Chapter 29: Q. 27 (page 827)

Explain why frogs are restricted to a moist environment.

Short Answer

Expert verified

A moist environment is required, as frog eggs lack a shell and dehydrate quickly in dry environments.

Step by step solution

01

Introduction

Frogs are amphibians that belong to the order Anura. Anurans are among the most diverse groups of vertebrates, with approximately 5,965 species that occur on all of the continents except Antarctica.

02

Explanation

Frog eggs are fertilized externally, and like other amphibians, frogs generally lay their eggs in moist environments. A moist environment is required as eggs lack a shell and thus dehydrate quickly in dry environments.
