Pioneer species survive by living on rocks and minerals. select the best answer from the choices provided t f

The given statement is true.  

The pioneer species refers to the hardy species that are the first to spread on to the previously destructed or disrupted ecosystems. They start a chain of ecological succession, which eventually results in a more bio-diverse steady-state ecosystem.  

Let us consider the example of an area affected by a volcano eruption. In such cases, all the vegetation gets destroyed, and even after the cooling and hardening of lava, it would not be easy for the plants to thrive due to the absence of soil.  

In such instances, the ecological succession initiates by the introduction of certain pioneer species like fungi, bacteria, and lichens. These pioneer species possesses the tendency to thrive on rocks and minerals.

explanation:

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
