Mario and several friends spend a day at the beach. While watching the ocean waves crashing to shore, Mario wonders how much of

the world's water is contained in different types of bodies of water such as oceans, lakes, and rivers. He decides to research the percentage of Earth's water found in different locations. Which does his research reveal? Multiple choice question. A) Less than 3 percent of Earth's water is freshwater containing no salt. B) The ice caps located at both poles contain 30 percent of Earth's water. C) Fifty percent of Earth's water is in oceans and the glaciers at the poles. D) Ninety percent of Earth's water is in lakes, rivers, and groundwater.

Answer:

A

Explanation:

The correct answer here would be that <u>less than 3 percent of Earth's water is freshwater containing no salt.</u>

<em>Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms. </em>

The correct option is A.

Which of the following is considered assimilation in the carbon cycle?
kicyunya [14]

<u>Answer:</u>   C. A plant absorbing carbon dioxide during photosynthesis

<em>A plant absorbing carbon dioxide during photosynthesis can be considered as assimilation in the carbon cycle. </em>

<u>Explanation:</u>

<em>The process of carbon fixation is called assimilation in carbon cycle. In the atmosphere carbon occurs in the form of carbon dioxide. </em>

By the process of carbon fixation this carbon dioxide is converted into carbon compounds and these act as source of energy in an ecosystem.

Photosynthesis is an example of carbon fixation process. Other processes like chemo-synthesis also fix carbon. <em>Majority of carbon fixation takes place in marine environments.  </em>

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration
IceJOKER [234]

Answer:

<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>

Explanation:

To answer this question, we need to know that  

  • gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
  • net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr
