The sun is the primary source of energy for ecosystems. the sun . 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 .

These are the answers, I just got a 100 on the test.

1. The Sun emits radiant energy

2. This scientific law is called the law of conservation of energy

(PLATO ANSWERS)

Radiant energy; Law of conservation of energy  

Explanation:  

The radiant energy is the type of energy which is released by the sun. It the ultimate source of energy on the earth.

The energy from the sun is trapped by the plant and it is converted from the radiant energy into chemical energy .

A part of this energy is transferred to animals and some part is released in the environment in the form of heat energy.

Then this transformation of energy  is known as conservation of energy because energy is not lost it is just converted from one form to another form.
