In a well-balanced ecosystem, squirrels eat nuts, raccoons feed on squirrels, and bears feed on raccoons. it was observed that there were more squirrels and fewer raccoons. this situation indicates that (blank) 1.squirrels are at a lower trophic level then racoons 2. higher trophic lever 3. the same trophic

The correct answer is 1. squirrels are at a lower trophic level than raccoons

In the question a food chain is given:

Plants producing nuts -- squirrels -- raccoons -- bears

In the above food chain nuts producing plants are producers, squirrels are primary consumer, raccoons are secondary consumer and bears are top consumers. The feeding relationship can be graphically represented in the form of a pyramid. In a pyramid the number of organisms is highest at the base and is number of organisms get reduced as we move towards the apex of the pyramid. In the given food chain, squirrels occupies lower level than the raccoons in the pyramid. Thus, the squirrels are more in number than raccoons.  

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.
