The areas of the hydrosphere, the biosphere and the lithosphere Essay

The areas of the hydrosphere, the biosphere and the lithosphere - Essay Example Energy gains, on the other hand, are highly influenced by human activities such as building of irrigation and dams. Water, in the form of snow and rain, falls on earth to be absorbed by bodies of water and plant fields (Bharatdwaj, 2009). Gabler, Petersen & Sack (2011) explained that when water reaches the subsurface, it goes first to the zone of aeration where air occupies most space. Water then consumes the space in the zone of saturation which is topped by water table (Gabler et al., 2011). Groundwater wells are designed to alter nature’s way of keeping water beneath the surface (Bharatdwaj, 2009). Cones of depression in the water table evolved from constant extraction of water from wells. When several cones of depression meet, other nearby shallow wells runs out of water (Gabler et al., 2011). Another indispensable process that sustains life is the food web. It is a series of food chains interlinked with one another. The food chains’ prequel is the primary producers supplying the essential energy for food (Bharatdwaj, 2009). Food chain is facilitated by primary consumers that feed on plants, the secondary consumers that feed on the primary consumers and then there are the decomposers that feed on what is left in each process of the cycle (Bharatdwaj, 2009). A clear cut example of a food chain is when grass was feed on by a cow; consequently the cow is eaten by man. In the study of these organisms, a biologist focuses on the processes that propels life itself, whereas, the focus of a geographer is to identify ways to preserve and maintain the Earth’s surface and resources. The diversified community of plants and animals that cover a specific area and own a particular climate are termed as biomes (Kaufman & Marsh, 2012). Biomes are like zoogeographic regions w hich aim to classify the distribution of Earth. But unlike biomes, zoogeographic regions
