WebAug 14, 2024 · On the bark or rocks, crustose lichens are generally the first to settle, followed by folose and fruticose lichens. On block tops, it is not uncommon to see that bryophytes and vascular plants then settle – depending on ecological conditions (Figure 9). Soil lichens cannot be maintained in sites where the upper vegetation is too dense. WebAutotrophic organisms that convert solar energy into chemical energy are called phototrophs, and they appeared within one billion years of the formation of Earth. Then, cyanobacteria, also known as blue-green algae, evolved from these simple phototrophs one billion years later.
