There are a lot of reasons.
One is a big cloud (like one resulting from massive volcanic activity or the impact of a large asteroid) can block the Sun and plants would not survive, so then many herbivores die followed by most carnivores.
When an environment changes the organisms living in it may not have the time to evolve to adapt, and so they die.
A change in climate can lead to extinction because it can destroy organisms' habitats. For example, woolly mammoths had thick fur that was perfect for keeping themselves warm in the cold area. When global warming caused the climate to become warmer, their traits for cold weather were no longer helpful and eventually became extinct.

∙ 13y agoGlobal warming is warming our planet and melting our polar icecaps. Eventually these polar icecaps will completely melt, this will make certain animals extinct such as the penguin and the polar bear. the melting will raise the sea levels and cause all other species on land to die out.

If for any sad reason a Species were to be Eliminated the easiest way to accomplish this would be to Eliminate It's Habitat. Expect repeated ?accelerated? Examples of Extinctions.

∙ 10y agoEvery species has a particular environmental adaptation. An animal might be adapted to cold weather, and if the weather gets warmer, the animal will no longer be well adapted to its environment (or will have to move to a different, colder environment if one can be found). If a fish is adapted to fresh water, but the water becomes salty, then the fish is no longer adapted to its environment. A bird species might be adapted to nest in a particular kind of tree, and if that tree is cut down and ceases to be available, the bird will have nowhere to nest.

What does the greenhouse effect lead to?
The natural greenhouse effect leads to keeping the earth warm enough for life.The enhanced greenhouse effect (caused by burning fossil fuels and deforestation) leads to global warming and climate change.
Does climate change leads to an increase in rainfall and more storm events?
Depends on the region, typically warmer oceans results in more evaporation leading to higher levels of precipitation (rain,snow,storms) particularly in coastal regions.
How do humans affect the tundra biome?
Three (of many) anthropogenic causes of Tundra decline are Climate Change, Overfishing/Hunting, and Development. I'm sure you are aware of climate change and the effects on temperature. Leads to invasive species and the spread of new habitat while reducing actual tundra habitat. Overfishing and hunting obviously wreak havoc on the ecosystem. Development is a more complicated one. If you run an oil pipeline down the middle of Alaska, and build a bunch of access roads all over the place, then you fracture the natural landscape. This fracturing reduces the habitat into several smaller ones, and species are often cut off from each other. This inhibits their breeding ability and what not. Add to the last one that plant regeneration in tundra is extremely slow. If you drive a car over a part of the tundra, the tracks can remain there for months, even years! This probably has the most immediate effect on the biome itself (and climate change/greenhouse gasses, etc), but they are all related.
What could global warming lead to?
Global warming is leading to climate change.Positives:Warming of northern climates like Canada and Northern Europe may lead to increased agriculture productionDecreases in Famine due to more tillable land and increased productionFewer deaths from cold weatherLess energy used for heatingPrevention of the next ice ageOpening of the Northwest passage for shippingNegatives:Spread of tropical diseases and pests, like malaria and killer beesCrop lands becoming desertPacific Island countries under waterRising sea levelsFlorida, Bangladesh and other low lying areas under waterFamine increasing across poorer countries, especially in AfricaGlaciers melting and the rivers they feed drying upMillions of climate refugees at international borders.Extinction of many animal species as their habitats change or disappear.More deaths from heat exhaustion and heat strokeMore energy used for cooling and air conditioning
What are the two types of greenhouse effect?
The natural greenhouse effect keeps the earth warm enough for life.The enhanced (or accelerated) greenhouse effect (caused by burning fossil fuels and deforestation) leads to global warming and climate change.(There is also the very dangerous runaway greenhouse effect that happened on Venus.)
How many endangered species were there in 2005?
Hundreds of endanger species could be lost by 2025 due to habitat loss. As humans expand and change the landscape, it directly leads to the extinction of many species.
How could climate change or new species affect an ecosystem's stability?
These are two different questions and need two different answers. Climate change could mean warmer temperatures, causing heat stress in the flora or fauna of the ecosytem. It could mean more prolonged droughts, so that some species can not longer survive in the environment. It could alternatively mean more frequent floods, causing destruction of specimens and destabilising the ecosystem. Greater storm activity associated with climate change can also have a deleterious effect on some species, destabilising the ecosystem. Climate change can even favour one species over another and, if they are competitors or prey, create an imbalance that leads to extinction. Introducing just one new usually has a lesser impact on an ecosystem, although any unforseen effect could result in localised disaster and widespread species extinction. Any loss of plant species could potentially lead to serious erosion and loss of topsoil and even, in the extreme, desertification.
Over time change within species leads to the replacement of old species by new species as less successful species become?
extinct.
What was the impact of deforestation as reflected in environment in the 18th 20th century?
One of the negative impacts of deforestation is the destruction of habitats for various species. It also leads to climate change and the increase of greenhouse gases.
The model of evolution in which gradual change leads to species formation over time is called?
gradualism
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
How has Germany addressed climate change at an international level?
Germany leads Europe in the amount of solar energy from photovoltaic panels.

What caused the Devonian mass extinction?
No one knows for sure. Some people believe that an asteroid earlier in time hit Earth and caused massive climate change that killed off reptiles, but spared dinosaurs. Others believe that it was simply climate change.
What would happen if the competition for food leads to extinction?
This frequently happens. Loss of habitat leads to loss of food sources and shelter. Often, when new non-native species are introduced, it is usually the introduced species that thrives and the native species that becomes extinct. Ultimately, what happens is that yet another species gets marked down as extinct, but nothing is done to address the problem. .. On the other hand, would a species "get marked down" if no observation of it is made? would another species benefit from the extintion? would a species that benefits from the the more plentiful food source consider it "a problem"? would another species suffer a change of diet? is there a species that relied on the feces of the extinct species, or the breath of the species, or some intestinal function, or needed the food source to be kept in check that the extinct species was competing for? would another species be able to use the winning species as a food source, or symbiont, or ...
Can sugar be separated from salt using a magnet?
no it really cannot. This is becauseDeforestation leads to the extinction
How do glaciers change the climate of a location?
Glaciers are large masses of COLD. When they get smaller, the micro-climate nearby warms up, further speeding up more melting, which leads to slightly more warming, and so on.
