactions: By recognizing competition between groups and strategies for overcoming it, you can ensure your wellbeing in the long run. This includes recognizing competition within your own group—such as between individuals or between communities.
