The Role of Producers in an Ecosystem

  • Science 8

  • 9/5/07


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
