What is biomass?
300
The role of the alfalfa and grass in your given food web.
What are producers?
300
Plants release oxygen into the air and take in carbon dioxide. Animals take in the oxygen from the plants and give off carbon dioxide.
What is the carbon/oxygen cycle?
300
The year and number that hare reaches its highest population count.
What is 1865 and 150,000 hares?
300
The behaviors and physical characteristics that allow organisms to live successfully in their environment.
What is adaptation?
300
In general, which of the following is a true statement about population size? a. If birth rate < death rate, population size increases. b. If death rate < birth rate, population size decreases. c. If birth rate> death rate, population size increases. d. If death rate> birth rate, population size increases.
What is c? If birth rate > death rate, population size increases.

The mouse plays two roles in the food web I gave you.
What is a first level consumer and second level consumer.
400
This element makes up about 78% of air.
What is nitrogen?
400
Compare the lynx and hare population over the 90 year time span. Use words like increase and decrease as explain.
As the hare population increases so to does the lynx population and when the hare population decreases so to does the lynx population.
400
The smallest level of organization in an ecosystem.
What is an organism?
