Most food chains start with a producer, go through consumers, and end with a decomposer. Why are decomposers so important in the cycle of life? There are four organisms you'll research for this assignment. Answer the questions in the chart. Then create a food chain for each organism.
1. In which ecosystems would you find this organism (choose one if you find multiple ecosystems)?
2. What does this organism eat or how does it get its energy?
3. How does this organism return nutrients to the ecosystem?
4. Write an example of a food chain that includes this organism. (It does not have to be the end. Example: dead animal à flies and maggots à
frog)
5. Include a citation for each source used in the second table.

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
