Food Web for $100

You have a food web with bushes eaten by deer and deer eaten by mountain lions. What type of organism is responsible for recycling

matter back into the soil?

What is…?

Decomposers

What is..?

Food Webs for $200

Explain how energy is transferred from a plant to a

butterfly. Include the amount of energy available at each level

Back to

Game

Energy is transferred from the plant to the butterfly with less energy being available to the

butterfly

Why are elements such as carbon not removed from the biosphere?

What is…?

Double the Money!!! Woohoo!

Because they are recycled

Back to

What is…?

What type of symbiosis is it?

This type occurs when one organism benefits but there is no benefit or harm to the other organism

commensalism

What is…?

Competitive Exclusion Principle

This principle states that no 2 species

shall….

Occupy the same niche

Back to

Game

What is…?

Competition

You want to test the effect of competition within one particular species of snails. How would you set up an aquarium to test this?

(Hint: food and snails)

Back to

Game

Set up one aquarium with a number of snails

and less food than they need to eat.

Back to

Game

What is…?

Why is the smallest number of organisms found at the

top trophic level?

There is less energy available
