Plants take energy
from the sun
and make food, which for plants is

Explanation:

Plants (plus some bacteria and algae) are autotrophs and undergo a process called photosynthesis.

They obtain light energy from the sun and capture it using a green pigment called chlorophyll, water from the soil is drawn up through the roots with capillary action, and carbon dioxide diffuses into stoma on leaves.

Then, in the chloroplast, these substances are turned into oxygen and glucose. Both of these are used in cellular respiration, which creates energy for the plant to grow and carry out cellular and biological functions. Therefore, glucose is often called "food" for the plant.

i'd say that the moon rock is about 2.2 billion years old.
