An ecosystem is defines as an interacting unit that includes both the biological community as well as the non-living components of an area. The living and the non-living components of an ecosystem interact amongst themselves and function as a unit which gets evident during the processes of nutrient cycling energy flow decomposition and productivity. There are many ecosystem such as pnds forests grasslands etc. The two components of ecosystem are:
(a) Biotic component:It is the living component of an ecosystem that includes biotic factors such as factors consumers decomposers etc. Producers include plants and algae. They contain chlorophyll pigment which helps them carry out the process of photosynthesis in the presence of light. Thus they are also called converters or transducers. Consumers or hetrotrophs are organisms that are directly(primary consumers)or indirectly(secondary and tertiary consumers)dependent on producers for their food. Decomposers include micro-organisms such as bacteria and fungi. They form the largest population in a food chain and obtained nutrients by breaking down the remains of dead plants and animals.
(b) Abiotic component:-They are the non-living component of an ecosystem such as light temperature water soil air inorganic nutrients etc.
Given below are two statements:
Statement I: Gause’s ‘Competitive Exclusion Principle’ states that two closely related species competing for the same resources cannot co-exist indefinitely and competitively inferior one will be eliminated eventually.
Statement II: In general, carnivores are more adversely affected by competition than herbivores.
In the light of the above statements, choose the correct answer from the options given below:
In the equation GPP - R = NPP
GPP is Gross Primary Productivity
NPP is Net Primary Productivity
R here is ________.
An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.
The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
There are two main components of the structure of an ecosystem, namely:
The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
