Now examine the lower panel (butterflies), where the curve continues to rise linearly. what does this indicate about the processes structuring the butterfly community?

a. it suggests that the communities are unsaturated and that the size of the regional pool determines local species richness.
b. it suggests that the communities are becoming saturated and that local processes are likely becoming increasingly important.
c. it does not tell us anything about the relative importance of the regional species pool and local interactions.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

for the points

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
