Hello. This question is incomplete. The complete question is:
"Which of the following is not an organic cause of mechanical weathering? A. lichens B. plant roots C. prairie dogs D. burrowing snakes "
Weathering or weathering is a set of processes of a physical, chemical and biological nature that contributes to the formation of relief and climate in the world, since it interferes with the transformations of rocks and contributes to the formation of soil.
Mechanical weathering occurs through physical processes, with the fragmentation of rocks thus forming various types of sediment (eg sand). It is mainly influenced by temperature and pressure variation. Thus, the process of rock dilation favors its fragmentation. Despite being caused by physical processes, mechanical weathering has organic influences such as plant roots, prairie dogs, burrowing snakes.
physical changes in an organism in order to survive in a given environment
Pollination is the process by which animals, wind, and rain transfer pollen to the pistil of a flower.

The amount of carbon dioxide in the atmosphere is controlled by the carbon cycle.
Processes that remove carbon dioxide from the air:photosynthesis by plantsdissolving in the oceans.
Processes that return carbon dioxide from the air:respiration by plants, animals and microbescombustion ie burning wood and fossil fuels such as coal, oil and gasthermal decomposition of limestone, for example, in the manufacture of iron, steel and cement.Cellulose
All cells contain carbon, because they all contain proteins, fats and carbohydrates. For example, plant cell walls are made of cellulose, a carbohydrate.Decomposers
Decomposers, such as microbes and fungi, play an important role in the carbon cycle. They break down the remains of dead plants and animals and, in doing so, release carbon dioxide through respiration.
For thousands of years, the processes in the carbon cycle were constant, so the percentage of carbon dioxide in the atmosphere did not change. Over the past 200 years, the percentage of carbon dioxide in the atmosphere has increased steadily because humans are:burning more and more fossil fuels as energy sourcesburning large areas of forests to clear land, which means that there is less photosynthesis removing carbon dioxide from the air.
