Question

The word ‘standing state’ in ecosystem refer to
A. Living component
B. Non-living components
C. Both living and non- living components
D. None of the above

Answer 1

Hint: Standing state is the amount of inorganic nutrients like nitrogen, carbon, potassium present in soil at specific time. It tells the productivity of the ecosystem at a specific time.

Complete answer:
An ecosystem is the functional unit which is made up of all the organisms in a specific place so that they can interact with one another and with the environment. It is made up of living components (biotic) and non -living components (abiotic). Abiotic components include the physical and chemical factors. Physical factors include light, air, soil etc whereas chemical factors include salinity, moisture content etc. Biotic components are classified based on whether they produce their own food (autotroph) or cannot produce their food (heterotroph).
Standing state is the amount of nutrients present in the soil in a specific time. It describes the nonliving matter and it rotates around the living and non -living matter components of the ecosystem. It is regularly drained and replenished by the living matters. It takes place in the growth medium of producers and describes the productivity of an ecosystem. It depends on the season and various kinds of ecosystem whereas Standing crop is the total dried biomass that is present in an ecosystem. It is a crop grown especially for cereals. The standing crops can be changed depending on the monsoon,

Therefore the correct answer is B

Note: The two terms which help in the classification of ecosystems into biotic and abiotic factors are standing state and standing crop. Standing state is the number of inorganic nutrients present in the ecosystem constituting the part of non -living components and it is refilled by living matter. Standing crop is the biomass that is a living organism which exists in an ecosystem.
