What new species affect the food chain?
Any new species being introduced into an area will affect the food chain in one way or another. More often than not, especially if the introduction was deliberate, while the new species may be of great help in keeping a pest species under control, it will hurt other species within the food chain because of competition for food, predation that was not present previously, or any number of other factors.
What is the food chain of the dottrel?
The dotterel is a sea, shore, and wading birds, the New Zealand species is endangered. Their food chain would be small fish, small crabs, and other small shore creatures.
Introduced species often take over an ecosystem because they usually what?
Introducing new species threatens biodiversity in several ways. The new species may upset the food chain in an area. If a species grows faster than native species, they may eat all of the food, leaving little for the natural fauna. The new species may also, conversely, be great food for an existing species which would give one species a great growth advantage over others.
How does the success of an invasive species depend on its placement in its new food web?
It needs to eat food, and if their food is vanished then they too can die. I something in their food web goes extinct, it will also effect them.

What would happen to a food chain if a new organism joined the ecosystem?
The food chain would expand, and the new organism would have new predators.
What causes ecosystems to change over time?
Many things can cause change in ecosystem. These include habitat destruction for human builds, Introducing new species to a ecosystem that are not part of the food chain, Poaching, and even most pestacides can cause severe change to an ecosystem. Food chain disturbance example: Lionfish. They were somehow introduced by being let out of an aquarioum. These exotic fish are disturbing the food chain and causing many different other species of fish like grouper to have no food to eat.
Sometimes animals that are introduced into an area that they never lived in before out compete and endanger resident species why do you think this happens?
The original species is not used to the new predators and have not adapted to having them "in the area" so they will get out-competed leaving them with little resources leading to an endangered species while the new species dominates and goes to the top of the food chain.
Why are some alien species a threat to ecosystems?
The two most common reasons non-indiginous species are threats to ecosystems are these:1) The new species takes resources, thus depriving indiginous species of those resources, and2) The new species upsets the predator / prey balance in the existing ecosystem.For example, if you were to introduce snakes in an area with no snakes, that could have the effect of depleting the population of rodents in that area, due to snakes' appetite for rodents. Because this is a new demand for rodents, you would be depriving birds of prey (for example) of the rodent food source, and you would be population INCREASE of those foodstuffs on which rodents feed. It is quite easy to see how this new species (snakes) could lead to further upsets in the ecosystem, both up and down the food-chain.
How do endangered species adapt to its new environment?
When introduced into a new enviroment, an animal has no natural predators. Since no animals are hunting it, the new species will survive easier than in its old habitat. However, this throws the food chain off balance and over time, the species will over-produce.
What is an effect of adaptive radiation?
speciation
Why and how would a new species have effect on the ecosystems?
It would have effect on ecosystems because it could have dieses that other animals have never encountered before. It would have effect on it because it its new.
