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, and
2) 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.

What are the negative impacts of an alien species on ecosystems?
The presence of an alien species may lead to inter-specific competition. An alien species may reproduce quickly due to a lack of predators of the species's ability to utilize resources that native species cannot. The alien species may even introduce diseases. Predation by the alien species can lead to a loss of biodiversity and some native endangered species may be driven to extinction.
Is snake a primary consumer?
Not in all ecosystems. There are some species of snakes that eat birds.
Why is biodiversity important and how can we preserve it?
Biodiversity is the variety of life on Earth. Biodiversity include the genetic variety among individuals in a species, the number of species in an ecosystem and the variety of ecosystems in the biosphere. The main factors causing the threat to biodiversity are pollution, habitat destruction, introduced species and overexploitation.
What are some things about ocean ecosystems?
they are ecosystems!
Which animals and plants live in the grassland ecosystems?
Some of the plants in a stream ecosystem are water lillies, cattails, moss, and hydrillas. And some of animals would be freshwater turtles, frogs, salamanders, and many different species of fish, all of these live in stream ecosystems.

Are some alien races headless?
No alien species have yet been found or identified as such, therefore no definite answer can be given. If we want to speculate, in an infinite universe there will be a chance that headless species will occur, as headless species occur on Earth. They might even be intelligent!

Are some alien races noseless?
Noseless species of aliens may indeed exist but until alien races are discovered one cannot know for sure.
