An ecosystem has many levels of organization. which level will have the most individuals? a. a population b. a biological species c. an interbreeding group d. a community

D. A community

Explanation:

An ecosystem is a biotic community in which living beings interact with their non-living physical environment which includes non-living factors like soil, water and wind. A community is an interacting group of various species living in a same location. For example, forest is an ecosystem which consists of community of species like plants, animals and microbes.

On the basis of the above explanation, the community will have the most individuals.

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.
