Answer:
Climate change?
Explanation:
A massive extinction event that took place 200 million years ago may have been caused by climate change, new research suggests. The findings shed new light on the pace of mass extinction, and imply that relatively small changes in atmospheric carbon dioxide levels may be enough to trigger an extinction event.

34 ATP molecules are produced from one glucose molecule during the electron transport chain
Answer:
The trends go up in the presence of nutrients.
Explanation:
There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.
