Answer:

energy is of course required for photosynthesis to occur as photosynthesis is self is the process of plants of green plants to make food or to provide food for themselves in the presence of sunlight carbon dioxide and using water from the soil in the definition you can also say that sunlight is needed for photosynthesis to take place and some light is a form of energy which is solar energy so energy is required for photosynthesis to occur

Answer:

Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

When looking into a tall glass of ice tea, you observe the tea looks darker when looking down from top to bottom, than when look
liubo4ka [24]

Answer:

Difference of path length

Explanation:

When we look into glass of ice tea, from top to bottom path length will be more as compared to when we look from side of the glass.

According to Beer Lambert law, absorbance is proportional to the path length. Path length is the distance that light travels through the material.

More path length will lead to more absorbance of light and more the absorbance more the darker tea looks.

Moreover, tea is a homogeneous solution, therefore, concentration of will be same through out the solution. Since, concentration is same, therefore, the effect of gravity will be also be same on all particles.

Therefore, difference in path length is responsible .

So, the correct option is option a, difference in path length
