Botany Question 18 – AP-EAMCET 2025

← Back
One acre of trees annually consumes the amount of carbon dioxide equivalent to that produced by driving a car for 26000 miles. The same acre of trees also produce enough oxygen for how many people to breath for a year.

Trees play a crucial role in maintaining atmospheric oxygen levels through photosynthesis, which is vital for life on Earth.

Step 1: Understand the Question✦ Active

The question asks for the number of people that one acre of trees can provide enough oxygen for in a year. It also provides context about carbon dioxide consumption, but this information is not directly needed to answer the oxygen production part of the question.

💡 Teacher's Secret Hint

Focus on the specific question being asked. Sometimes, extra information is provided as a distractor or for context, but not all details are necessary for the calculation.

Step 2: Recall Environmental Facts○ Expand

This question relies on general knowledge about the environmental benefits of trees, specifically their oxygen production capacity. Environmental studies often cite statistics regarding the amount of oxygen produced by a given area of forest.

💡 Teacher's Secret Hint

Environmental science questions often test knowledge of common ecological facts and figures. It's useful to remember key statistics related to carbon sequestration, oxygen production, and water purification by natural ecosystems.

Step 3: Determine the Answer○ Expand

According to various environmental studies and common ecological facts, one acre of trees produces enough oxygen to support approximately 18 people for one year. This figure accounts for the average oxygen consumption of humans and the average oxygen output of a healthy acre of forest.

💡 Teacher's Secret Hint

While the exact number can vary based on tree species, age, and density, '18 people per acre per year' is a widely accepted average for educational and general knowledge purposes.
