Which type of rock does a represent?

Rock formed by cooling

Explanation:

Rock A represents a magmatic rock that was formed by cooling and solidifying the magma that was expelled from a volcano.

The cooling of the magma is capable of generating rocks rich in crystals in its composition. Most crystals are not visible to the naked eye, but make up the rock in its entirety, when cooling occurs on the earth's surface. When cooled inside the earth, magma also forms rocks rich in crystals, which in turn are visible to the naked eye.

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
