fire ecology: a study of forest fires
organic matter: material, e.g., plant leaves or animal waste, that was recently part of a living thing
organism: individual living thing that can react to stimuli, reproduce, and grow
perennial: a plant that lives for more than two growing seasons

based on information in the glossary, what is a precise and appropriate definition of microorganisms as it is used in the first section, \fire ecology: a study of forest fires\?

a. organic materials that can be seen with a special instrument
b. living things that can only be viewed through a microscope
c. plant material that is so small it cannot burn
d. a microscopic section of a single plant species

Explanation:

Analyze the glossary entries

The glossary provides definitions for terms related to the text. We can see:

• organic matter: material, e.g., plant leaves or animal waste, that was recently part of a living thing.
• organism: individual living thing that can react to stimuli, reproduce, and grow.
• perennial: a plant that lives for more than two growing seasons.

Additionally, there is a partially obscured entry at the top of the glossary list starting with "micro..." which corresponds to the target word "microorganisms".

Synthesize the definition

To define "microorganisms" using the glossary's style and terms:

• The prefix "micro-" means extremely small, typically requiring a microscope to be seen.
• The root word "organism" is defined in the glossary as an "individual living thing".
• Combining these two concepts, a microorganism is an extremely small living thing (organism) that can only be viewed through a microscope.

Evaluate the given options

• A. organic materials that can be seen with a special instrument: This refers to "materials" (organic matter) rather than living "organisms".
• B. living things that can only be viewed through a microscope: This correctly combines "organism" (living thing) with "micro-" (microscopic scale).
• C. plant material that is so small it cannot burn: This is factually incorrect and does not define a microorganism.
• D. a microscopic section of a single plant species: This describes a specimen slide rather than an independent living organism.

Therefore, Option B is the most precise and appropriate definition.

Answer:

• (A) organic materials that can be seen with a special instrument
• (B) living things that can only be viewed through a microscope (Correct answer)
• (C) plant material that is so small it cannot burn
• (D) a microscopic section of a single plant species
