There are about 11,200,000 billion metric tons of O2 in the atmosphere. Based on an estimated photosynthesis rate of 600 billion

Nadusha1986 [10]

Answer:

$t=18666.7years$

Explanation:

Hello,

In this case, since the rate at which oxygen is produced via photosynthesis is:

$600 \frac{billion\ metric\ tons}{year}$

Since the desired amount is 11,200,000 billion metric tons, the required time is:

$t=\frac{11,200,000billion\ metric\ tons}{600 \frac{billion\ metric\ tons}{year}} \\\\t=18666.7years$

Best regards.
