Accuracy describes how well a measuring instrument determines the variable it is measuring. How close the value is to real value. The level of accuracy of measuring tool determines the detail to which it can measure. In order to be accurate in their work scientists need first select a measuring instrument that allows an appropriate measure of accuracy and then to calibrate it. Calibrating an instrument involves measuring already known quantities to check how accurately it is. In the laboratory accuracy of a test is determined when possible comparing results from the test in question with results geenrated from an established reference method.

Explanation:
In ecology, biomass refers to the mass of organisms living within a specific region at a time. Biomass is measured and usually described as:
- the total mass of the organisms within a community
- the average masses per unit area
Typically, more numerous organisms, such as producers, have a higher average biomass. This may include plants, animals or microbes such as bacteria and fungi. In terrestrial environments, biomass is distributed in pyramid form; the carnivorous hawk preys on rabbits and birds, which are nearer to the base of the pyramid- each predator population would have a lower biomass than its prey.
The birds weigh 100 grams while the rabbit weighs 150 grams.The rabbit has a higher total mass
