Astudent drew the following model.
carbon dioxide + > sugar + oxygen
what does the model represent?

a. how plants transform light into stored chemical energy
b. how energy is released from sugar molecules
c. how the sun delivers thermal energy to earth
d. how bacteria transform nitrogen into a usable from

The correct answer is-

A. How plants transform light into stored chemical energy.

The given equation in the model of the represents word equation for photosynthesis.

Photosynthesis is a process of formation of food ( that is a carboydrate)  in green plants and algae using CO2 (carbon dioxide) and H2O (water) in the presence of sunlight.

During this process, a green pigment in the chloroplast called chlorophyll, absorbs solar energy and converts it into chemical energy in the form of ATP and NADPH.

In the next phase, which is a light independent phase ,the chemical energy is utilized in the formation of glucose, which is a food molecule for green plants and algae.

Thus, option A) is the right answer.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
