For one thing it may eat the other species. For example the introduction of the house cat in to the wild in western Australia led to the demise of many small land welling creatures, to the point where cats are now seen out at sea hunting for fish. It can also starve the existing species in an area out by eating that which the established species needs to survive. The cane toad was introduced into Australia and is now causing a problem with animals that eat or bite ir as they are poisonous.
cause of deforestation
The most extreme that we are aware of was the Permian Extinction about 252 million years ago, in which 95% of all life was killed. The cause is still unknown, although it is possible that this was an impact event.
a good introduction for an essay is well... you have to think of it yourself no one really can write an essay for you cause basically you r cheating just come up with one that falls into what your ideas are and the main subject the topic.
The disadvantages are that the change in water flow will effect the fish and making space to put the hydro facility can cause the deaths of plants and animals aswell as destruction of habitat. Hydroelectiric facilities do not produce much electricity compared to other renewable sources.
The cause of the cause is also the cause of the thing caused.
because of the habitat!
Bengal Tigers are not in fact extinct, though three sub species are. The cause of the extinction of these three sub species are over hunting, and habitat destruction. The same goes for the Endangering of the other six sub species still alive today. http://en.wikipedia.org/wiki/Tigers
Alterations of a habitat may lead to drastic changes in a ecosystem and may even lead to the extinction of a species.
Because of loss of habitat
Yes.
Poaching is by far the primary concern in the conservation of all species of rhinoceros. Secondarily, habitat loss definitely doesn't help.
Of global warming Mostly by lost of habitat.
Loss of habitat no human nature
Provide them with a habitat in which they can live. The primary cause of extinction is destruction of habitat.
Which of these is not a reason that species become extinct
It is mostly due to habitat loss and fragmentation and a decline in quality of remaining habitat. Habitat fragmentation causes populations to become divided, creating smaller populations which are less connected and therefore at greater risk from disease, fire, predation, etc. If a species is already endangered, urbanisation puts more pressure on remaining populations and may encroach on crucial habitat. Urbanisation is unlikely to be the sole cause of extinction but it can contribute heavily to species becoming threatened or endangered.
yes it was and i hope it helps ;o
