Explanation:
In general, photosynthesis in cyanobacteria uses water as an electron donor and produces oxygen as a byproduct, though some may also use hydrogen sulfide a process which occurs among other photosynthetic bacteria such as the purple sulfur bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle.
The answers are; geographical isolation and temporal isolation.
In temporal isolation, because the different species have different mating seasons, so even though their habitats overlap, they do not interbreeding is rare. Geographical isolation also plays a role because the different species are found predominantly in different sites during breeding, some in the woodland, some in the lowlands and others in streams.
Ecology is how nature works and flows, without it everything would be messed up, such as food chains and how people would be ranked on natures list.
