Not in all ecosystems. There are some species of snakes that eat birds.
The environmental threats to the use of hydro electricity may include the loss of habitat for native species, during the construction of new dams -- the survival of some of the displaced species may be threatened.
Hunters will sometimes kill them for sport, but the golden eagle is not an endangered species.
they are ecosystems!
Ecosystems can be as small as a puddle, as big as a building. Some include plants and animals, rocks and soil, etcHere is the real answer hold it in till you can go to the RESTROOM!!
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.
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.
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.
kiara is very sexy and the ecosystems in haiti is water ecosystems andmany others...
Well, biodiversity means, variety of all living things, so humans are threats to almost every animal..... but animals like lions and tigers are threats to other animals, just as We are threats to them, if you don't understand this, I advise you to look up food chains, and you will find it clearer.
there is no threats in the rainforest
