When we think of islands, we often think of them as land masses surrounded by water. Ecologists have suggested a much broader definition of an island. Which of the following would NOT be viewed as an island by an ecologist?

Mountain top habitats
Urban parks
Caves
The Sahara desert

The Sahara desert.

Explanation: The option that does not qualify as an island is the Sahara desert, it does not have the basic characteristics of an island. Continents are also generally surrounded by water bodies but they don't fall within the category of an island as they are too large to be called an Island.
