The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
The UV rays cause sun spots due to reaction from the radiation.
The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.
Explanation:
In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.
The sea-level got drop due to global cooling of that time.
This resulted in continental drift making land connection of Africa with Eurasia.
The primates started migrating through this route.
The African forest become dry causing selective pressures in primates.
The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.
The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
