aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population imbalance‚ predator versus prey imbalance and outright off balancing the entire ecosystem food web. The purpose of this paper is to discuss what an invasive species can do to an ecosystem and possible solutions to correcting the imbalance in the

Out of all the species that have ever existed since the beginning of time‚ 98% of them are extinct (Facts). There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry‚ 2). Scientists classify species into six different groups: plants‚ animals‚ insects‚ algae‚ fungi‚ and microorganisms (Today’s Situation). In the tropical rainforest alone‚ most species are disappearing at the rate of 1% a year (Sherry‚ 6). If the current trend continues‚ at least

LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the top of food chains‚ such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution‚ species with chronically small populations‚ migratory species‚ species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction

Endangered species are those considered to be at risk of extinction‚ meaning that there are so few left of their kind that they could disappear from the planet altogether. Endangered species are threatened by factors such as habitat loss‚ hunting‚ disease and climate change‚ and usually‚ endangered species‚ have a declining population or a very limited range. The current rate of extinction is thought to be far greater than the expected natural rate‚ with many species going extinct before they have
Premium Endangered species Extinction
ENDANGERED SPECIES Introduction An endangered species is a population of organisms which is at risk of becoming extinct because it is either few in numbers‚ or threatened by changing environmental or predation parameters. The International Union for Conservation of Nature (IUCN) has calculated the percentage of endangered species as 40 percent of all organisms based on the sample of species that have been evaluated through 2006.Many nations have laws offering protection to

Write an essay title human beings are the most gifted species in the world. Humans are categorised as group of mammals‚ humans occupied the highest population in the globe‚ which is approximately 7 billion. Modern humans like us are also known as homosapien‚ humans are said to be the most gifted species in the world this is because humans are the most intelligent beings on the earth‚ most evolved species‚ the most advance life forms on the earth and classified at the highest level in the food

Human influence on species evolution Greed is a capital sin‚ but many businessmen do not care about that in order to raise their profit. Thus people who earn money by hunting animals always aim at the biggest and most superb ones. By looking at the nature‚ one can recognize that the predators usually take either the very young or the weak animals. First it sounds like an insignificant difference‚ but the effect of it is disastrous. Nearly every creature adapts to changing circumstances and

area‚ the larger species it can support. Aim: To see how the size of an area affects the relationship between species diversity. Diversity is a range of different elements. Habitat size determines diversity relationship(Edition of Nature‚ March 28 2002). In the research of specie diversity ‚ it was found out that more productivity was done when two different types of species were in one area. It was also said that diversity goes down but as it goes down the productivity of the species increase. Variables:

off the endangered species list. Many people think that they cannot do anything to help these poor animals‚ but they are wrong. There are many ways in which people can help to keep these animals from becoming endangered or help save them. There are many endangered animals and they come in all shapes and sizes. Ninety-nine percent of the earth ’s creatures have become extinct. Just in the United States more than a dozen insects‚ mostly butterflies are on the endangered species list‚ along with over
