What are the four main layers of a forest, from bottom to top?

• Subfloor, Floor, Understory, Canopy

• Roots, Ground, Shrubs, Treetops

• Soil, Grass, Bushes, Leaves

• Basement, Ground floor, Middle floor, Top floor

How can you determine the age of a tree?

• By measuring its height.

• By counting the number of rings in its trunk.

• By observing the color of its leaves.

• By checking the softness of its bark.

What is the primary role of decomposers in a forest ecosystem?

• To provide shade for smaller plants.

• To break down dead organic matter into soil.

• To produce oxygen for other organisms.

• To help trees grow taller.

What is a notable characteristic of redwood trees?

• They are typically 50 meters tall

• They are found only in tropical climates

• They can be over 100 meters high

• They are usually less than 100 years old

What is a primary material that humans obtain from forests?

• Minerals

• Wood

• Water

• Fossil fuels

Which of the following is NOT identified as a distinct level within a forest?

• Canopy

• Understory

• Mid-level

• Forest floor

What is a primary reason trees do not grow above the timberline?

• The soil is too fertile, leading to overgrowth.

• The air is too dense, preventing proper respiration.

• The summers are too short and winters are too long.

• There is an excess of moisture, causing root rot.

Why is the forest canopy referred to as "the last biotic frontier"?

• It is the highest point in the forest, making it difficult to access.

• It contains unique species found nowhere else in the forest.

• It has been studied for a much shorter period compared to other forest layers.

• It is the most dangerous part of the forest due to strong winds.
