Semester Final Review

What is a producer?

• an organism that gets energy from eating other organisms
• an organisms that uses sunlight to make its own food
• an organism that gets energy from eating dead organisms, non-living material or waste
• an organism that uses chemical energy to make its own food

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

• Producers
• Carnivores
• Herbivores
• Top Predator

In the energy pyramid below, which organism has the least amount of energy available?

• Producers
• Herbivores
• Carnivores
• Top Predator

If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

• 10 Kcal
• 1 Kcal
• 100 Kcal
• 1000 Kcal

If these organisms were arranged in a food pyramid, which organism would have the least amount of total energy available?

• coyote
• insect
• lizard
• shrub

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

• Primary Consumers
• Producers
• Decomposers
• Tertiary Consumers

What amount of percentage does the energy decrease as it goes up the pyramid?

• 100%

• 1000%

• 10%

• 1%

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

A bee receives nectar from a flower and carries the pollen to other flowers:

• predation

• parasitism

• mutualism

• commensalism
