Answer:
B
Explanation:
Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass.
Nitrogen fixation is the process where atmospheric nitrogen is converted by bacteria into biologically usable forms.
plant can not take nitrogen directly from the leaves.
