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.

Do new species effect the food chain?
yes they do im not sure how but i know they do. :)
How can a new species with no predator affect other populations of species?
Their population could grow much faster, and they could compete with other species for food.
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.
How does variability within a species affect its survival?
The introduction of a new predator, the spread of a new disease, the introduction of a toxic substance, or the elimination of a food source are all examples of environmental changes that could affect the survival of a species.
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.
What affect tectonics have on evolution of new species?
what affect tectonics have on evolution of new spiecies
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.
How does plate tectonics affect development of new species?
The movement of plate tectonics greatly affects the development of new species. With movement, species can become isolated to specific areas and must adapt to the new/changed environment. Also, depending upon the event (volcano/earthquake) the climate will be affected which requires further adaptation of species.
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.
Explain how Darwins finches illustrate the principle of character displacement?
This new species needed the same resources so they competed for food and they started to evolve and soon had new beaks. Now that they evolved, they could eat different food and actually survived!
