The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its 'species composition' and '..

Introduction - Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and water. The branch of biology, which deals with the relationshi..

An ecosystem can be defined as 'a structural and functional unit of biosphere or segment of nature consisting of community of living beings and the physical environment, both interacting and exchanging materials between them..

An ecosystem can be defined as 'a structural and functional unit of biosphere or segment of nature consisting of community of living beings and the physical environment, both interacting and exchanging materials between them'. E. P. Odum, an American ecologist, defined..

Functions of Ecosystem - In an ecosystem there are two processes proceeding simultaneously: 1 ) Energy flow and 2 ) Biogeochemical cycle The energy flow is in a single direction and is non-cyclic where as Biogeochemical flow is cyclic (Any mineral cycl..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy is transferred to them. Carnivor..

(Organisation or Structural aspect of an ecosystem) An ecosystem comprises of two basic components i) Abiotic components and ii) Biotic components The relationship between the biotic components and abiotic components of an ecosystem is called 'holocoenosi..

Internal View of the Heart The human heart is four-chambered. The upper chambers are called the atria or the auricles and the lower two chambers are called the ventricles. The two atria are separated by the interatrial septum. The two ventricles are separated from each other by the interventricular..
