What is being done to stop or eliminate invasive species?
they kill most of them
How do invasive species disrupt ecosystems?
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.
How could the introduction of an invasive species to an ecosystem cause natural selection to take place in a native species?
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.
How oceans and seas are being polluted?
Where the sea is polluted by sewage, trash, oil spills and waste.
How an organism survives in an ecosystem?
Organisms survive in an ecosystem by being in a food chain or adapting to the resident food web. For an organism to survive in an ecosystem in needs to find a way to belong. Sometimes when an new organism is introduced to an ecosystem they adapt too well and they are classified as an invasive species. The organism will either have to adapt to the ecosystem or die out.

Why are invasive species dangerous?
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.
How are zebra mussels being controled?
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.
What tree is described as being an invasive species in Oklahoma grasslands because the praires do not burn as often as they did in the past?
Eastern Red Cedar. Had to find the answer for a Bio class
Sometimes animals that are introduced into an area that they have never lived in before out- compete and endanger resident species?
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.
National ballast water laws in the US would hurt economic globalization?
"As the United States becomes more aware of its economic dependence on a global market and the impact that invasive species have in the movement of people, products, and supplies, so too will the role of the nation's socio-economic well-being become a part of the equation in managing invasive species." This is from the invasivespecies@doi.gov
Why is bamboo being cut down?
Some areas, bamboo is an invasive species. When it takes root in an area where there are no natural controls, it sort of runs wild, and will crowd out all other plants.
What are the impacts of invasive species on human society?
The best example I can think of is Florida. There are several invasive species there that are causing a lot of problems. The most worrisome being a few varieties of python. Burmese pythons have grown to a large population, and African Rock Pythons are starting to grow in number. They are reducing the numbers of most of the native species in the everglades, and human deaths due to wild pythons in Florida are becoming more and more common.
