Plants are important to us. All the food that we
eat comes either directly or indirectly from
plants. However, the question is, what do plants
eat ? Well, they do not actually eat the way we
do but they make their own food. The process by
which this takes place is called photosynthesis.
Plants make food in their leaves. The leaves
contain a pigment called chlorophyll which gives
the leaves their green color. Besides
chlorophyll, plants also need the light from the
sun to help in its food production. Besides the
sun, plants can also make food with the use of
other light sources such as a light bulb. For
photosynthesis to take place, plants also need
carbon dioxide that is found in the air. Animals
and people help in providing carbon dioxide for
the plants to make food when they breathe out.
lastly, but just as important, plants make
use of their roots to absorb the nutrients found
in the soil to help them make food. When all
these different things are present, the plants
can then make food. In the process of making
food, plants release oxygen, which is beneficial
to animals and people. Plants, animals and
people are dependent on one another to survive,
Plants provide oxygen for animals and people to
breathe and animals and people provide carbon
dioxide for the plants to make food. |
