BIOSPHERE


5º . Unit 6.          Biosphere.
http://study.com/academy/lesson/biosphere-definition-lesson-quiz.html
 The biosphere is defined as the sphere or area around the planet Earth where life exists. This zone of life is vast. Most lifeforms live on or near the surface of Earth. However, some live deep within the hydrosphere (oceans, lakes and streams), while others thrive in the depths of the lithosphere (solid portion of Earth). For this reason, mapping the exact borders of the biosphere is quite challenging.
The biosphere is all about life. Physical geographers use the term biosphere to describe our living world. All of the microbes, plants, and animals can be found somewhere in the biosphere. The biosphere extends to the upper areas of the atmosphere where birds and insects can be found. It also reaches to dark caves deep in the ground or to the bottom of the ocean at hydrothermal vents. The biosphere extends to any place that life of any kind might exist.

Every living plant and animal must have energy to survive. Plants rely on the soil, water, and the sun for energy. Animals rely on plants as well as other animals for energy. In an ecosystem, plants and animals all rely on each other to live. Scientists sometimes describe this dependence using a food chain or a food web. Food Chain A food chain describes how different organisms eat each other, starting out with a plant and ending with an animal. For example, you could write the food chain for a lion like this: grass ---> zebra ---> lion The lion eats the zebra, which eats the grass.

 The Food Chain
Every living thing needs energy in order to live. Everytime animals do something (run, jump) they use energy to do so.

Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and nutrients to get energy (in a process called photosynthesis). Energy is necessary for living beings to grow.
A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals.

Loss of Biodiversity


The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and transferring species from one area to another of the Planet. The threats to biodiversity can be summarized in the following main points:
  • Alteration and loss of the habitats
  • Introduction of exotic species and genetically modified organisms
  • Pollution
  • Climate change
  • Overexploitation of resources

6º. Unit 6.MATTER

MATTER IS ANYTHING THAT OCCUPIES SPACE



Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. If you are new to the idea of mass, it is the amount of stuff in an object. We talk about the difference between mass and weight in another section. Matter is sometimes related to light and electromagnetic radiation.

PHYSICAL CHANGES

 A physical change is a change in which no new substances are formed. Physical changes affect the form of a chemical substance, but not its chemical composition. Mixtures can be separated into their parts by physical methods, such as spinning in a centrifuge. but can not usually be used to separate compounds into chemical elements or simpler compounds.

Most physical changes are reversible. Examples: changes of shape, changes of states, passing electricity through a copper wire. Some physical changes are melting, freezing, boiling.





CHEMICAL CHANGES

We say there us a chemical change in a matter when the internal make-up (molecules) of the object changes. Unlike a physical change, chemical changes cannot be reversed. Changes that cannot be reversed are called Non-reversible Change.
There are usually one or more new substances formed or created from that change. You can tell there is chemical change when it produces a gas, light, smell, fire (heat) or color change. A chemical change may also be accompanied by the formation of a solid in the form of a precipitate, and in some cases, accompanied by a gain or loss of energy.
A good example is the change that occurs when you fry an egg:

SEPARATING MIXTURE
The different substances in mixtures are usually easily separated from one another. The method you use depends upon the type of mixture you have.

5º AND 6º. Unit 5.Ecosystems

5º and 6º. Unit 5.Ecosystems

 



Each individual plant and animal could not exist by itself on planet Earth. All living organisms need millions of other living organisms to survive. How these organisms interact with the sun, soil, water, air and each other in a specific area is called an ecosystem. An ecosystem describes a specific area where the organisms work together as a unit. It could be any size from a tiny pool of water to hundreds of square miles of desert. Each ecosystem is different and each has established a balance over time that is important to every form of life within the ecosystem.

What makes up an ecosystem?

   An ecosystem is made up of biotic and abiotic components which include plants, animals and the environment in which they are found. The living or biotic components are made up of producers, consumers and decomposers. Some of the non-living or abiotic components include sunlight, temperature, water and soil.

DIFFERENT ECOSYSTEM AND HABITATS



Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. You may also have more than one type of biome within a larger climate zone. Here is a short list of possible biomes.

- Tropical Rainforest (Think about Brazil)
- Tropical Savanna (Think about Africa)
- Desert (Think about the middle east)
- Mediterranean Woodland (Think about coniferous forests)
- Mid-latitude Grassland (Think about Oklahoma)
- Mid-latitude Deciduous Forest (Think about the east coast of North America)
- Tundra (Think about frozen plains of Alaska)
- Ice Caps (Think about the poles)
