Question

(Select all that apply.) Why isn't fire considered alive even though it can move and grow?

Answer 1

Answer:

The correct answer will be option it lacks cells, lacks DNA and lacks the ability to maintain homeostasis.

Explanation:

Biologists have tried to remove confusion between living and non-living things by making a list of characters common to all living beings like cellular organization , metabolism , reproduction , homeostasis , growth and development, heredity, response to stimuli  and adaptation through evolution.

Since, fire shows few characteristics of living beings like growth, complexity and movement but it lacks the basic unit of life that is a cell, lacks genetic or heredity material-DNA which is passed to offsprings and also lacked the ability to maintain homeostasis ,therefore it cannot be considered alive.

Hence, it lacks cell, lacks DNA and lacks the ability to maintain homeostasis are the correct options.

Answer 2

Hmm.. This is confusing I know, but i believe the last time i saw a question like this it is the lack of a maintaining homeostasis. A fire can not do this on its own accord.
