I believe the answer is Elongation.
Hope this helps! :)

Answer:
1. Food / nutrients
2. Autotrophs
Explanation:
The word "autotroph" means "automatic nourishment", a word of greek origin. Autotrophic organisms are a group of organisms that don't need to find / hunt their food, since they can make it using the radiation (energy) provided from the sun along with other elements.

It is believed that a less massive star will age more slowly than a more massive star, despite the fact that massive stars have much more fuel. The reason that a more massive star will burn out quicker is because it takes a significant more amount of energy to keep the star burning due to the increased diameter of the star compared to the less massive star. A less massive star will use its fuel less quickly due to being smaller and having less mass to fuel.
The massive star burns its fuel at a greater rate than the less massive star.
A large cloud of gas (hydrogen) and dust a nebula begins to collapse
The collapsing cloud begins to spin
The spinning collapsing cloud flattens into a rotating disk
Material in the disk begins to accumulate in the center
As the material coalesces in center, it becomes dense, compresses, and heats up.
More and more material coalesces to form a protostar.
The protostar continuse to accomulate material from the surronding disk and grow.
Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of nuclear fusion to begin.
Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.
Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.
Then the young star stops accumulating material.
