Look at the food web below. What would happen if the grains died out?
Is this an example of high or low biodiversity?

A. Mice would die out and there would be less food for all the rest of the animals in the food web. This is an example of LOW biodiversity.

B. Foxes would die out BUT there would be more food for all the rest of the animals in the food web. This is an example of LOW biodiversity.

C. Mice would have more food but the rest of the animals would starve. This is an example of FAIR biodiversity.

D. Owls would die out and there would be less food for all the rest of the animals in the food web. This is an example of HIGH biodiversity.

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.
