Scientist divide the world to different ecosystems.According to the United Nations Development Program, the world's ecosystems can be divided into five major categories: mountains; forests; arid and semi-arid; agricultural; and freshwater, marine and coastal ecosystems. All play an important role in the preservation of plant species, animal species and human life.Define ecosystem.
Every organism has a niche in life.• A niche is the role an organism has in an ecosystem.An organisms niche includes: the place it lives; the food it eats; the organisms that feed on it, interact with it; the amount of light, humidity and other physical conditions it needs to survive.
• Some organisms avoid unfavorable seasonal changes by “sleeping” through the bad periods of the year.• During this “sleep” the body functions of the animal slows down.• This enables animals to wait out the bad periods of the year in a sheltered hiding placeEverything is connected to everything else-Physical factors affects.
Note: One of the characteristics of life (living things) is adaptability.
Shows everything is connected to everything else.
Wildlife extinction is caused by the following:• Intentional Killing• Deforestation• Desertification• Wetlands destruction• Pollution• Changing communities – exotic species• Accidental killingPicture-Worcester’s buttonquail has been rediscovered, but on its way to the cooking pot. It is endemic to the island of Luzon in the Philippines, where hunters snared the bird, and the bird later turned up in a market where it was photographed.This species of buttonquail “was previously only known through drawings based on dead museum specimens.”
