Food Chain: Energy Flow

If the bearded dragon eats live insects, what would it be considered?

• Consumer 

• Producer

What is a food chain?

• The feeding relationship from one organism to an another in an ecosystem (transfer of energy)

• The life span relationship of all organisms in an ecosystem 

What are the four basic levels in a food chain? (According to this video)

• producer, herbivores, carnivore, decomposer

• producer, predator, prey, sunlight

• producer, herbivore, carnivore, omnivore

• predator, prey, herbivore, scavenger

The arrows in a food chain or food web show the direction of energy transfer from one organism to the next.

• True 

• False

What is an herbivore?

• an organism that eats only meat

• an organism that eats only plants or producers

• an organism that eats both plants and animals

What are carnivores?

• organisms that eat only meat

• organisms that eat only plants and producers

• organisms that eat both plants and animals

What do decomposers do?

• They make their own food.

• They eat plants.

• They break down dead organic matter.

Where do decomposers transfer their energy?

• back into the soil, for producers to use

• back to the sun for producers to use.

Each organism in the chain depends on another organism.  A simple food chain is as follows:

sun-> grass -> rabbit -> wolf

What would happen of all the rabbits were killed?  

• The sun and the grass would all die.

• The wolves would decrease in their numbers.

What is the energy source for all organisms in a food chain?

• Plants

• Animals

• The sun
