Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?(1 point) Responses by observing cellular respiration by studying biomagnification by observing cellular respiration by studying biomagnification by observing cellular respiration under bright light conditions by observing cellular respiration under bright light conditions by observing cellular respiration under the absence of light by observing cellular respiration under the absence of light by observing cellular respiration only when photosynthesis occurs
