Answer:
if ur asking why here it is Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories
As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
<h3>
What is Kepler's second law?</h3>
Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.
This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.
From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

Im pretty sure the answer is B
A plant, Reason why is because since a plant is a producer it’s able to use energy from the sun to produce its food from carbon dioxide and water,,,((Might not make much sense but a plant is an organism))
