Exploring Plant and Animal Adaptations in Tropical Rainforests

The video discusses the environmental stresses in tropical rainforests, such as heavy rainfall, competition for sunlight, and nutrient-rich but shallow soil. It explains how plants adapt with water-repellent leaves, tall trunks, and shallow roots. Animals adapt by living in trees, and decomposers play a crucial role in maintaining soil fertility.

What are some of the environmental stresses faced by tropical rainforest ecosystems?

• Low temperatures and nutrient-poor soil

• High winds and sandy soil

• High temperatures and low rainfall

• High rainfall and competition for sunlight

Why is the soil in tropical rainforests considered nutrient-rich but shallow?

• Because of the high amount of decomposers

• Due to the presence of deep-rooted plants

• Because of frequent fires

• Due to the lack of plant diversity

How do the leaves of plants in tropical rainforests adapt to high rainfall?

• They become thicker to store water

• They change color to reflect sunlight

• They are designed to repel water

• They grow larger to absorb more water

What is a common characteristic of tree trunks in tropical rainforests?

• They are short and wide

• They grow very tall and straight

• They have deep roots

• They are covered in thorns

Where do many animals in tropical rainforests live?

• In the trees

• In the water

• On the forest floor

• In underground burrows

What role do decomposers play in tropical rainforests?

• They reduce the amount of rainfall

• They make the top level of the soil nutrient-rich

• They help plants grow taller

• They compete with animals for food
