Answer:
a. granite, andesite, basalt
Explanation:
There are three basic different types of magma: rhyolithic, andesitic, and basaltic. These three types of magma have different properties which differs them from one another, and which cause different types of eruptions. The rhyolithic (granite) magma has very high viscosity. This magma is the thickest, managing to trap gases in it, and because of it it causes highly explosive eruptions. The andesitic magma is moderate in viscosity, and it has explosive eruptions, but also has lava flows that are relatively slow, so it is very unpredictable what kind of an eruption will the volcano have. The basaltic magma is the least viscous. This means that the eruptions of these volcanoes are not explosive, but instead they produce thin lava flows that cover the surrounding area.

Answer:
A. amount of solar energy available
Explanation:
- The size and type of organisms that can afford to live in the environment is guided by all the following types of systems as compared to the solar energy available at the outer surface of the earth thus energy when reaching on the earth's surface is converted and then it reaches to the organisms.
- Hence the amount of entropy and size of the plants is directly related to the development and growth of types of organisms on earth. As various relationships exist within the ecosystem and are there are competition and there a link within the predation, mutualism, and parasitism.
- Thus the type of environment where the organism develops and sustains will be defined by its physical and chemical habitats.
