Answer:
It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.
The three gases that are part of Earth’s cycles in both the atmosphere and biosphere are:
- oxygen
- - nitrogen
- - carbon dioxide
<h3>Explain your answer?</h3>
The oxygen, nitrogen, and carbon dioxide are the three gasses that are constantly moving through the atmosphere and biosphere in their own respective cycles.
The oxygen is used by the animals for breathing, but it is also released as a byproduct by the producers. The nitrogen is used as a food source for the producers, as well as the carbon dioxide which is crucial for the process of photosynthesis.
Thus, Part of them is released through decomposition, part by releasing them in the atmosphere or in the soil.
