An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

WHAT IS ECOSYSTEM An ecosystem consists of the biological community that occurs in some locale‚ and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems -- a pond‚ a forest‚ an estuary‚ grassland. The study of ecosystems mainly consists of the study of certain processes that link the living‚ or biotic‚ components to the non-living‚ or abiotic‚ components. Energy transformations and ecosystem components are the two main topics

effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where ATP

Internally in the human body‚ has to be well-controlled and organised with different progressive systems in which they must interconnect and interrelate in order to perform their role efficiently and successfully. There are different types of systems in the body (mainly 10) in which they all function in different ways and interrelate. An example would be the

There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes linked to the

Introduction Ecosystem is similar to a community. It consists of species‚ living organisms and the abiotic factors‚ their habitat. Living organisms includes animals‚ plants‚ insects‚ micro-organisms. For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water. Over-breeding is the increase of offspring of a species to a excessive number

Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka‚ Diaz and Villa‚ 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates‚ such as glucose‚ is a fundamental part of cellular respiration (Mader‚ 2009). As a catabolic process‚ it may or may not require the presence of oxygen. The process that requires oxygen is called aerobic

materials both plants and animals take in to grow and prosper. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs
