Answer:
A. the concept of cultural landscape
Explanation:
The adobe is a structure that was made by three tribes (Zuni, Pueblo, and Hopi) that lived in Southwest of America. The adobe is built with sun-dried earth made from sand to make strong brick-like materials, clay, water, sandstone mixture, and organic matter. Gaps were filled with much more mud between the blocks to prevent the wind, rain, and keep out bugs and other unwanted pests. The Adobe building is an example of a cultural landscape.
The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
