A group of scientists studied some trees in a pine forest. In the densely forested areas, the trees were within 1 m of each other. The scientists observed that these trees had dead branches near the ground. They measured the height above the ground at which the first living branches were found on different-sized trees in the forest. Then they repeated this procedure on the same kind of trees in an open meadow. This graph summarizes the scientists’ data.

Which inference is best supported by these data?

A) Pine trees in a dense forest can grow taller than pine trees in an open meadow.
Eliminate

B) Pine trees in a dense forest compete for sunlight with the surrounding trees.

C) Pine trees in a dense forest are part of a less-complex food web than pine trees in an open meadow.

D) Pine trees in a dense forest have more living branches than pine trees in an open meadow.

In an open meadow, none of the trees will be sheltering the other trees from resources such as sunlight. The trees will located close to each other to block sunlight. Hence, we will see that in an open meadow all trees will have ideal tall height.

On the other hand, in a dense forest, trees will be located near to each other and tall trees will block the sunlight from the lower trees. As a result, trees with different lengths will be seen. The trees will maintain their height according to the sunlight which reaches them.

Answer:

The correct option is B) Pine trees in a dense forest compete for sunlight with the surrounding trees.

Explanation:

In an open meadow, none of the trees will be sheltering the other trees from resources such as sunlight. The trees will located close to each other to block sunlight. Hence, we will see that in an open meadow all trees will have ideal tall height.

On the other hand, in a dense forest, trees will be located near to each other and tall trees will block the sunlight from the lower trees. As a result, trees with different lengths will be seen. The trees will maintain their height according to the sunlight which reaches them.
