Classifications of extinct animals
Extinct
a member of the species has not been spotted for 50 years Extinct in the wild The species does not exist in its natural habitat but are heled captivity Locally Extinct The species is not living in some of their natural habitat but are living in others Ecologically Extinct Has too few numbers to perform its normal role in the ecosystem |
Biodiversity
What is Biodiversity?
Biodiversity is the variety of life in a given area. This is measured by the number of species present in the given area more meaning a better biodiversity and less being worse. The most bio diverse climate are warmer climates, coral reefs, tropical rain forests and large tropical lakes.
Island biodiversity
A larger island has more biodiversity if all the abiotic (non-living physical and chemical attributes of a system) factors are the same simply because there is more space for different environments. The exception is if the smaller island has a warmer climate it probably has a greater biodiversity.
Importance of Biodiversity
Biodiversity does many things to nature it adds beauty. Violating a part of the food chain can have a devastating effect on a community. Biodiversity helps stabilise an ecosystem. Biodiversity is also very important to humans the plants convert CO2 to oxygen and without that we would die. It gives us an increased crop production which gives us a larger variety in our diet. It also gives us important medicine such as penicillin.
Threats to Biodiversity
The major threat to biodiversity is the changing and loss of habitats that is threatening many organisms. A species losing its habitat means it loses an essential part of its life an example is draining of a swamp for housing developments. Another treat to biodiversity is habitat fragmentation or the separation of a natural land areas from other ones. Example building cities and roads through natural areas. Habitat Degradation is a damage to habitat by pollution. The greatest source of air pollution is burning fossil fuels and this could cause breathing, eyes and nose irritations. Water pollution damages aquatic habitats especially algal blooms, because they use so much oxygen it suck it out of the water which causes the fish to die. The third pollution land pollution, landfills destroys the wildlife systems and cause bad pollution around the surrounding area. The last threat is introduction of exotic species, this is introducing a species not common in the specific area. For example the cane toad introduced to Queensland and since then have come uncontrollable, this is because of the lack of predators.

1) a) adds beauty to nature and makes every place unique
b) brings stability to ecosystems because every species performs a certain function within the ecosystem.
c) Life depends on life and disrupting the food chain could have a catastrophic effect on the ecosystem in the area
2) Threatened is when a number of a species is declining rapidly. Endangered means that they have a chance of going extinct in the near future.
3) When a species is extinct it means there are none of that species left in the world. Threatened and endangered means that there is still some of the species remaining but very few and have a high chance of going extinct in the near future.
4) Introduce laws that will protect the endangered wildlife and environment. This will stop people from hunting and killing endangered animals. It also stops and companies from ruining the habitat that many animals live in. Set up a nature preserve and habitat corridors. By doing this it will help protect a whole community of organises and the ecosystem. Setting up a habitat corridor it will let the animals migrate from one land area to another. A reintroduction program is another good idea to protect biodiversity. By taking endangered animals out of the wild reproducing them and putting them back this significantly helps to boost their population. Taking the animals out of an area that is in threat of being abolished and putting them in an area with a similar ecosystem will also help save biodiversity.
5), 6) California Condor was the most endangered species of bird in the United States and all birds were removed from the wild in 1988. After a captive breeding program put in place to boost the numbers of the species the first young ones have been introduced back into the wild. The Przewalski’s Horse disappeared from the wild after major loss of habitat and excessive hunting. Other endangered animals included the American alligator, Homerus Swallowtail Butterfly (which became endangered due to over collecting), Scimitar-Horned Oryx and The Tibetan Yak.
7) The California Condor became extinct in 1987 with all wild remaining condor's being captured and put into captivity. They were reintroduced into the wild and a count in 2014 had 435 known condors, 237 in the wild and 198 in captivity. Przewalski’s Horse is still living and has been an endangered classification on it. The American Alligator is still living in quite large numbers and is under the less concern classification. The Homerus Swallowtail Butterfly is still on the endangered list due to loss of habitat and over hunting. The Horned Oryx is
