Answer:
Experiment
Explanation:
For such an investigation an Experiment would be the better option. This is because in an experiment you would have both an experimental group and a control group. This would allow you to use fertilizer on one but not the other, therefore, providing seperate results that you can use to compare with one another. This ultimately helps you determine the actual effects that fertilizer has on the growth of plants, since the fertilizer would be the only variable in the experiment. An observational study would only allow you to observe the plants in a natural scenario, without interfering and seperating the plants into different groups with different environments.
Answer:
Nitrgen Cycle
Explanation:
Animal waste includes nitrogen that passes through the nitrogen cycle, these steps summarise into:
The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms.
Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb.
Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere.
The stem is most likely made up of vascular tissues. The main vessels present on vascular tissue are the xylem and phloem. These two tissues work as pipes for the transport of water and nutrients inside the stem. Xylem transports water and some nutrients from the roots. The Phloem <span>transports the soluble organic compounds that were produced during </span>photosynthesis from the leaves, and in the case of the cactus photosynthesis happens on the actual stem,<span> to the rest of the plant.</span>
