Which of the following can be accurately said about climax communities?

a. restoration of the original climax community is always achieved at the same rate.
b. climax communities are always stable.
c. climax communities are always uniform.
d. restoration of the original climax community may not always happen.

The climax community can be defined as the community which is stable and has reached the stage from where no further succession occurs. The community of animals, plants and fungi which by the process of ecological succession in an vegetative area have reached a state which is stable over time, is known as the climax community. It is difficult to restore the original climax community, and the process may not always happen.

Hence, the correct answer is 'Option D'.

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.
