Answer:
light
Explanation:
The above experiment is an investigation on the factors that affect photosynthesis which include carbon dioxide concentration,light intensity and quality,chlorophyll, water and temperature.Light was the independent variable. When the lant is moved to an area where light intensity is low, the rate of photosynthesis decreases.
After the experiment, oxygen gas is produced being a by-product of photosynthesis. Plants that are not adapted to an aquatic environment are not suitable for this experiment. The amount of carbon dioxide dissolved in water is low.
Answer: false, for example, if a frog eats flies, and the flies are land animals, if they go extinct the frogs could die off, meaning any fish or water dwellers that eat the frogs can starve and cause a large chain reaction.
