The Sun is the primary source of energy for ecosystems. The Sun emits . When an organism obtains nutrients by feeding on other organisms in the ecosystem, energy is used and released. Energy changes form, but it isn’t destroyed as it transforms. This scientific law is called the law of

First Blank.
1. Chemical energy
2. Mechanical energy
3. Radiant energy

Second Blank.
1. Conservation of energy
2. Conservation of matter
3. Transformation of energy

Radiant energy, or radiative energy, is the only energy that can propagate in a vacuum, in the absence of matter. It is based on the principle of electromagnetic radiation, itself based on photon displacement. On a daily basis, radiant energy is very present; this is how the sun illuminates us.

-The energy of an isolated system can not be destroyed or created .

➥The energy is conserved, and can be transferred from one part of the system to another and / or change shape (heat, speed ...) .

➥Energy can also switch from one system to another.
