Which of the following supply energy TO the bear?

• Beaver

• Parasol Fungus

• Swallowtail Caterpillar

• Persimmon Tree

In this food chain, what will happen if the frogs become extinct?

• The snakes will increase.
• The grasshoppers will decrease.
• The eagles will remain the same.
• The grasshoppers will increase.

Grizzly bears eat seeds, berries, roots, grasses, fungi, deer, elk, fish, and insects. This would make them a(n)...

• Detritivore

• Carnivore

• Herbivore

• Omnivore

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

• Carnivores

• Herbivores

• Top Predator

Answer explanation

The organisms closer to the base of the energy pyramid have the most energy available to them. These organisms are typically the primary consumers, such as herbivores, which feed on the producers (plants) at the bottom of the pyramid.

Which organism recieves the least amount of energy from the producer?

• Owl

• Grasshopper

• Lilypad

• Mouse

Answer explanation

The organism that receives the least amount of energy from the producer is the organism at the top of the energy pyramid. This is because energy is lost as it moves up the food chain, so the organism at the end of the chain receives the least amount of energy from the producer.

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

• Producers
• Herbivores
• Carnivores
• Top Predator

In the energy pyramid, what comes after the producers?

• Producers

• Primary Consumers

• Secondary Consumers

• Tertiary Consumers

How do producers create their own food?

• Through photosynthesis

• Through magic and imagination

• by eating the sun

How would the removal of earthworms from the food chain affect the other organisms?

• The number of bass will increase.

• The number of crayfish will decrease.

• The crayfish will get their energy directly from the sun.

• The number of bass and ospreys (bird) will increase.

Which organism has the least amount of energy available to it?

• Wolves

• Foxes

• Rabbits

• Grasses
