How are oceans being impacted by invasive species
they kill most of them
The guby fish likely became invasive by being introduced to new environments where it had no natural predators. This allowed the guby to reproduce rapidly and outcompete native species for resources, disrupting the balance of the ecosystem. Additionally, human activities such as accidental releases or aquarium pets being released into the wild can contribute to the spread of invasive species.
Invasive species have such an impact on the environment because they basically have no naturally known enimies. If they come from a different land, the organisms that are already living there aren't used to the envasive species being there, and have no natural defense against them. The invasive species will devour all it wants, and can wipe out an entire population of a species in an area.
Selection pressure caused by the invasive species entering the ecosystem. They would be possibly competing for the same resources with different traits that might favor one species traits over the others on average. The native species is a population of variants, so some among the native population could compete with the invasive species on a more equal footing. These would be naturally selected by being reproductively sucessful, ultimately, and thus change the allele frequency in the native populations gene pool; the definition of evolution.
Ruffe fish, native to Europe and Asia, have become an invasive species primarily in the Great Lakes region of North America, particularly in Lake Superior. Since their introduction in the 1980s, they have outcompeted native species for resources, disrupted local ecosystems, and posed threats to commercial and recreational fisheries. Their rapid reproduction and adaptability have made controlling their population challenging. Efforts to manage their spread include monitoring and potential removal strategies.

Some invasive species in the Everglades include Burmese pythons, Brazilian pepper trees, melaleuca trees, and Old World climbing fern. These species outcompete native plants and animals, disrupt the natural ecosystem balance, and pose a threat to the Everglades' biodiversity. Efforts are being made to control and eradicate these invasive species to protect the unique environment of the Everglades.
Some endangered animals are being held in captivity which provide them with food, water, toys and more species that they can play with. Endangered animals are also being trained to protect them selves so when they are fully grown and have been put to their natural habitat, they can protect them selves from wild species and not get hunted by humans.
They can affect the chemical makeup of the water, availability of resources, and even alter the food web. Invasive species impact other species more directly through competition for resources. Because invasive species evolved with other competitors and native species evolved in the absence of invasive species they lack the ability to compete with invasive species. They are costly to society in many ways through both, direct management, and decreased production. The annual estimated cost in the United States of invasive species control is about 120 billion dollars per year. It is estimated that the global cost of invasive species management is equal to five percent of the global economy.
In the US, Zebra mussels have been specifically targeted by the National Invasive Species Act (NISA) of 1996, which includes an Invasive Species Task Force. The Act itself officially authorizes the regulation of ballast water, for one... Please access the related link listed below for more information.

Eastern Red Cedar. Had to find the answer for a Bio class
The original species are not used to the new predators being in their environment, so they will become endangered and the new species will dominate.
Some invasive species that can be found on Mt Everest include the Himalayan blackberry (Rubus armeniacus) and the Himalayan knotweed (Persicaria wallichii). These species have been introduced to the region and outcompete native plants, disrupting the natural ecosystem. efforts are being made to control and manage these invasivespecies to protect the local biodiversity.
