Explanation:

🆕 New Concept Discovered: Species Distribution and Ranges
How species are spread across geographic areas.

Step 1: Analyze the definition of native range (Option a)

A species' native range is the geographic area where that species has historically lived and thrived without human intervention. Areas where a species was introduced by humans are considered introduced or non-native ranges. Therefore, statement a is true.

Step 2: Analyze seasonal and breeding ranges (Options b and c)

Many migratory species (like certain birds, whales, or insects) travel to specific geographic regions only during certain times of the year.

• A breeding range is where they go specifically to mate and raise young (making statement b true).
• A seasonal range refers to areas inhabited during specific seasons, such as wintering grounds (making statement c true).

Step 3: Analyze ecosystem distribution patterns (Option d)

An ecosystem contains many different species (plants, animals, fungi, bacteria). These organisms have different resource requirements, behaviors, and tolerances. Consequently, they do not all share the same distribution patterns; some may be clumped, some random, and others uniform. Therefore, statement d is false.

Answer:

D
