Answer:
The correct answer will be- such as poor water management and nutrient management leads to 70-90% reduction in the yield.
Explanation:
The productivity of the crops is directly influenced by both biotic factors and abiotic factors.
The factors which are living and reduces the yield of the crops creates biotic stress like pest and disease which result in 10-30% loss in the yield o crops.
The factor which is non-living and creates stress for the crops is known as abiotic stress like poor water and nutrient management which leads to the loss of 70-90% productivity.
Answer:
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.
