Chapter 18, Problem 6FIB
Summary Introduction
Introduction:
In moist soils at the water edge, few small green algae began to grow taking advantage of available nutrients and sunlight. These algae did not have huge bodies to support the force of gravity and in the thin film of water on soil allowed them to obtain water easily. Nearly 475 million years ago, some of these algae gave rise to “multicellular land plants”. After land plants evolved, providing the potential source of food for other animals, animals emerged from the water (sea, ocean and so on).
