Question

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 .

Answer 1

The scientific law of one organism feeding off to other where energy is transferred from one form to another is known as the law of conservation of energy.

Explanation-

Energy from the the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.

The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.  

Answer 2

Answer:

Law of conservation of energy

Explanation:

As per the law of conservation of energy 'Energy in a system can neither created nor destroyed but it can be transformed from its one form to another'. In the given question, energy is coming from the sun which is primary and biggest source of energy. So energy of get transformed by the process of photosynthesis to the food of trees in the ecosystem. Then from primary food chain to successive food chains in the ecosystem by ten percent rule( only 10% energy  passes from one level to another in the food chain).
