Read this and answer the question below it: The alpine community data that you will be using today was collected from Rocky Mountain National Park in the

Western United States. This is a mountainous region, with altitudes of 10,000 or more in some places. The climate in

Rocky Mountain National Park is often cold, snowy, and windy. As you travel up the mountain, the temperatures

decrease and wind increases. Summer temperatures can be warm, around 50°F, while winter temperatures can reach

well below freezing. At high altides, there is less oxygen available in the air. The thin air and extremely harsh

conditions in the alpine biome require plants and animals to have special adaptations like thick fur and hibernation)

to help them survive the difficult conditions.

Pre-lab Questions

1. What are some important characteristics about the Rocky Mountain National Park in you're own words?

Abanana plant produces rhizomes, which are involved in

How energy flows through each level in this energy pyramid. is all the matter and energy from one level transferred to the next level?

On a backpacking trip, kenny hikes all day at a steady pace, covering 30 kilometers and burning 4000 calories. at the school track, janelle runs the 100-meter sprint in 13.5 seconds, burning 10 calories. afterward, janelle’s leg muscles are aching and she is breathing hard, while kenny maintains normal breathing all day, even though he burns 400 times more calories than janelle. which two statements offer the best explanation for this phenomenon? a. if the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt." b. aerobic cellular respiration produces more energy, but its use is limited because of lactic acid buildup in the muscles and the resulting "oxygen debt." c. after about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce atp, resulting in "oxygen debt." d. the rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
