<span>Answer: 1%</span>
<span>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.</span>
Answer:
1100
Explanation:
There is 10% of total energy in each increasing trophic level. 10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.
1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.
1,000 + 100 units of combined energy would be 1,100 units of energy.
