Chapter 21, Problem 10A

Summary Introduction

To arrange:

The adaptations of life on land from most important to least.

Introduction:

The adaptation is the response of the organism to a long-term change in the environment. Through different adaptations, organisms make themselves suitable for surviving in the new environmental conditions and pass them to the next generations.

Explanation of Solution

The conservation of water is the most important in the adaptation of life on land. The water on land is not enough to support the demands of water for the organism. The second priority will be the changes in the reproduction pattern, which is the evolution of pollen dispersal in the plant through different means other than water. The least important adaptation is the evolution of flowering plants and seed formation.
