Answer – C (Using instruments that have not been calibrated).
When the integrity of an instrument’s calibration has been compromised (usually due to exposure to a shock, vibration, or physical damage), it needs to be calibrated; failure to do this inevitably leads to inaccurate measurement; this is a very common measurement error.
        
             
        
        
        
- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in 
control and low in the entire ecosystem. They play an important role 
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to 
ecosystem. non-native to an ecosystem
 
        
             
        
        
        
All of the above, here's an explanation. The sun helps the water cycle due to evaporation which causes it to turn into a steam/gas. Now for wind, it's because the sun heats up the air and causes thermal energy which later turns into wind. And finally, weather, obviously the sun evaporates water which causes it to be rainy/drowsy.
        
                    
             
        
        
        
"They are <span>multicellular" is not a characteristic of bacteria. Although it should be noted that the smallest life forms don't necessarily have to be bacterial. </span>
