What is a Producer ?
           Producer(explained)
            Are green plants.

           Producers are
            responsible for
            producing all of the
            energy in the
            ecosystem.
Energy Producers…How?
            Green planets are able to
             take radiant energy from
             the Sun transform it to a
             form that can be used by
             plants and animals.
            Consumers(animals) can
             not do this. Animals have
             to go out and actively find
             food. Plants make their
             food.
   Energy Producers… How?
 Plants make their food by a process called
  photosynthesis.
 Photosynthesis is the most important
  chemical reaction that takes place on the
  planet. Without it other life would be
  impossible.
Photosynthesis
        Photosynthesis(explained)
         green plants take water
         from the ground, carbon
         dioxide from the air and
         radiant energy from the
         Sun and produce
         carbohydrates(food for
         plants and animals) and
         oxygen.
                Producers
 Every ecosystem has
  to have producers.
Producers
      Producers(green
       plants)produce food
       for consumers in all
       their parts.
      seeds, flowers, leaves,
       wood, roots and fruits
       are eaten by
       consumers
Producers
      Besides food and
       oxygen producers
       provide habitats and
       places to hide for
       animals.
Producers in a Pond Ecosystem
 The main producer in the
  pond ecosystem is
  phytoplankton or algae.
 Phytoplankton are tiny
  free floating green plants
  in the water column. Give
  the pond its greenish
  color.
 Major source of food and
  oxygen in the pond
  ecosystem.
Producers in the Pond
     Ecosystem
            Also provide a hiding
             place/cover for many
             small animals in the
             pond
            Other producers:
             Water Plants: pickerel
             weed and cattails
            Terrestrial Plants:
             willows, grasses
