Impact of Sunlight on Photosynthesis Rate

Medium Data Representation Understanding Graphs And Tables

A group of researchers investigated the relationship between the amount of sunlight a certain species of plant receives and its rate of photosynthesis. The table below summarizes their findings over a 5-day experiment:

Day	Sunlight (hours)	Photosynthesis Rate (mg O₂/hour)
1	2	5
2	4	10
3	6	15
4	8	18
5	10	20

Based on the data provided in the table, which of the following statements is supported by the results of the study?

Photosynthesis rate decreases as sunlight exposure increases.

The optimal amount of sunlight for maximum photosynthesis is 10 hours.

Photosynthesis rates remain constant regardless of sunlight exposure.

Increased lighting does not impact the photosynthesis rate significantly.
