1. What are the tropics of capricorn and cancer?

2. Why are lichens and moss the first vegetation to arrive during primary succession?

one species cannot survive without the other like the leaf cutter ants and fungusThe soil quality for them isn't really important. Then, as soil quality improves from decomposition of dead organisms, more diverse plant life will be suited to live in the better soil.The tropics of Cancer and Capricorn are 23.5 degrees North and South of the Equator, respectively. Since the Earth is tilted in its rotation, they actually are in the 'middle', and they subsequently get the most lightWhen food is low and weather is bad, moose decrease in population. When food is plentiful and weather is good moose increase in population. When they increase, predation increases and decreases their population. Therefore, both environmental conditions and predation cause moose population to decrease.
