Will mark as brainliest
expeople1 [14]

The answer is C

because plants use light energy from the sun to make their own food providing energy. The food created is a type of sugar.

This would make it definitely not A or D. The only answers left would be B and C but, technically the sunlight doesn't deliver the sugar straight to the plant so I'd go with C.

Hope that his helped!

What do you think explains why the larger elements are able to form in a supernova explosion? Use evidence from the Supernova 10
lubasha [3.4K]

Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.

<h3>What is Supernova?</h3>

This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.

The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.

This is therefore the reason why it was chosen as the most appropriate choice.
