What happens to the amount of available energy in the pyramid as it moves up through the different levels? a) it increases. b) it decreases. c) it remains the same. d) it decreases, then increases. elimin

The correct option is B) It decreases

Explanation:

As we move up the trophic levels in an energy pyramid, the energy which is passed from one trophic level to other decreases. Only 10% of the energy is known to pass from one trophic level to another. Most of the energy is lost as heat or used by the organism.

For example, suppose a plant has 100 calories in it. It will pass only 10 calories to the animal ( primary consumer) which eats it. The primary consumer will only pass 1% energy to the secondary consumer which eats it. Hence, we see that to the amount of available energy decreases as we move up the trophic levels.

the correct answer is b

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.
