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 Back to Game

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

Food Web for $300 If you have a food web with mice and hawks and you remove some of the mice, what happens to the numbers of hawks in the population?

What is? The number of hawks decreases in size

What is…? Pyramids This type of pyramid deals with the mass of the organism

Biomass pyramid Good Answer! Back to Game

What is …? Symbiosis This type of symbiosis occurs when one organism benefits and one organism is harmed.

Back to Game Parasitism

What happens to the carbon cycle when there is a lot of development. Ex: cutting down trees and plants What is…? Miscellaneous

Back to Game There will be more carbon dioxide and global climate change

What is…? Breathe In and Out This chemical is put into the atmosphere by volcanoes and consumers

Carbon Dioxide Back to Game

Which chemical is released from cows during respiration What is…? Breathe

What is ? Carbon Dioxide

This type of symbiosis occurs when both species benefit What is..? Symbiosis for $300

Back to Game Mutualism

Carbon dioxide Back to Game

What is…? In an energy pyramid, which group has the most available energy? Pyramids

producers Back to Game

What is…? Respiration occurs in which of the following? Cats, fruit trees, rabbits

cats, trees, rabbits Back to Game

What is…? What’s the last organism in a food web energy transfer?

Decomposers, bacteria, fungi Back to Game

Why are elements such as carbon not removed from the biosphere? What is…? Double the Money!!! Woohoo!

Because they are recycled Back to Game

What is…? What would happen to the process of photosynthesis if producers were removed? What is…?

Back to Game There would be a decrease in energy produced in the ecosystem

What is…? Trophic Levels At the first trophic level there are 6,000 kcal/yr burned. How much energy is burned at the third level?

Back to Game 60 kcal/year

What is…? How is atmospheric nitrogen converted so that animals can use it?

Back to Game By bacteria in the soil

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 Back to Game

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.

What is…? In an ecosystem a pyramid of numbers measures what? AND>>>…… what trophic level are the smallest number of organisms found?

Gives the number of organisms in the ecosystem, Found at the top trophic level Back to Game

What is…? Why is the smallest number of organisms found at the top trophic level?

There is less energy available Doofus! Back to Game

What is…? Factors or nutrients that can affect the size of a population, Hint: May also cause algae blooms

What is a limiting factor? Back to Game

What is…? This nutrient is found mostly in rock/soil

phosphorus Back to Game

What is…? How is carbon recycled back into the soil and water?

Back to Game decomposers

What is…? What is this chemical C6H12O6?

Back to Game Glucose/sugar

What is…? Misc for $500 What is the name of this chemical NH4?

Back to Game ammonia
