The Food Web PowerPoint

This presentation is a PowerPoint on the Food Web I completed in Geology. This goes into great detail about consumers, producers, and decomposers.

The Food Web PowerPoint

  1. 1. The Food Web Averie Daniels and Madison Strama
  2. 2. Food Web  A food web consists of many food chains.  A food web shows many different paths that connect plants and animals. A food web is many food chains connected.  A food chain only follows one path of an animal finding food.  There are two types of food chains:  Aquatic and terrestrial  Aquatic = water  Terrestrial = land
  3. 3. What is in a Food Chain?  Producers  Consumers  Decomposers
  4. 4. Producers and Where are they located on the food chain?  Producers make their own food from abiotic compounds.  Green plants use energy from the sun to make their own food.  They are located on the bottom of the food chain.  It takes a lot of producers at the bottom of the pyramid to support the organisms above them.  Example: Green plants and algae
  5. 5. Consumers  Consumers are organisms that feed on other organisms or organic matter because they cannot produce their own food.  Depend upon food provided directly or indirectly by producers.  There are 3 levels of consumers  Primary Consumers  Secondary Consumers  Tertiary Consumers
  6. 6. Trophic Level  Organisms place in a food chain  Trophic relationships are expressed as a pyramid  First Trophic Level=Primary Producer  Second Trophic Level=Primary Consumer  Third Trophic Level=Secondary Consumer  Fourth Trophic Level=Tertiary Consumer
  7. 7. Food Pyramid Primary Producers Primary Consumers Secondary Comsumers Tertiary Consumers
  8. 8. Primary Consumers  Plant Eaters  Example: Rabbit eating grass
  9. 9. Secondary Consumers  Carnivores-Meat Eaters  Animals that eat herbivores  There are few top carnivores (e.g. eagles, hawks, tigers, sharks).  Top carnivores are the first to suffer when the ecosystem is disrupted.  These species are vulnerable to extinction.  Example: Snake that eats rabbits
  10. 10. Tertiary Consumers  An organism that feeds on secondary consumers.  Example: A hawk that eats owls
  11. 11. Human Interference  Habitat disruption or degradation disrupts primary productivity.  Humans are at the top of the pyramid and become vulnerable whenever lower trophic levels decrease.  The ability to grow green plants limits the number of consumers.
