Answer: a slime mold.
Step-by-step explanation:
A slime mold is a Eukaryotic organism that can live freely as a single cell organism, but can also come together to form a multicell organism. When there is a lot of food, they choose to stay as a single cell organism. When food is short, they may come together in different forms and are able to detect food better. They feed on microorganisms that live on dead plant material. It is most common to find slime mold in nature. You can find them on soil, lawns, forest floors, and even some fruit.
