Answer:
Plants provide animals with habitat and produce oxygen, which the animals use to survive. Animals decompose and become natural fertilizer plants until they pass. Animals provide fertilizer, pollinate plants, and disperse seeds. Plants are also beneficial for animal homes since many species live in close proximity to plants.
Explanation:
I believe the answer is A because this is the two loop system because the air you take in from your lungs automatically is polluted. In the two loop system, the carbon dioxide is taken out out of the oxygen and is pumped back to the heart to be taken out of the body. The oxygenated blood is pumped into places it is needed.
The experimental procedure to test whether plants that are exposed to music grow faster than those that are not should follow the following steps. First, the plants must all be placed in a place where all must be exposed in the same type of environment in terms of sunlight, temperature, water and soil. Second, one of the plant must be exposed to two to three hours of classical music per day. Then you should expose one plant to five to six hours of music per day too. The remaining two plants will be treated as your control plants wherein these will be not exposed to music at all. Before you begin the experiment, you should take pictures of each plant. Next, you should take pictures after two, four and eight weeks. After the steps, observe any visible and palpable differences between the plants which were exposed to music and those that have note. Lastly, also observe the differences between the plants which were exposed to less and those exposed to more music.
