Document Summary
The green algae compromise two major types of organisms: the green algae and the land plants. Green algae are important photosynthetic organisms in aquatic habitats- lakes, ponds, and other freshwater settings. Although green algae have traditionally been considered protists, it is logical to study them along with land plants for reasons: 2) they are the closest living relative to land plants and form a monophyletic group with them transition from aquatic to terrestrial life occurred when land plants evolved from green algae. An ecosystem consists of all organisms in a particular area, along with physical components of the environment such as the atmosphere, precipitation, surface water, sunlight, soil, and nutrients. Green algae and land plants provide ecosystem services because they enhance the life-supporting attributes of the atmosphere, surface water, soil, and other physical components of an ecosystem. Green plants alter the environment in ways that benefit many other organisms.
