Question 1 - 30
What is more significant in determining the characteristics of a biome Latitude (horizontal lines) or Longitude (vertical lines)?
![Page 8: Unit Two: Ecology The study of our fragile home](https://reader035.fdocuments.in/reader035/viewer/2022062410/568164bc550346895dd6ca73/html5/thumbnails/8.jpg)
Answer 1 – 30
Latitude has a greater effect on the amount of sunlight that will reach any spot on Earth. So, changing the latitude of a location can greatly effect any climate. So, as we change latitude from pole to pole we see large changes in ecosystems.
