Question

Read the following excerpt about water availability to living organisms. “Water covers 75 percent of Earth. 97 percent of water on Earth is salt water. Only 3 percent of water is available as fresh water, but most of this water is locked up in solid glaciers and polar ice caps.” Based on this information, which is the best approximation of the amount of water on the planet that is available for animals to drink? 1 percent 3 percent 10 percent 75 percent

Answer 1

Answer: 1%

As per excerpts, Water covers 75 percent of Earth and  97 percent of water on Earth is salt water, meaning only 3 percent of water is available as fresh water. Based on this information, 3% of 75% of the water on earth is available as fresh water or 2.25%. Since most of the water is said to be locked up in solid glaciers and polar ice caps,  the amount of water on the planet that is available for animals to drink is lesser than 2.25% so the best approximation is 1 percent.

Answer 2

I had a test on it and it said it was 1 percent
