Food Web: Zoom Rainforest - 0 views

  • A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A network of many food chains is called a food web. The food chain starts with plants or other autotrophs (organisms that make their own food from light and/or chemical energy) - these organisms are called primary producers. The primary producers are eaten by herbivores (plant-eaters) called primary consumers. The herbivores are eaten by carnivores (meat-eaters) and omnivores (animals that eat both animals and plants) - these organisms are called secondary consumers. Secondary consumers may be eaten by other carnivores called tertiary consumers. When any organism dies, it is eaten by tiny microbes (detrivores) and the exchange of energy continues.

      rainforests make air and oxygen by absorbing Co2
  •  
    they absorb CO2 that are out form humans and animals. Then they changes it to air and oxygen.

Rain Forest Destruction, Shameful Result of Our Spiritual Crisis - 0 views

  • Indeed, tropical forest is a victim of a spiritual crisis in humanity. The destruction of tropical forest reflects an all too-widespread willingness to submit to an economic determinism every bit as rigid as that of Marx. Egbert Giles Leigh Jr. (1) Rain Forest Destruction, Madagascar Photo: Jonathan TalbotWorld Resources Institute, 2003 We learn from Columbia Encyclopedia that in very early times forests covered virtually the whole land surface of the Earth, apart from the areas of perpetual snow (such as the north pole). (2) And as recently as 19 th century, tropical rain forests in their own right covered around 20% of all the dry land area of the Earth, but this figure was only 7% by the end of the 20 th century. (3) Probably the main fundamental factor that has been invariably pushing rain forest destruction more and more over the decades and indeed centuries, is the demand for the rain forest as a enormous economic and social resource. First of all, tropical rain forests are “treasure troves of nature” – they contain endless supplies of resources widely used in human societies, such as food, timber, raw materials etc. Second, rain forests cover huge swathes of land. And the land has always been a limited resource required for accommodation of ever growing human populations.

  •  Amazingly, only cover 6 - 7% of the total land surface on Earth is covered by rainforest.  On average, there are between 20 to 80 different species of trees per acre.  There is also a wide variety of animal life found in the rainforest.

Lemurs of Madagascar - 0 views

  • Madagascar is world-famous for its lemurs—primates that look something like a cat crossed with a squirrel and a dog. These animals are unique to the island and display a range of interesting behaviors from singing like a whale (the indri) to sashaying across the sand like a ballet dancer (the sifaka). Below you will learn more about these fascinating creature

    The Food Chain RealAudio Click here to be joined by your audio host! What is the difference between the 'Food Chain' and 'Food Web?' A popular misnomer, the 'food chain' is not actually a linear chain but a complex web. Energy is passed from one organism to another in a complex network like a spider's web. The food chain consists of four main parts: * The Sun, which provides the energy for everything on the planet. * Producers: these include all green plants. These are also known as autotrophs, since they make their own food. Producers are able to harness the energy of the sun to make food. Ultimately, every (aerobic) organism is dependent on plants for oxygen (which is the waste product from photosynthesis) and food (which is produced in the form of glucose through photosynthesis). They make up the bulk of the food chain or web. * Consumers: In short, consumers are every organism that eats something else. They include herbivores (animals that eat plants), carnivores (animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses). Primary consumers are the herbivores, and are the second largest biomass in an ecosystem. The animals that eat the herbivores (carnivores) make up the third largest biomass, and are also known as secondary consumers. This continues with tertiary consumers, etc. * Decomposers: These are mainly bacteria and fungi that convert dead matter into gases such as carbon and nitrogen to be released back into the air, soil, or water. Fungi, and other organisms that break down dead organic matter are known as saprophytes. Even though most of us hate those mushrooms or molds, they actually play a very important role. Without decomposers, the earth would be covered in trash. Decomposers are necessary since they recycle the nutrients to be used again by producers. This table shows the relational biomass of each of the major g

      this is going to be very useful to those who are doing the rainforest people.
    • Zoe P
       
      That is a good description
  • They wear little clothing because it is always warm in the rainforest. They make their clothing from leaves and things they find in the rainforest, too. Their way of life is in danger because of the destruction of the rainforest that they live in. The government has tried to teach them how to farm, but the Mbuti don't want to change the way they live.

  • Tropical rainforests are warm, wet forests with many tall trees. In most tropical rainforests, it rains every day. Tropical rainforests grow in a narrow zone near the equator. They are found in Africa, Asia, Australia, and South and Central America. The largest rainforest in the world is the Amazon rainforest in South America. Tropical rainforests are home to a huge number of different plants and animals. All tropical rainforests are endangered.
