Solution:
Nitrogen is important because, it helps us grow crops, and it produces grass for animal. It comes from lightning and is named nitrogen fixation
By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer). In nature, this process is carried out by certain bacteria (present in the root nodules of legumes such as beans and peas), blue-green algae, and the lightning flash.
Thus the Nitrogen form the atmosphere the biotic part to the ecosystem converted into the biotic part.
The dependent variable being measured in the preceding plant experiment, “How Plants Grow In Response to Light,” is the plant's growth. The independent variable is how the plant grows in response to variations in the amount of light it receives.

What is florist hypothesis?</h3>
The independent variable is how the plant grows in response to variations in the amount of light it receives.
Determine the variable that will be altered first. In this instance, the plant's exposure to light is altered. The independent variable is this.
A clear, explicit, testable assertion regarding the expected relationship between variables or the explanation for an event is called a research hypothesis (or scientific hypothesis).
Therefore, plant growth, hormone concentration, shoot and root, floral pattern development are the part of data in the hypotheses.

A volcanic winter is a reduction in global temperatures caused by volcanic ash and droplets of sulfuric acid and water obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, particularly explosive volcanic eruption.
