Which type of symbiosis is shown in the image? The image is a rhinoceros with several birds who are eating insects off of his back.

• Mutualism - both species benefit

• Commensalism- only one species benefits

• Parasitism - one species benefits and the other is harmed

• One is a predator and one is the prey

The scientific name for when one species benefits and the other is harmed is--

• Mutualism

• Commensalism

• Parasitism

• Predator and Prey

The scientific name for when one species benefits and the other is unaffected is--

• Mutalism

• Commensalism

• Parasitism

• Predator and Prey

In this food web, where is the most energy located?

• At the top with the Python, Wolf and Eagle

• At the bottom with the producers

• Spread evenly throughout the food web

• There is no way to tell the amount of energy in a food web

A pyramid shape is used to show the amount of available energy at each trophic level because... 

• energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up. 
• energy increases up the food chain just like the pyramid shape gets smaller as you go up. 
• energy amounts are the same at each trophic level

In this energy pyramid, what is the proper name for ANY ORGANISM ABOVE THE PRODUCER LEVEL?

• decomposers
• consumers
• producers
• omnivores

What makes an energy pyramid different than a food web or chain?

• It shows energy flowing from the top of the chain and downward. 
• The tropic levels are the opposite
• It shows the amount of energy in each trophic level
• It shows specific predator/prey relationships

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

• Producers
• Herbivores
• Carnivores
• Top Predator

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

• Beluga Whale
• Polar Bear and Arctic Hare
• Ptarmigan and Arctic Bumble
• Lichens and Shrubs

All energy on Earth ultimately comes from what source?

• Water
• Sun
• Consumers
• Oxygen
