Natural selection
Natural selection
There are a great many environmental problems caused by carbon dioxide. These problems include the extinction of quite a few species of animals.
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
This is such a general question, there are too many answers to list here. Prokaryotic organisms are all bacterial species and since there is such a vast amount of bacterial species on the planet, there are just as many that can be pathogenic to humans and animals. Staph infections are caused by Stapphylococcusbacteria; food poisoning is caused by several species of bacteria, such as Clostridium perfringens, E. coli, or Bacillus cereu.
it is a diesease that kould kill the plantAnswerPlant diseases are usually caused by bacteria or fungi, but can be vectored, or carried, by a number of different means, including insects, wind, animals, humans, and farm machinery. Diseases vary widely from species to species in their mortality rate, symptoms, and effects.
Most animals are endangered because their habitats are being destroyed.People overkill the species without letting it repopulate.There are a lot of reasons of why animals are in danger...... because of Global Warming, Hunters, Pollution and a lot more.
Extinction is caused by a change in a species environment. The members of a species may not have adaptions that allow them to survive and reproduce in the changed environments. Extiction may also be caused by catastrophic upheavils that perish the entire living matter of that place and if an organism is localized to that region it may get ileminated.
The Columbian exchange introduced disease, famine and non native species of animals to the Atlantic world. The disease caused many epidemics among the Natives and the species of new animals wreaked havoc on plants. The Columbian exchange also changed the terrain

Nearly all endangered animals are endangered because of humans. We threaten them with habitat destruction, excessive hunting, or pollution. In addition, species such as rats that we've purposefully or accidentally put in environments where they didn't naturally live have caused extensive damage to their new ecosystems and threatened many species.
No, bottleneck events can be caused by various factors such as natural disasters, habitat destruction, and human intervention that drastically reduce a population to a small number. While death of most of a species' population can certainly lead to a bottleneck, it is not the only cause.
