Marine Biology – Life Forms and Habitats in the World’s Oceans

 Marine biology is the study of the ocean’s plant and animal life. Marine life gives us food, medicine and other raw materials we need. It also maintains tourism andprovides us with an area of recreation. Organisms in the ocean produce oxygenand help regulate the earth’s climate. Coasts are partly created by marine life; some marine organisms even help to create new land. Marine biology ranges from very small organisms, like plankton, to huge […]

Cloning

Cloning occurs when you copy a living creature. Two clones have the same genes, small structures with information in them that tells them what the body of a living thing should look like and how it should behave. You get the genes from your parents. Many people think that cloning is only done by scientists in laboratories, but, in fact, cloning also occurs in […]

Insects have changed a lot and adapted to new climates in order to survive. Today, there are about one million different species of insects and scientists are discovering new groups daily. Insects have different sizes and body forms. Most of them are very small but […]

Bananas

Bananas belong to the most popular and most eaten fruits in the world. They were first grown in tropical India and Southeast Asia over 4000 years ago. Arabmerchants brought them to northern Africa and the Middle East. Portuguese navigators discovered bananas when they sailed down the Atlanticcoast of Africa.  From there they were brought to the Canary Islands, from where Spaniards took them to the New […]

The Food Chain

The food chain is the order in which animals and plants eat each other in order tosurvive. Every living creature needs to eat other creatures below it. Everyecosystem has a different food chain, depending on which animals and plants live there. The lowest part of the food chain are the plants. They are called producers because they produce their own food using […]

Vertical Farming – Agriculture of the Future

Vertical farming is the method of growing plants and crops over each other, mostly in buildings with many storeys. They often look like skyscrapers with glass around them, similar to a giant greenhouse. Such farming methods can already be seen in cities. For agriculture experts vertical farming will be in widespread use in the future because the world’s population is growing constantly and there is more need for farming land. The idea comes […]
