Given below are two statements :
Statement I : The primary source of energy in an ecosystem is solar energy.
Statement II : The rate of production of organic matter during photosynthesis in an ecosystem is called net primary productivity (NPP).
In the light of the above statements, choose the most appropriate answer from the options given below :
Which of the following is the unit of productivity of an Ecosystem?
In the equation
\(GPP - R = NPP\)
GPP is Gross Primary Productivity
NPP is Net Primary Productivity
R here is ______.
Identify the correct statements :
A. Detrivores perform fragmentation.
B. The humus is further degraded by some microbes during mineralization.
C. Water soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching.
D. The detritus food chain begins with living organisms.
E. Earthworms break down detritus into smaller particles by a process called catabolism.
Choose the correct answer from the options given below :
Given below are two statements :
Statement I :
Decomposition is a process in which the detritus is degraded into simpler substances by microbes.
Statement II :
Decomposition is faster if the detritus is rich in lignin and chitin
In the light of the above statements, choose the correct answer from the options given below :
Detritivores breakdown detritus into smaller particles. This process is called :
In the equation GPP\(-\)R=NPP
R represents :
In relation to Gross primary productivity and Net primary productivity of an ecosystem, which one of the following statements is correct ?
