ASAP When attempting to determine where plants get their food, how did soil measurements affect the experiments? A. Reduction in
soil mass proved that plants get their food from the soil. B. The soil mass did not change, proving that plants do not get their food from soil. C. Increase in soil mass proved that plants do not get their food from the soil. D. Soil measurements were not involved.
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
<u>Competition</u> describes an interaction in which two organisms that interact must use the same limited resources because they are competing for them.
A decrease in dissolved oxygen. This is because oxygen is a byproduct of photosynthesis. If the plants are in water, some of the oxygen they produce will become dissolved in it. Without those plants, you have less dissolved oxygen.
