Question

Explain the function of the thick bark found on deciduous trees. Which of the following changes in deciduous forests occurs in the winter?

1) trees regain their leaves.
2) trees block the flow of water and nutrients to their leaves.
3) the leaves of trees begin to lose their chlorophyll.
4) trees live off of stored nutrients.

Answer 1

The thick bark on deciduous trees protects the tree and helps it survive in winter. In winter, deciduous trees live off stored nutrients.

Step-by-step explanation:

The thick bark found on deciduous trees serves several functions. One of its main functions is to protect the tree from physical damage, such as animal grazing or extreme weather conditions. Additionally, the thick bark helps insulate the tree and regulates its temperature, preventing excessive water loss and frost damage in winter. Finally, the bark contains cork cells that can produce new tissue and heal any wounds or injuries the tree may sustain.

As for the changes that occur in deciduous forests in winter, the correct answer is 4) trees live off of stored nutrients. During the winter, when the tree loses its leaves, it relies on the stored nutrients in its trunk and roots to survive. These stored nutrients are used to support essential metabolic processes and prepare the tree for the growth of new leaves in the spring.
