Tropical Rainforests Flashcards
What is the average temperature range in tropical forests?
The average temperature range in tropical forests is typically between 20°C to 25°C (68°F to 77°F).
True or False: Tropical forests have distinct dry and wet seasons.
False: Tropical forests generally have a warm climate with high humidity and rainfall throughout the year.
What percentage of the world’s biodiversity is found in tropical forests?
Approximately 50% of the world’s biodiversity is found in tropical forests.
Fill in the blank: Tropical forests are characterized by high levels of __________.
precipitation
What is the primary reason for the high biodiversity in tropical forests?
The primary reason for high biodiversity in tropical forests is the stable climate and abundant resources.
What type of soil is commonly found in tropical forests?
Tropical forests typically have nutrient-poor, acidic soil known as oxisols.
Name one adaptation of tropical trees to compete for sunlight.
One adaptation is the development of tall trunks and broad leaves to maximize light capture.
True or False: Most plants in tropical forests have thick bark.
False: Most plants in tropical forests have smooth bark to help shed excess moisture.
What is a common adaptation of animals in tropical forests for camouflage?
Many animals have evolved coloration and patterns that blend with their surroundings.
Multiple choice: Which of the following adaptations is NOT typical of tropical forest plants? A) Epiphytes B) Succulents C) Lianas D) Buttress roots
B) Succulents
What role do vines (lianas) play in tropical forests?
Vines provide structural support for plants and help them reach sunlight in dense canopies.
Fill in the blank: The upper layer of a tropical forest is called the __________.
canopy
What is the significance of the understory layer in tropical forests?
The understory layer is important for housing diverse species and is crucial for the forest’s overall ecology.
True or False: Tropical forest animals are generally adapted to seasonal changes.
False: Tropical forest animals are adapted to a relatively stable climate with less seasonal variation.
What is one adaptation of tropical birds for feeding?
Many tropical birds have specialized beaks that allow them to access a variety of food sources, such as fruits and nectar.
What is the primary function of buttress roots in tropical trees?
Buttress roots provide stability to tall trees in shallow soil.
Multiple choice: Which of the following is a common feature of tropical forest fauna? A) Nocturnal behavior B) Hibernation C) Migration D) All of the above
A) Nocturnal behavior
What is the term for plants that grow on other plants without harming them?
Epiphytes
Fill in the blank: The rapid decomposition of organic matter in tropical forests contributes to __________ cycling.
nutrient
What type of climate characterizes tropical forests?
Tropical forests are characterized by a tropical rainforest climate, which is warm and humid with high rainfall.
True or False: Tropical forests cover about 10% of the Earth’s land surface.
True
What adaptation helps many tropical insects avoid predation?
Mimicry and camouflage are adaptations that help many tropical insects avoid predation.
What is the role of decomposers in tropical forest ecosystems?
Decomposers break down dead organic matter, recycling nutrients back into the soil.
Name one reason why tropical forests are considered important for global climate regulation.
Tropical forests absorb significant amounts of carbon dioxide, helping to mitigate climate change.
