• Producers
• Carnivores
• Herbivores
• Top Predator

Which is the smallest level of an ecosystem?

• organsism
• population
• community
• ecosystem

a system of food chains that shows the transfer of energy  is termed

• food web
• food chain
• prey
• predator

Biodiversity is 

• the variety of species within an ecosystem
• a large number of the same species in an ecosystem
• an abundant amount of the same primary consumers 
• the ability to have an abundant source from the same species

Photosynthesis is important because...

• it makes carbon dioxide

• it makes food for the food webs

• it makes water

• it's not important

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

• Primary Consumers
• Producers
• Decomposers
• Tertiary Consumers

Examples of a producer

• frog
• algae
• worm
• mouse

Example of a decomposer

• fungus
• mouse
• plants
• frogs

How does the energy flow in an energy pyramids?

• up the pyramid

• down the pyramid
