Перевод на русский:
A) Energy moves along the food chain from one life form to another. Some animals eat plants to get energy. Other animals then eat these animals to obtain the energy they need. Plants, on the other hand, produce their own food using energy from the sun. They do this through a process called 'photosynthesis'.
B) Photosynthesis uses energy from the sun to change carbon dioxide (C02) and water (H20) into carbohydrates. Carbohydrates are chemicals that contain hydrogen, carbon and oxygen and they are the plant's food. To start the process, the plant absorbs carbon dioxide through tiny holes in its leaves and sucks up water from the soil through ^ts roots. A green substance in the plant's leaves called (chlorophyll absorbs energy from the sun. The plant now has all it needs for photosynthesis to begin.
C) There are two stages to the photosynthesis process. In the first stage, called the light reaction, light energy from the sun is converted into chemical energy. This energy is stored in a chemical called ATP (adenosine triphosphate). The second stage of the process is the dark reaction. In this reaction, the plant converts the carbon dioxide and water into carbohydrates. Carbohydrates provide the plant with the energy it needs in order to grow.
D) The chemical reaction involved in photosynthesis can be summarised by this equation:
E) The equation shows how important photosynthesis is for life. As well as providing food for the plant from the sun's energy, the equation shows that the reaction also produces ! the oxygen that animals need to breathe. Without [photosynthesis, our planet could not support life as we 'know it.

The Great Barrier Reef.
Welcome to Australia's Great Barrier Reef! The 2,000-kilometre long reef is the largest coral reef system in the world - it is so big that it can be seen from space!
Like many other coral reefs in the world, the Great Barrier Reef is in danger. The numbers of fish and other creatures that live here have fallen drastically in recent years because of pollution. We need your help to protect this unique ecosystem.
Help us protect the wate.
The sea around the reefs has been seriously harmed over the years, but you can help reverse this. Don't throw rubbish into the sea as it may contain chemicals that will pollute the water. Rubbish might also float to the surface, which isn't pretty for anyone to look at! Help us to keep the water crystal clear so that it can be enjoyed by everyone.
Help us protect the coral.
Remember that the reef is very much a living organism! It has been formed over thousands of years by the action of tiny creatures called coral polyps. We have to protect these creatures if the reef is to survive. If you are camping on a beach, please be careful what you do with any waste water. Washing-up liquid and bleach can be fatal to coral. If anyone offers to sell you a piece of coral, don't buy it. If you see coral for sale in a shop, tell the authorities immediately.
Help us protect the wildlife.
The reef is home to 1,500 species of tropical fish, over 200 types of bird and 20 species of reptile, including the endangered Green Sea Turtle.
It is also a breeding ground for humpback whales from the Antarctic. Remember - all these creatures depend on the reef for their survival. Please never fish for anything! Many species of fish are in danger of extinction and therefore protected by law. The same goes for shellfish and other creatures. They may look beautiful, but remember the reef is their home. How would you feel if someone picked you up and took you far away from your home?
Please help us to conserve Australia's natural treasure so that it can be enjoyed for generations to come!
