WebA timeline for early Earth Mainstream science currently believes that the Earth was formed about 4.54 billion years ago (Ga), and the oceans first formed about 4.4 Ga. The first age of Earth is called the Hadean, and it predates most of the surviving rocks today. WebIn primitive days, cyanobacteria were only the primary producers because the redox structure of oceans favoured them to fix nitrogen and also they had the capacity to use water as the source of electrons in photosynthesis. They made the atmosphere oxygen rich and allowed the appearance of aerobic organisms. Thus, the correct answer is option C.
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. Cyanobacteria (Figure 3) began the oxygenation of the atmosphere. WebMay 1, 2004 · Introduction. The photosynthetic eukaryotes (i.e., algae and plants) define a vast assemblage of autotrophs (Graham and Wilcox 2000).The emergence dates of these taxa have proven difficult to establish solely on the basis of fossil or biomarker evidence ().Recent phylogenetic data suggest that the different algal groups diverged near the …
