4.2 Energy Flow of Ecosystems

The amount of energy that usually transfers from one trophic level to the next...

• 10%
• 20%
• 80%
• 50%

An illustration that uses arrows to show the many possible directions in which matter and energy can pass through the organisms in an ecosystem.

• Food chain
• Food web
• Energy Pyramid
• Succession Map

The shrew provides energy for the _______?

• cricket
• grasshopper
• frog
• snake

Which of the following is a herbivore?

• cricket
• frog
• hawk
• shrew

In the energy pyramid here, which organisms have the most energy available?

• Producers
• Carnivores
• Herbivores
• Top Predator

What are plants called in a food chain?

• Producers
• Consumers
• Decomposers
• Scavengers

What are animals called in a food chain?

• Producers
• Consumers
• Decomposers
• Plants

An energy pyramid represents what?

• How much sunlight is available for the ecosystem to use. 
• How much energy a particular organism needs. 
• How much energy is needed to build a pyramid. 
• The amount of energy available to the next 'feeder' in a food web.

Why might an organism have more than one arrow coming from them in a food web?

• More than one organism may eat them. 
• They may eat more than one other organism. 
• This organism gets its energy from multiple sources. 
• They have no resources available to them.

The largest group of organisms found in a food web would be:

• Primary Consumers
• Producers
• Decomposers
• Tertiary Consumers
