(02.04 hc)list an example of how an ecosystem can be affected by weather patterns. explain how ocean temperatures affect weather patterns.

An ecosystem is defined as the group of biological community in which the organisms interacts with the physical environment. They are mainly of two types, such as- the terrestrial ecosystem and the aquatic ecosystem. This two are further subdivided into different types.

These ecosystems are directly related to the weather and climatic conditions. A change in the weather or climate pattern will directly have an impact on the organisms that lives in these ecosystem.

For example, the freshwater ecosystem is rich in a variety of aquatic species. In a region where there is sufficient rainfall and temperature, there the organisms will exists without any difficulties. But, if the temperature in that area increases rapidly and there occurs heavy rainfall, then these river waters will spread in every possible direction due to their higher flow rate, resulting in flood and affecting the aquatic species. So the weather plays an important role in controlling the ecosystem.

The earth is comprised of nearly 70% of water bodies that includes the oceans, seas, rivers and lakes. This oceans in the equatorial region receives maximum amount of sunlight, due to which the area becomes warm and forms a low pressure zone, resulting in heavy rainfall. Whereas, towards the higher latitudes, these ocean water remains relatively cold. So the warm air from the equatorial region are carried towards the poles in order to maintain the equilibrium, resulting in various types of weather patterns.

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.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
