While in your backyard you notice an odd lump on a rock. As you move closer to observe it, you see that it does not move. You try observing it for a few days, but no changes are apparent and you note that it was cloudy on those days. After vacationing with your family for a week, you notice that the lump on the rock has grown much bigger and now some lumps have also appeared on a nearby tree. A quick look at the weather reports for the last week tells you it has been sunny and warm during your absence. Is this object living or nonliving, and how can you tell? living; it seems to reproduce, grow, and obtain energy from the sun

nonliving; it doesn't move or obtain energy

nonliving; it isn't able to reproduce

living; it is made of cells
