Exploring Rainforest Layers

What are the four layers of the rainforest?

• forest floor

• understory

• forest edge

• canopy

• emergent layer

Where is the emergent layer located?

• The emergent layer is located at the top of a rainforest.

• The emergent layer is at the base of the rainforest.

• The emergent layer is located in the middle of the forest.

• The emergent layer is found underground.

What conditions are found in the emergent layer?

• Calm winds and shaded areas

• Frequent rainfall and dense fog

• Low humidity and cool temperatures

• High temperatures, strong winds, intense sunlight, and tall trees.

How tall can trees in the canopy grow?

• 30 to 60 meters (100 to 200 feet)

• 10 to 20 meters (30 to 65 feet)

• 15 to 25 meters (50 to 80 feet)

• 70 to 90 meters (230 to 295 feet)

What is the role of the canopy in the rainforest?

• The canopy is primarily made of rocks and minerals.

• The canopy blocks all sunlight from reaching the forest floor.

• The canopy serves as a barrier against all animal movement.

• The canopy provides habitat, regulates climate, and supports photosynthesis.

What types of plants are found in the understory?

• Shrubs, young trees, ferns, and herbaceous plants.

• Desert shrubs

• Aquatic plants

• Cacti and succulents

How high can the understory layer reach?

• 10 to 15 meters (33 to 49 feet)

• 6 to 10 meters (20 to 33 feet)

• 1 to 5 meters (3 to 16 feet)

• 0.5 to 1 meter (1.5 to 3 feet)

What is the composition of the forest floor?

• Only trees and shrubs

• Rocks and minerals

• Animal habitats and nests

• Decomposing organic matter, soil, fungi, and microorganisms.

What types of wildlife inhabit the forest floor?

• Birds of prey

• Aquatic fish species

• Insects, small mammals, reptiles, amphibians, and fungi.

• Large mammals like bears

What do animals in the forest floor primarily eat?

• small mammals

• tree bark

• decaying leaves, fungi, and small invertebrates

• berries and fruits
