Two example of a nonliving thing responding to

Two characteristics of life that
could be applied to nonliving things are response to environment and energy
processing. Fire is a good example of a nonliving thing responding to the
environment. Wind, rain, and landscape affect a fires ability to self sustain.
And fire requires fuel or energy processing from oxygen levels and a source for
it to burn like trees, grass, etc. My conclusion is that there are several
different nonliving things that fit the characteristics of life but, will not
meet all the criteria. This is what separates biotic from abiotic. I look
forward to studying the characteristics order and evolution of life the most of
the nine. It is extremely relevant to my professional life in that I plan to
work with wetland conservation and preservation. It is important to understand
how living and nonliving things interact and impact each other in the
environment. Nonliving things impact the livelihood and success of all
different kinds of species and are just as important in habitats as actual life.

The three individuals I asked why a
dog is alive and a donut is not all gave me similar answers. This did not
surprise me as I work with biologists and all the members in my family are all
in the science field. One said that a dog has internal system functions and
organs (cells) keeping it alive while the donut does not. Another answer I
received was being alive requires movement, internal organization, homeostasis,
energy use, reproduction, and growth and development. The last person I asked
stated that a dog is self aware, can express various emotion and intellect, and
depends upon food, water, sex, and sleep. From this experiment, I learned that
there are intricate criteria for the classification of something to be
considered alive and these criteria are always changing and being expanded

The discovery of pandoraviruses
tells us that there may be a need to add a fourth domain of life. In the
article, the studies suggest that 93% of the 2,500 genes in the makeup of
pandoraviruses cannot be traced back to any known lineage found in nature. That
alone may be cause for adding viruses to the phylogenic tree. The discovery of
these viruses indicates how little we still know about life on Earth (Dell’Amore,
