Reproduction, Heredity, Variety in fitness of population, and variety in characters among the population are all four conditions for natural selection.
There are four major reservoirs, or stocks, of carbon on Earth: 1) in rocks (this includes fossil fuels), 2) dissolved in ocean water, 3) as plants, sticks, animals, and soil (which can be lumped together and called the land biosphere), and 4) as a climate-warming gas in the atmosphere.
Answer:
In terms of carbon and energy sources, all cyanobacteria are photosynthetic autotrophs.
Explanation:
Cyanobacteria are prokaryotic microorganisms, that is, they have cellular structure that corresponds to the cell of a bacterium. As for carbon absorption and energy acquisition, all cyanobacteria are autotrophic and photosynthesizing, presenting photosystems I and II but not organized in chloroplasts, such as plants. Due to the presence of these chlorophyll-rich pigments, phycocyanins and phycoerythrins, they have been called cyanophytic algae for many years.
