Instructions for the Student:
Hello! This worksheet will help you learn about the amazing world of amphibians. Please read each task carefully. Write your answers in the spaces provided or complete the diagrams/tables. Use your textbook, notes, or other learning materials if needed. Try to do all tasks by yourself. Good luck!
1 Key Features and Definitions
Amphibians are a unique class of vertebrates. Based on your knowledge, answer the following questions clearly.
a) What does the word "amphibian" mean? Why is this name suitable for animals in this class?
b) List the three main groups (orders) of modern amphibians.
c) What is metamorphosis? Describe it briefly in the context of a frog's life cycle.
2 Habitat and Adaptation Table
Amphibians live a "double life". Complete the table below by describing how amphibians are adapted to live in two different environments.
| Environment | Adaptations of Amphibians (List at least two) |
|---|---|
| Life in Water (e.g., as a tadpole) | |
| Life on Land (e.g., as an adult frog) |
3 Body Systems and Functions
Match the body system of an amphibian with its correct description and primary function. Draw a line connecting the system to its description and function.
Body Systems: A) Respiratory System | B) Circulatory System | C) Skin
| Description & Function | Matching Letter (A, B, or C) |
|---|---|
| 1. In adults, includes lungs for breathing air, but gas exchange also occurs through this moist, permeable organ. | |
| 2. Has a three-chambered heart (two atria, one ventricle) which mixes oxygen-rich and oxygen-poor blood to some degree. | |
