Concept explainers
Which of the following biomes is correctly paired with the description of its climate?
- A. savanna–low temperature, precipitation uniform during the year
- B. tundra–long summers, mild winters
- C. temperate broad leaf forest–relatively short growing season, mild winters
- D. tropical forests–nearly constant day length and temperature

Introduction:
A community of animals and plants with common characteristics for their environment is called a biome. It includes the likes of tropical forests, savannas, tundra and so on.
Answer to Problem 1TYU
Correct answer:
The tropical forests are near the equator, so their temperature is constantly warm and the day lengths are constant too. Therefore, option (D) is correct.
Explanation of Solution
Reason for the correct statement:
The region near the equator is always warm and the day length constant throughout the year as the sun moves almost perpendicular to the horizon all along the year.
Option (D) is given as “tropical forests-nearly constant day length and temperature”.
“Tropical forests-nearly constant day length and temperature is the biome which is correctly paired with the description of its climate”, it is the right answer.
Hence, option (D) is correct.
Reasons for the incorrect statements:
Option (A) is given as “savanna-low temperature, precipitation uniform during the year”.
Savannas are a mix of woodland and grassland ecosystems. They don’t have low temperatures and neither do they have uniform rain during the year. So, it is a wrong answer.
Option (B) is given as “tundra-long summers, mild winters”.
Tundra regions are very cold throughout the year and don’t have long summers. So, it is a wrong answer.
Option (C) is given as “temperate broadleaf forest-relatively short growing season, mild winters”.
Temperate broadleaf forests have cold winters. So, it is a wrong answer.
Hence, options (A), (B) and (C) are incorrect.
Tropical forests have constant temperature and day length throughout the year as they are near the equator.
