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

The right answers are : Radiant energy and Conservation 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.

 Radiant Energy and Conservation of Energy.

i believe your answer would be c.. : )

correct answer: false

while planning water activities, it is very important to consider the weather, because if we do not plan and are going for a surf, then it might be that the hurricane came and drown us or may carry us to long distance from where we can not come back. there are many reasons to take information about the weather when we are planning any water activities.

hence, the correct answer would be false.
