Agriculture, an important part of Georgia life, is a threat to the fish populations throughout the state's freshwater habitats. All BUT ONE situation is a negative consequence of agriculture on the freshwater fish species in Georgia.
A)
Cattle access points contribute to sedimentation and nutrient pollution.
B)
Reducing water demand to prevent the need for constructing new
reservoirs.
Suspended sediment decreases water clarity and interferes with sight-
feeding and other visually oriented fish.
D)
Nutrient pollution from fertilizer runoff and animal waste can lead to algal
blooms, which in turn may affect water clarity and dissolved oxygen levels.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

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.
