Question

you buy the following products at a pet store:

• some aquarium decorations
• 1 gallon of saltwater
• a thermometer

which term best describes this type of items?

• biotic
• abiotic
• aerobic

Explanation:

To determine the term, we analyze each option:

• Biotic refers to living or once - living components. The items (aquarium decorations, saltwater, thermometer) are non - living.
• Abiotic refers to non - living components of an ecosystem or environment. Aquarium decorations (like rocks, plastic plants), saltwater (a non - living substance), and a thermometer (a non - living tool) all fall under non - living things.
• Aerobic relates to processes requiring oxygen (e.g., aerobic respiration) and is not relevant to classifying these items.

Answer:

B. abiotic
