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.
Intensifying requirement with developing intensity of the sea is the vastest impediment to a seaside examination. Prolonged force at the unrivaled intensity in the mare would compress articles strong satisfactorily to let an individual lose consciousness. The heightened tension further presses the lungs such that a person is incompetent to recuperate. The immense strength would additionally meddle with the conventional physiological means and guide to perishment.
D) punctuated equilibrium.
punctuated equilibrium The steady, stable state is punctuated by rapid change, thus the phrase punctuated equilibrium.
