Unit 2 Ecosystem Pdf Unit 2 ecosystem free download as pdf file (.pdf), text file (.txt) or view presentation slides online. the document summarizes key concepts in ecosystem studies. it defines an ecosystem as a self regulating group of species interacting within a shared environment. Food webs: a complex network of interconnected food chains of different tropic levels in a biotic community is termed as a food web. the complexity of any food web depends upon the diversity of organisms in that ecosystem.
Ecosystem Pdf Food Web Ecosystem Food web • food web can be defined as, "a network of food chains which are interconnected at various trophic levels, so as to form a number of feeding connections amongst different organisms of a biotic community". • food webs are indispensable in ecosystems as they allow an organism to obtain its food from more than one type of organism of. 2 unit 2 ecosystems definition and concept of ecosystem • structure of ecosystem (biotic and abiotic components); functions of ecosystem: physical (energy flow), biological (food chains, food web, ecological succession), and biogeochemical (nutrient cycling) processes. Food web: food web is defined as a network of food chains where different types of organisms are connected at different tropic (food) levels, so that there are no. of options of eating and being eaten at each tropic level. 2.1 objectives after reading this unit, you should be able to: define the concept and components of ecosystem; describe various ecosystems; explain the energy flow, trophic levels, food chains, food webs; and compehend the different biogeochemical cycles. 2.2 ecosystem: definition and concepts.

It includes concepts such as ecosystems, food chains, ecological pyramids, and ecological succession, highlighting the relationships between biotic and abiotic components. In nature, we mostly observe food web as there are many organisms which are omnivores. as a result, they occupy multiple trophic levels. the energy flow is the amount of energy that moves along the food chain. this energy flow is also known as calorific flow. the energy flow in the ecosystem is important to maintain an ecological balance. the. Food chain: a sequence of organisms that feed on each other is known as a food chain. example : grazing food chain : grass→caterpillar→lizard→snake food web: in an ecosystem various food chains are linked together and intersect each other to form a complex network called food web. population & community ecology : it seeks to understand the. Food web. the interlocking pattern of various food chains in an ecosystem is known as food web. in a food web many food chains are interconnected. where different types of organisms are connected at different tropic levels, so that there is a number of opportunities of eating and being eaten at each tropic level.
