Species richness increases Select one: a. as we increase in altitude in equatorial mountains. b. as community size decreases. c.
olga55 [171]

Answer:

D) as we travel southward from the North Pole.

Explanation:

Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.

Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.

Rzqust [24]

The answer would be B:The data suggests that exercise increases the rate of cellular respiration because more carbon dioxide was produced.


The data has a consistently show that the time needed to change BTB color in after exercise group is much shorter(less than half) compared to before exercise group. If the time needed longer, this show that the amount carbon dioxide removed from the lungs is much higher. The reaction that provide energy for the muscle will produce carbon dioxide as side product in cellular respiration.
