Science 6- Energy Flow Review

All living things are made of _______, and all living things need _______. 

• matter, plants
• energy, matter
• matter, energy

During ____________, _____________ convert light energy into the chemical energy in sugar molecules. 

• chemosynthesis, consumers
• chemosynthesis, producers
• photosynthesis, producers

How can energy be transferred from one organism to another?

• The energy stored in the molecules of one organism is transferred to another organism.
• The matter stored in the molecules of one organism is transferred to another organism.
• The photosynthesis stored in the molecules of one organism is transferred to another organism.

What is a food chain?

• A chain that shows how heat passes from organism to organism.
• A way of showing how matter and energy pass from one organism to another.
• A representation of all the predator-prey relationships in a community.

What type of organisms are the first step in a food chain?

• Consumers
• Predators
• Producers

Examples of producers:

• flies, fungus, and termites
• plants and organisms capable of chemo or photosynthesis
• lions, deer, and shrubs

What's a food web?

• A representation of all the feeding relationships within a community.
• A way of showing how matter and energy pass from one organism to another.
• A food chain provides a more complete model of feeding relationships within a community.

A food web is made up of 

• one food chain.
• only producers.
• many different food chains.

How does an animal use the energy from the food consumes?

• To fuel its life processes such as respiration, digestion, and growth. And some energy is given off as heat.
• Only to move.
• To grow in weight. 

What does an energy pyramid represent?

• Food pyramids show the different food chains in a community.
• Energy pyramids show the same total matter at all levels.
• Shows the amount of energy available at each feeding level in an ecosystem.
