Energy Transfer

What is a food chain?

• The flow of energy from one thing to another

• The way animals eat each other

• The way the sun makes everything

• How the plants grow

What is a producer? 

• Organism that creates their own food.
• Organism that eat other organisms for energy
• Organism that eat other dead organisms

What animal is on the top of the food chain? 
*Remember Humans are on the top of all food chains because we do not get hunted. 

• Grass
• Grasshopper
• Mouse
• Owl

An example of a predator:

• shark

• mouse

• rabbit

Where does the energy start in this food chain?

• Plant
• Sun
• Deer
• Wolf

What is the role of a producer?

• Use sunlight to make food
• Gain energy from eating other organisms
• Keep other species from overpopulating
• Breaking down dead stuff 

Which of these is true about this food web?

• The Owl gets its energy from the producer.
• The Lion gets its energy only from a wild cat.
• The Kite gets its energy from the goat.
• The Mouse is most likely to die, several ways.

If the RABBITS became diseased, which organisms would also be POSITIVELY affected?

• Grass

• Snakes

• Nobody (all hurt)

• Hawks

Why are the lower levels of the energy pyramid bigger than the top levels?

• The bottom is for larger animals.

• The bottom levels don't need as much energy.

• The top levels get energy (eat) the lower levels.

• The top levels have fewer predators for they are smaller.

What is the effect of removing prey from a food chain?

• All predators above them will die or suffer.

• The prey's predator will die or suffer, but everybody else should be fine.

• The prey will always, eventually, come back

• The predators population will grow
