The correct answer is A. Less than one light year.

A light year is the distance light travels in one year. We know that the sun's light takes approximately 8 minutes to reach the earth. 8 minutes is much less than a year, so the correct answer is A.

Hope this helps =)

Destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

<h3>What is ecosystem?</h3>

All species and the physical environment with which they interact make up an ecosystem.

Nutrient cycles and energy flows bind these biotic and abiotic components together.
Photosynthesis brings energy into the system, which is absorbed into plant tissue.

As it is already mentioned that, water of the wetlands was carry nutrients which in turn was taken up by plants and vegetation, and if it will destroyed near a bay then the vegetation of that place will destroy as they will not get proper nutrients, which in turn also affects the ecosystem.

Hence destroying the wetlands will reduce the bay's water quality and vegetation will not grow effectively near bay as a result of which ecosystem will also destroy.

The new fossil i.e, Fossil B (2,000 year old) contains more carbon-14 than the old fossil i.e, Fossil A (5,000 years old ) does.

<h3>What are Fossils ?</h3>

Fossils are the preserved left materials of ancient organisms in trace form.

Fossils are not just the remains of the organism But also the rocks.

Carbon 14 works to analyse the period organic remains that are between 100 years old (minimum) and about 50,000 years old, (maximum).

If it is new, than not enough time has passed for radioactive decay to produce and if it is older than that, the amount of radioactive decay has dropped so less amount which means that anything beyond 50,000 years old becomes gibberish and may lead to high or low (usually low) concentration.

Hence,the new fossil Fossil B (2,000 year old) contains more carbon-14 than the older Fossil A (5,000 years old ) does.
