Energy Flow TEST

Energy moves _______ the Energy Pyramid as organisms consume their prey.

• Up
• Down

Based on the model, which consumers would receive the greatest amount of energy captured by the producers in their food chains?

• Polar Bear and Arctic Hare
• Ptarmigan and Arctic Bumblebee
• Lichens and Shrubs

Based on the model, which in the apex predator?

• Polar Bear
• Lichens
• Beluga Whale

Marine Food Web

• Crabs, pilchards, blennies
• Euphausiids, sweeps, water fleas
• Tiger sharks, dolphins, octopuses

Grassland food web

• Badgers are top predators because they eat upland sandpipers and beetles.
• A predator-prey relationship exists between beetles and ground squirrels.
• Upland sandpipers are primary and secondary consumers because they eat grasses and grasshoppers.
