Ecosystems
Plants and animals live together
• Plants need water and sunlight to survive.
• Some plants need a lot of
  water, they grow in wet places.
• Others, like palm trees,
  only need a little, they grow
  in dry places.
• It is the same for animals.
What is an ecosystem?
• An ecosystem is a place and the living
  things that live there.

                          ECOSYSTEM

     LIVING THINGS                    NON-LIVING THINGS
     Animals and plants                Soil, rocks, water
Big ecosystems
• Some ecosystems are big, like the
  savannah.
• Grasses, bushes and
  trees live on the
  savannah.
• There also many
  animals like zebras,
  gnu, hyenas or lions.
Small ecosystems
• Others ecosystems are small, like a pond.
• In a pond we can find many animals like
  frogs, dragonflies or snails.
• There are also water plants.
Food in an ecosystem
• Plants make their own food.
• Herbivorous animals eat leaves,plants,
  fruits.
• Carnivorous animals eat other animals.
• This is a food chain.
Other interactions
• Some plants live on other plants.
• Many birds build their nests in trees.
• Many animals like zebras or sardines, live
  in groups to defend themselves or to find
  food.
Forests are ecosystems
• The biggest plants are trees but there are
  also bushes and grasses.
• Insects are the biggest group of
  invertebrates. Spiders or worms are also
  invertebrates.
• There are also vertebrates
  like owls, rabbits or deers.
The sea is an ecosystem
• Seaweed is the most common plant in the
  sea.
• Many invertebrates, like
  jellyfish or
   mussels, live
   in the sea.
• Fish are the biggest group or vertebrates
  but there are also mammals, like dolphins
  or whales and reptiles like turtles.
• The sea is the biggest ecosystem in the
  Earth.
• There are three main zones in the sea:
          - The coast
          - The high sea
          - The deep sea
