Answer:
D) energy from the sun, air, and water
Explanation:
Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.
For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+
. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.
Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.

Answer:
<em>The shape of a cell can easily be seen through a light microscope.</em>
Explanation:
A microscope can be defined as a device which is used to visualize things which are otherwise not visible to the naked eye. The shape of a cell can be seen even through a light microscope. For example, an animal cell can be seen to have a round shape under the light microscope, a plant cell will be seen rectangular under the light microscope.
Other microscopes such as the electron microscope can even show the organelles present inside the cell.
