Is it true that an introduced species can drive an invasive species to extinction?

Yes, for example: Say someone brought a type of fish (cod maybe) to Alaska that does not naturally live there. Then the cod spreads to salmon spawning grounds. So you have large hungry cod against baby salmon, who wins? The cod right. So the cod eats eventually all the baby salmon. This is not the best example but in a long while the salmon numbers will go down

Then with not enough to reproduce you have no more salmon. Still don't get it? Look below
Hungry big cod+ little baby samon= less to reproduce= less babies which are eaten

Yes, an introduced species can outcompete and displace an invasive species in some cases, leading to its extinction. This can happen if the introduced species has a competitive advantage or if it preys on the invasive species, disrupting its population dynamics. However, it is not always guaranteed as invasive species can also adapt and thrive in new environments.

When two species use the same resource one species may drive the other to extinction?
This is a phenomenon known as competitive exclusion, where one species outcompetes the other for resources such as food or habitat. It can lead to niche differentiation, where the competing species evolve to occupy different niches to coexist. This competition can be a strong driver of natural selection.
Why is the dinosaur extinction significant?
The dinosaur extinction is significant because it led to the demise of the dominant species on Earth at the time, paving the way for mammalian evolution and eventually the rise of humans. It also provides important insights into how environmental changes can impact ecosystems and drive mass extinctions.
Is it true Climate changes have been linked to almost all mass extinctions of life on Earth?
Yes, there is scientific evidence linking climate changes to many mass extinction events in Earth's history. Shifts in climate, such as ice ages or warming periods, can disrupt ecosystems, drive changes in species distribution, and lead to extinction events. The most well-known example is the Permian-Triassic extinction, which was likely triggered by volcanic activity causing a massive release of greenhouse gases.
What is an example of competitive exclusion principle?
An example of competitive exclusion principle is when two species compete for the same limited resources, one species will outcompete the other and drive it to extinction in a specific ecological niche. This principle helps explain why only one species typically dominates in a given niche.
What is the reason that no two similar species an occupy the same niche?
The short answer is that one is always going to be slightly better at that exact niche than the other, and so will drive the competitor to local extinction. In reality, two species in nearly the same niche will often co-occur, but there will be more resources in a very similar niche that will allow for one species to exploit those other resources. Evolution can happen very quickly in these high competition areas (in a matter of a few years, it has been directly measured).
How does non-native and invasive species impact population size?
Non-native and invasive species can impact population size by outcompeting native species for resources, preying on native species, disrupting ecosystem dynamics, and spreading diseases. They can lead to declines in native populations by altering habitats and food availability. In some cases, invasive species can even drive native species to extinction.
What is an introduced species and how can such species affect native plants and animals?
An introduced species is a species that is not native to a particular area but is brought there by human activities. These species can have negative impacts on native plants and animals by outcompeting them for resources, predating on them, or introducing new diseases that the natives are not equipped to handle. This can lead to declines in native populations and disruptions in the ecosystem.
How does extinction drive evolution?
A mass extinction event creates a large gap in the biodiversity of an ecosystem or multiple ecosystems, which results in a rapid period of evolution of a range of different species that weren't particularly specialised to fill that niche.
What is often the result of direct competition in nature?
Direct competition in nature often leads to the survival of the fittest, where only the strongest individuals or species are able to thrive and reproduce. This competition can drive evolutionary adaptations that help organisms better compete for limited resources such as food, mates, or territory. Ultimately, it can lead to the extinction of less competitive species.
Why do organisms go for extinction?
1) because of the people destroy their homes. 2) because of the people who kills them. 3) because of the other carniverous animal eat the other animal for them to have food in order to survive
How does taking animals for profit affect extinction?
Taking animals for profit can lead to overexploitation and depletion of wild populations, pushing species closer to extinction. It disrupts ecosystems by removing key components, impacting food chains and biodiversity. Additionally, illegal wildlife trade for profit can drive species towards extinction more rapidly due to high demand and unsustainable harvesting practices.
Why have some endangered aquatic species already become extinct?
Because of our pollution, and how we hunt them as well of lack of food source because of again us , as well their predators may have grown in population again helping drive the species to extinction. and with our growing population only more and more animals as well as aquatic animals will be driven to extinction
Why is an introduced species bad for the community?
Introduced species can negatively impact ecosystems by outcompeting native species for resources, spreading diseases, and disrupting natural food chains. They may also lack natural predators in their new environment, causing their populations to grow unchecked and potentially leading to the decline or extinction of native species.
Why may a species become extinct?
Here are some reasons that some species become extinct: Thyllacine, the "marsupial wolf" was hunted into extinction, as was the passenger pigeon and probably the moa. Competition for resources can drive species into extinction. Disease and predators also take their toll. Insecticides like DDT weaken bird egg shells so that fewer of them hatch. Loss of habitat is yet another factor.
When two species use the same resource one species may drive the other to extinction?
This is a phenomenon known as competitive exclusion, where one species outcompetes the other for resources such as food or habitat. It can lead to niche differentiation, where the competing species evolve to occupy different niches to coexist. This competition can be a strong driver of natural selection.
Should hunters be able to hunt all land animals?
No! This could seriously decimate populations of threatened animals and drive many species to extinction. For this reason, in many countries hunters are required to have hunting permits, and certain species of animals can only be hunted at specific times of the year.
What animal did the railroads nearly drive to extinction?
The animal that the railroads nearly drove to extinction was the Buffalo. The railroads severely destroyed the buffalo's natural habitat.
