Example: This bird, a Robin, is acquiring energy by eating a worm. It also possesses the other 6 characteristics of living things, like having DNA and reproducing.
Example: This tree used to make its own food, reproduce, maintain homeostasis, and use energy, but it no longer carries out any of those life processes.
Examples: Seeds, nuts, fruits, and veggies are all capable of growing new plants which will be alive, but right now the seeds are dormant. Some bears and other animals are also dormant during the winter when they don't do much and use very little energy. In the spring, they resume activities and have to start eating more calories again.
Examples: Shells, antlers, hair, and bones are all products of living things which were left behind after the death of the organism or when it was finished with them.
Example: An airplane uses energy, but does not possess all 8 characteristics of life, therefore it is non-living.
