The habitats studied by marine biology include everything from the tiny layers of surface water in which organisms and a biotic item

Chapter 3 Ecosystems: What Are They and How Do They Work? Section 3-1: What Keeps Us and Other Organisms Alive? Earth’s life support system has four major components: The atmosphere (air) The hydrosphere (water) The geosphere (rock‚ soil‚ and sediment) The biosphere (living things) The Atmosphere The atmosphere can be divided into two layers: The troposphere extends about 17 km above sea level at the tropics and about 7 km above the north and south poles. It contains the air we breathe: 78% Nitrogen

Food chains‚ Food Webs and the Flow of Energy in Ecosystems Introduction An ecosystem can be defined as a more or less self-contained function unit in ecology consisting of all abiotic and biotic interactions in a specific area. Flow of energy within an ecosystem is a one-way process; Photosynthesis utilizes light (solar) energy to yield chemical energy that is passed on to organisms at significantly reduced amounts at each level of nutrition. This ‘inefficiency’ in energy transfer is the principal constrain

Lake Tahoe is one of America’s deepest‚ freshwater lakes. The iconic vacation spot keeps locals and tourists occupied with ski resorts and casinos. Although‚ there is more to the area than its breathtaking views. The Lake Tahoe Basin is home to many species that contribute to its ecology. Species interaction with biological communities and environment affect the ecosystem greatly because of species dependency of the environment and its resources. This makes it especially difficult with the Lake

Microscopic marine organism such as phytoplankton and zooplankton are highly sensitive to UVB radiation (1). Phytoplankton are single-celled organism‚ as UVB is absorbed by a few layer of cells‚ single celled organisms like phytoplankton lack out layers protection from the radiation (4‚9).
