A marine scientist is studying photosynthetic organisms, which use sunlight to produce their own food. She observes that they tend to populate shallower ocean depths. She concluded that photosynthetic organisms can only live in areas of low pressure why is this a invalid scientific conclusion

This an invalid scientific conclusion because the other variables were not accounted for.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
