Question

The running water is called

• A. Lentic
• B. Lotic
• C. Mesic
• D. Xeric

Hint:

Lotic = "Flowing" (Think of a Locomotive moving).
Lentic = "Still" (Think of a Lake).
Lotic waters are usually cleaner and have more oxygen than lentic waters.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the specific limnological term used to describe freshwater ecosystems that consist of flowing or running water.
Detailed Explanation:

• Lotic Ecosystems:
From the Latin lotus, meaning "washed" or "flowing."
Lotic ecosystems include rivers, streams, brooks, and springs where the water moves in a directional path.
Characteristics include high dissolved oxygen (due to constant aeration) and specific adaptations of organisms to withstand the current.

• Lentic Ecosystems:
From the Latin lentus, meaning "slow" or "still."
Lentic ecosystems include lakes, ponds, swamps, and marshes where the water is relatively still or standing.

• Analyzing Other Options:
Mesic: Refers to a habitat with a moderate or well-balanced supply of moisture (not too wet, not too dry).
Xeric: Refers to an extremely dry habitat (like a desert).

Step 2: Final Answer:
Running or flowing water systems are technically termed Lotic ecosystems.
