Scientists use specific levels of organization to analyze the biosphere. which level of organization is seen in both a school of anchovies and a gaggle of geese? a. ecosystem. b. community. c. population. d. biome

The correct answer is C. population

In biology,the term population signifies a group of individuals of the same species that live in the same place and are able to successfully reproduce among each other. Like in our example with the school of anchovies and a gaggle of geese.

A community is formed by multiple populations of the same species in an ecosystem. Therefore, 3 different gaggles of geese, or schools of anchovies would form a community of geese or anchovies.

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.
