Food Chain Who can tell me what a food chain is?
What is a food chain? n n Shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link.
Food Chain vs. Food Web Who can tell me what the difference between a food change and a food web is?
Chains vs. Webs n A food web is several food chains put together that show many different organisms and their source of food/energy.
Chains vs. Webs
What is the source of energy for all food webs?
Producers n n Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water. Autotroph: Organism that produces its own food (plants)
Consumers n n Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers.
Consumers There are three groups of consumers. n n n n Animals that eat ONLY PLANTS are called herbivores (or primary consumers). carnivores that eat herbivores are called secondary consumers carnivores that eat other carnivores are called tertiary consumers e. g. , killer whales in an ocean food web. . . phytoplankton → small fishes → seals → killer whales Animals that eat OTHER ANIMALS are called carnivores. Heterotroph: Organism that must consume (or eat) its food (animals).
Decomposers n Then there are decomposers (bacteria and fungi) which feed on decaying matter.
Using the simple food chain below to describe how energy comes from the sun to the plants and the plants pass the energy to the organisms that eat the plants and the process continues. n n n Sun trees giraffes lions The sun provides energy to the tree, the tree provides energy to the giraffe, and the giraffe provides energy to the lion. This is the flow of energy.
Arrange the following into a food web. (Include arrows and group them by producers, consumers and decomposers)
Ultimate energy source!
Producers: get energy from the sun
Consumers: get energy from producers
Decomposers: Breakdown dead materials – include fungus and bacteria
Trophic Level n step in a food chain or food web. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:

Energy Pyramid n diagram used to show energy is distributed in food chains of food webs. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
Producer n organism that can capture energy from sunlight or chemicals and use it to produce food from inorganic compounds; also called an autotroph. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
Consumer n organism that relies on other organisms for its energy and food supply; also called a heterotroph. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
Decomposer n organism that breaks down and obtains energy from dead organic matter. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
Food Chain n series of steps in an ecosystem in which organisms transfer energy by eating and being eaten. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
Food Web n network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem. Understanding Level: 1 2 3 4 Define (in your own words): __________________________________________________ Draw:
In this food chain, the spiders are – A B C D producers primary consumers competitors secondary consumers

The diagram shows a standard pyramid of numbers that indicates the number of individual organisms in a community. Which of the following situations would form a pyramid showing more consumers than producers? A B C D A small plot with 500 corn plants and 100 grasshoppers One pond with 300 producers and one snake An 11, 000 m 3 lake with 75 fish and one alligator One giant oak tree with 10, 000 insects and 10 lizards
