interaction of pond ecosystem and grassland ecosystem

An ecosystem is a self sustaining structural and functional unit of the biosphere. The ecosystem may be large or small. In the biosphere several ecosystems exist. Usually there is exchange of material and energy between adjoining ecosystems. Ecosystems..

An ecosystem may be natural (like forest, lake, ocean etc) or man-made (such as an aquarium, a crop field etc), temporary (like a rainfed pond) or permanent (like a lake, forest, etc), aquatic (such as pond, ocean etc) or terrestrial (like grassland, forest, ..

Summary - The biotic and abiotic components form an interacting system called 'ecosystem'. Producers, consumers and decomposers are the various trophic levels, which are linked by their food relationship forming a 'food chain'. Several food chains are interrelated and interconne..

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 wate..

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 r..

Interaction Between Members of a Species - In nature there is always a kind of interdependence between different kinds of living organisms among themselves and also between biotic and abiotic components of ecosystem. Competition occurs among individuals of the same species for s..

Grazing food chain is generally seen in ecosystems such as grassland, pond or lake where a substantial part of the net primary production is grazed on by herbivores (cattle and rodents). Usually upto 50% of the NPP is grazed on by these animals in their respectiv..

>Pyramid of Numbers in a Aquatic Ecosystem So, the producers are smallest sized but maximum in number while, top carnivores are larger in size but lesser in number, so these cannot be used as prey by another. Hence the pyramid of numbers is uprigh..

Types of Food Chains - There are mainly two types of food chains operating in nature. a) Grazing food chain b) Detritus food chain. Grazing food chain is generally seen in ecosystems such as grassland, pond or lake where a substantial part of the net primary production..

Food chain studies help, a) understanding the feeding relationships and the interaction between organisms in any ecosystem. b) comprehend the energy flow mechanism and matter circulation in ecosystems. c) understand the movement of toxic substances and the problem of '..
