Invasive species can outcompete native species for resources like food and habitat, disrupting the balance of the ecosystem. They may also introduce new diseases or predators that the native species aren't adapted to, leading to declines in native populations. Overall, invasive species can have negative impacts on the biodiversity and stability of ecosystems.

What is being done to stop or eliminate invasive species?
they kill most of them
What hunt and kill other organisms for food are called?
Organisms that hunt and kill other organisms for food are called predators.
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.
What organisms eat nereis?
Birds and other more predatory organisms can eat nereis, and flatworms can also kill them.
What harm do crayfish cause?
Native species of crayfish that are are a normal part of the ecosystem are not harmful. But there are several invasive species, like the rusty crayfish, that can kill off native crayfish and other crustacians. The rusty crayfish has a thicker shell and less "meat" and therefore are are not a good part of the food chain depriving the ecosystem of the nutrients from the crustacians it replaces. Invasive species also tend to destroy large amounts of water plants that further degrade the food chain. Also there is an infection that occasionally occurs in crayfish that can spread to other animals but this is usually a normal part of the life cycle and not neccasarily harmful.
Why ecologists are so worried about foreign organisms?
Foreign organisms refer to invasive species which inhabit a foreign environment. Usually invasive species out compete native species and kill them off by taking their resources (abiotic/biotic). And can be considered a "pest" because they are large in numbers and spreading/taking over native land and competing with native species. Therefore can really change an ecosystem when an invasive species comes in.
What is being done to stop or eliminate invasive species?
they kill most of them
What is being done to stop or eliminate the invasive species?
they kill most of them
What types of animals kill the kiwis species?
possums kill the chicks, eggs and the bird. weasels introduced by people to kill rabbits also kill them. hedgehogs introduced, kill the chicks and eggs. pigs can also kill the bird and eats everything. rats and other species of rodents cant kill the birds but can injure them and destroy the eggs and chicks
What happens when invasive species enter a habitat?
They eat all the food or the species that live there. And possible take over and kill things
Is it illegal to kill autumn olive?
Autumn olive trees are considered an invasive species. Pull them up.
Is it legal to kill a house sparrow?
Yes. These birds are not protected under the Migratory Bird Act. They are not native to the US and are an invasive species. You can kill them.
How has organisms impact the environment both direct impacts and indirect from eradication efforts?
Invasive species like kudzu, fire ants, and even pythons are major problems in many areas of the U.S. Herbicides and pesticides used on these organisms can pollute lakes and rivers. They can also harm or kill people and other native organisms. For example, a child could eat rat poison by accident.
What hunt and kill other organisms for food are called?
Organisms that hunt and kill other organisms for food are called predators.
What happens to invasive species?
Invasive species disrupt the natural order of an area. They do not have natural predators, hunt and kill animals that would feed the predators native to an area, and in some cases, can cause a complete collapse of the local ecosystem.
Why invasive species create such problem in the ecosystems they invade?
Invasive species can create problems in ecosystems because they outcompete native species for resources, disrupt the natural balance of the ecosystem, and lack predators to keep their populations in check. Their rapid reproduction and spread can also lead to loss of biodiversity and habitat degradation.
How could viruses be helpful?
Some viruses target harmful organisms. For example, bacteriophage viruses kill bacteria. Other viruses might kill mosquitoes or weevils or other harmful insects without hurting any other species.
