The biodiversity is ______ at lower altitudes and ______ with increasing higher latitudes.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Highest, Decreases
Biodiversity is not uniform over the earth. It is highest in the warm, stable tropics near the equator and in the lowlands, and it falls as one moves to higher latitudes, towards the poles.
Option (1) Highest, Decreases — Correct. Low places near the equator have the most species, and the number decreases towards the poles. Colombia, near the equator, has nearly 1,400 bird species; Greenland, at 71° N, has only 56.
