ECOLOGY AND ECOSYSTEM (Definition, Type, Components and Function)

ECOLOGY AND ECOSYSTEM (Definition, Type, Components and Function) ECOLOGY The term ecology was coined by Earnst Haeckel (1869). The study of ecosystem is defined as Ecology. Therefore ecology deals with the study of organisms in their natural home interacting with their surrounding. ECOSYSTEM The term ecosystem was coined by a British ecologist A. G. Tansley (1935). Ecosystems is a self regulating, self sustaining and functional unit of nature where living organisms (biotic component) interacting with each other and with their non living environment (abiotic factor) exchanging energy and matter. Types of Ecosystem- According to environment- 1. Terrestrial Ecosystem -   A terrestrial ecosystem is an ecosystem found only on landforms. Six primary terrestrial ecosystems are tundra, taiga, temperate deciduous forest, tropical rain forest, grassland and desert. 2. Aquatic Ecosystem -  An aquatic ecosystem is an ecosy

ECOLOGICAL PYRAMID

Image
ECOLOGICAL PYRAMID Ø   The use of Ecological Pyramid was first described by Charles Elton in 1927 . Ø     Ecological Pyramids are graphical representation of the number of individual present or amount of biomass synthesized or amount of energy stored at successive trophic levels in an ecosystem. Ø   Ecological Pyramids are starting with producers at the base and successive trophic levels forming the apex are known as an Ecological pyramid. Types of  Ecological Pyramids- Pyramid of numbers- Ø   Graphical representation of numerical strength of various populations in different trophic levels per unit area of an ecosystem. Ø   Usually upright. Ø   Inverted and spindle shaped only in some parasitic food chain and tree ecosystem. 2.  Pyramid of Biomass- Ø   Biomass is the total weight of living matter per unit area. Ø   In terrestrial ecosystem, Biomass decreases from the producer level to the consumer level. So, the pyramid of biom

Remote sensing

What is Remote sensing Remote sensing is defined as the art and science of obtaining information about an object without being in direct physical contact with the object. It is a scientific technology that can be used to measure and monitor important biophysical characteristic and human activities on earth. Remote sensing is also defined as the measurement or acquisition of information of some property of an object or phenomenon, by an recording device that is not in physical or intimate contact with the object or phenomenon under study. So, remote sensing is the non contact recording of information from the ultraviolet, visible infrared and microwave region of the electromagnetic spectrum by means of instrument such as cameras, scanner, laser, linear arrays and area arrays located on platforms such as aircraft or spacecraft and the analysis of acquired information by mean of visual and digital image processing .(Jensen J. R.M 2014) The sensors collect data in the form of
