12 Questions with Answers and Explanations on “Ecosystem” for Biology Students: Image Source: cnx.orgQ.1. What are the two basic categories of ecosystem? Give two examples to each.Ans. ADVERTISEMENTS: TerrestrialEx- GrasslandForest ADVERTISEMENTS: AquaticEx- PondWetlandQ. 2. Describe the components of an ecosystem. ADVERTISEMENTS: Ans. Ecosystem consists of abiotic and biotic components.Abiotic components: These components are the non-living components. Light, temperature, soil, water are the abiotic factors that make the habitat for living beings.They affect the living organisms behaviour and physiology. The survival of living organisms is directly or indirectly effected by these factors and thus they are dependent on it.Biotic components: These are the living components. Plants and animals.They live in a habitat and show inter dependance on each other and on the abiotic components.The components of the ecosystem are seem to…

Here is your essay on the Most Important Physical Properties of Water !Water is an extremely inert body in relation to most other chemical substances. It contains following unique physical pro­perties which have ecological relevance: image source: goodwp.com 1. Specific Heat: Water is capable of storing tremendous quantities of heat energy with a relatively small rise in temperature. In this pro­perty, it is exceeded only by ammonia, liquid hydrogen and li­thium. Thus water is said to have a high specific heat which can be defined as the number of calories necessary to raise one gram not water one degree centigrade. The specific heat of water is given the value of 1. ADVERTISEMENTS: Because such great quantities of heat are absorbed be­fore the temperature of natural waters such as ponds, lakes…

Essay on Theoretical Approaches towards The Concept of Climax Community !The concept of climax long was a subject of much controversy and discussion. There are following three theoretical approaches to the climax: 1. Monoclimax theory: This theory is developed largely by Frederick Clements. This theory recognizes only one climax, determined solely by climate, no matter how great the variety of environmental conditions is at the start. All seral communities in a given region, if allowed sufficient time, would ultimately converge to a single climax. ADVERTISEMENTS: The whole landscape would be clothed with a uniform plant and animal community. All other communities than the climax are related to the climax by successional development and are recognized as sub climax, disclimax, preclimax, post-climax and so on. image source: jpkc.scau.edu.cnA subclimax is a…

Here is your Short Speech on Ecosystem !A classic example of an ecosystem is a small lake or pond the abiotic or non-living parts of a freshwater pond include the water, dissolved oxygen, carbon dioxide, inorganic salts such as phosphates, nitrates and chlorides of sodium, potassium, and calcium, and a multitude of organic compounds such as amino acids, humic acids, etc.The living part of the freshwater pond can be subdivided according to the functions of the organisms, i.e., what they contribute toward keeping the ecosystem operating as a stable, interacting whole. image source: i.ytimg.com ADVERTISEMENTS: In a freshwater pond there are two types of producers, the larger plants growing along the shore or floating in shallow water, and the microscopic floating plants, most of which are algae, that are distributed…

Essay on Soils Fauna and Soil Flora !Soil supports a wide array of organisms of different body-sizes and taxonomic groups. Generally, soil organisms are classified into three major groups namely micro-fauna and micro-flora, meso-fauna or meio-fauna, and macro-fauna. image source: pasowinerealestate.com ADVERTISEMENTS: Mesoflora and macroflora because occur above the surface of soil (land-surface), therefore are ex­cluded from this discussion: 1. Microfauna: It includes animals with body size within the range of 20 µ to 200µ. It includes all Protozoa and small-sized mites, nematodes, rotifers, tradigrades and copepode Crustacea. Soil inhabiting protozoans like amoeba, ciliates, zoomastigine flagellates occur near the surface soils, while the testate forms like Thecamoeba, Euglypha and Difflugia, have a wider vertical distribu­tion.The common terrestrial polyclad is Bipalium. The nematodes such as Rhabditis, Diplogaster, Tylenchus, Heterodera, Aphelen- choides,…
