ECO 8.01 Understanding Ecosystems

CHALLENGE!
Fire — living or non-living?
A fellow scientist wishes to publish an article that says fire is a living thing. Here is his argument.
“Fire can be observed to move and grows in size. It consumes energy and requires oxygen. One fire can reproduce more fire. It is concluded that fire is living.”
WRITE a note to the scientist that explains why his conclusion is incorrect. Use formal scientific language.
CHALLENGE!
Viruses — living or non-living?
Consider the following facts about viruses:
viruses are non-cellular; they are not made up of cells
viruses form crystals
viruses can reproduce only if they invade plant,
animal, fungal or bacterial cells
antibiotics have no effect on viruses even though they kill bacteria.
Do you consider viruses to be living or non-living. Why?
