C. Ecosystem
 
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.   

Yes, large temperature and precipitation have differences over small areas due to elevation differences.

Explanation:

Elevation or altitude has a great impact on the amount of temperate and precipitation. If the elevation or altitude increases, the temperature becomes decreases and the amount of precipitation increases. This type of change in temperature occurs when we go from the plain areas to the mountainous areas. The temperature of plain areas is high with less amount of precipitation while the temperature of mountainous areas is low with high rate of precipitation. So we can say that elevation differences cause fluctuation in temperature and precipitation of an area.
