The Living World

          Nature surrounds us in the form of the living world, a world made up of living things. It is an amazing World.
         Life on Earth Began about 2.5 billion years ago.

Plants:

From the tiniest flower to the largest tree,  there are an immense variety of plants.  Scientists believe there are about 400,000 species, but it may be many more.





Flowers:

Many plants produce flowers.  These are pollinated by animals, wind, and by the plant itself. Pollination results in the seeds needed to grow new plants.





 
Fungi:

 They may look like plants, but fungi are neither animals nor plants, but they are living things.





 
Animals:

The animal kingdom consists of vertebrates ( animals with a backbone)  and invertebrates (the creepy - crawlies)




Animals with Backbones:
Vertebrates, or animals with backbones, are dividede into five categories. Mammals breathe air. Most live on land but some are aquatic.

Birds have feathered wings. Most can fly , but not all


Reptiles are cold blooded and rely on their environment for body heat.


Amphibians are able to live on land or in water.  They are cold-blooded.
Fish live in fresh water or sea water - or some can move between the two.
