Unit 10 Review Game (symbiosis, energy flow pyramid, levels)

A wolf is chasing a rabbit. The prey does not escape its predator. What is this relationship?

• Parasitism
• Predation
• Commensalism
• Mutualism

A flea is living on a cat and obtains nutrients from the cat's blood. The cat becomes sick and its skin is irrated.

• Parasitism
• Predation
• Commensalism
• Mutualism

A species of bacteria lives in the gut of a fish and feeds off the food the fish eats. Meanwhile the fish is not affected by this bacteria.

• Parasitism
• Predation
• Commensalism
• Mutualism

A sloth is covered in algae that lives in its hair and helps the sloth blend into its environment. In return, the algae gets shelter and exposure to sunlight as the sloth climbs higher in the trees.

• Parasitism
• Predation
• Commensalism
• Mutualism

Mosquitoes carry microorganisms that cause malaria (a disease). Mosquitoes do not get malaria, but when mosquitoes bite humans the microorganisms are transferred to humans, causing the human to get malaria. What is the relationship between the microorganism and mosquito?

• Parasitism
• Predation
• Commensalism
• Mutualism

Why does each level of the energy pyramid get smaller when moving up the pyramid from one level to the next higher level?

• Energy is evenly distributed among all levels of the pyramid.
• Only a small, limited amount of energy is present for organisms in their ecosystem.
• The energy is mostly found at the top of the pyramid where the energy is concentrated.
• Just a small amount of energy from one level is available to the organisms that are one level higher.

What is the importance of bacteria in this food chain?

• Bacteria perform photosynthesis to give other organisms oxygen
• Bacteria perform cellular respiration by using oxygen and water to make carbon dioxide
• Bacteria make energy from water
• Bacteria decompose organic material so that nutrients can be reused
