How energy flows from the Sun to living organisms to promote life. The problems if there isn't enough caloric energy and the possible solutions

1. Block 5 – Lesson 1

2. What do you see in the picture?

4. Life on Earth flourishes thanks to the flow of energy that
comes from the Sun. This energy reaches the Earth as
electromagnetic waves and it is perceived as light.

6. This energy is used by plants and some other organisms
that perform photosynthesis to manufacture food for
themselves and for other living organisms.

8. People need the energy stored in food to use it in
different ways. An example is the energy released
as heat which allows the human body to keep its
temperature at around 37 degrees Celsius.

10. When people cannot
maintain their normal
body temperature, they
can have serious
problems or even die.
This situation is most
evident in winter when
children and older
people’s drop below 34
degrees Celsius.

12. Thanks to advances in
science and technology,
it has become possible to
help older people to not
lose body heat.
Controlled conditions,
like a calorie rich diet, the
use of heaters that keep
home temperatures
stable, and the use of
thermal clothing, all help
in this respect.
