of study‚ many people forget about the environment. Some will just throw their trash all over the place with no concern for the possible consequences. Of course‚ there are many consequences‚ but only one comes to my mind. That is the demolition of species’ homes or habitat destruction. Habitat destruction or habitat loss is the altering or elimination of the conditions that plants and animals need to survive. "The primary threat to the world’s biodiversity is habitat destruction" (Okey p.1). Prairies

Questions: What are the current condition of endangered species in Canada? What are the major factors that cause species endangerment? What are the actions the Canadian government had been taken to save them? Introduction Canada is one of the biggest places on earth with extensive wilderness protected areas that are providing home for more than 70‚000 wildlife species. Among the rest‚ 488 species are categorized by COSEWIC (Committee on the Status of Endangered Wildlife in Canada) as extinct

Many species today are impacted by threats from changing environments. These threats can pose a great amount of harm to a specific species‚ which in turn‚ can ultimately cause it to be endangered. A species is considered endangered when a threat is relatively high and a population is rapidly declining in size. One of the most effective ways to identify an endangered species is through acknowledging habitat loss‚ introduced species‚ pollution‚ and overconsumption. This paper will investigate two endangered

there just isn’t enough room for all of the different species. Scientists say that “if you had a huge balance and put zebra mussels on one side‚ they would outweigh all the other consumers in the ecosystem combined.” (River ecology pg.6). With the zebra mussels taking up over half of the population of the river‚ there isn’t much room left for other organisms. The lack of diversity in the river is a huge problem to the food chain‚ because once a species no longer exists‚ it is hard for larger animals to

Castor canadensis‚ otherwise known as the North American Beaver‚ is a keystone species on the verge of extinction. It lives in the northern regions of North America‚ specifically in Canada and the United States. Its status on the IUCN red list is endangered. This species is very beneficial‚ but is racing extinction due to people not seeing the importance it does to both humans and the ecosystem alike. The benefits of these beavers are that they prevent water floods and regulate water flow which

Our ecosystem relies on the basis of food chains. Food webs work through a series of food chains that link together. Invasive species are a part of our food web. Invasive species pose a great threat to the habitat of the existing native organisms. They can cause major disruptions to the existing habitats and so it is important to be able to stop their damage. Invasive species can be found in many different habitats including land and water. If the population of a given habitat increases‚ then there

An invasive species such as the zebra mussel‚ invaded the Great Lakes of America in 1988. They were brought in by seagoing vessels that emptied their ballast water as they got in the port‚ the zebra mussels had hitched a ride in the water taken in in the ballast before the ship left port in the Caspian and Black seas. By 2010 these muscles and colonized the waters in over 30 US states spreading like wildfire. Invasive species have a huge impact on their nonnative environment‚ the zebra mussel clogs

Ivan Chavez B1 Invasive Species: The Mexican Fruit fly An invasive species is a species that does not naturally take place in a particular area and with its arrival brings economic‚ environmental or human harm (1). Recently there has been a bigger emphasis on invasive species (1). They are threatening our agriculture and forests and causing major impacts to our cities (1). The characteristics that make the species thrive in their environment vary with each. Their characteristics

Types of species 1. Endemic species Endemism is the ecological state of a species being unique to a defined geographic location‚ such as an island‚ nation‚ country or other defined zone‚ or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. they are only found in certain locations‚ they require special conservation efforts Animal examples: Lemurs of Madagascar‚ tortoises of the Galapagos‚ polar bears‚ koalas‚ kangaroos.
