D. radiant
Light energy isnt nuclear because nuclear means explosive we use light for lots of things and it doesnt explode! chemical the sun is light but it is too hot to reach it and study it so it cant be formed or made gravitational means gravity light doesnt make everything like you on the moon nor makes you feel like you have an elephant on your back radiant is hot and bright and one example is the sun it provides warmth and light so people can see.
hope this helps!
Ecosystem
Explanation:
The relationship between the living and non-living things forms an ecosystem.
The non- living things like water, air, soil and other are required by the living organisms for leading their life cycle.
The living things forms the integral part of the natural cycling process of water, air and soil.
Thus this can be said that both living and non-living things are interdependent on each other and forms an ecosystem.
For example, if plants do not get water they will not be able to produce food also the transpiration will not occur which is an important part of the water cycle.
It would be a loss in biodiversity , due to invasive species because the abandonment of pythons grew and they bred and had babies
The answer is B.
An ecosystem is community plus nonliving components in an area.
An ecosystem includes both biotic and abiotic factors of an area that organisms interact with. Examples of abiotic factors would be soil, water, sunlight etc.
