There are a few different organisms that could potentially contain genes encoding enzymes that can fix carbon from 
. However, one of the most likely candidates would be plants. Plants have a unique ability to convert into useful organic compounds, and they typically have a large number of genes encoding enzymes involved in this process. Therefore, it is reasonable to believe that plants may also have genes encoding enzymes that can specifically fix carbon from .
<h3>
How do plants convert into useful organic compounds?</h3>
Plants are able to convert into useful organic compounds through the process of photosynthesis. This process occurs in the chloroplasts, which are organelles found in the plant cells. In photosynthesis, the plant uses sunlight to convert and water into glucose and oxygen. The glucose can then be used by the plant for energy, while the oxygen is released into the atmosphere.

The main function of environmental policy is to <u>reduce human impact on the environment (B).
</u>

<h3>Further explanation
</h3>
Humans impact the environment in so many ways such as overpopulation, overfishing, pollution, and deforestation. This condition leads to many other problems: poor air and water quality, climate change, and soil erosion. Increasing population means increasing demand for consumption that may destroy the natural resources and environment.
The government or an organization creates environmental policies to regulate environmental issues and to reduce human impact on the environment. According to McCormick environmental policy is “any action deliberately taken to manage human activities to prevent, reduce, or mitigate harmful effects on nature and natural resources, and ensuring that man-made changes to the environment do not have harmful effects on humans or the environment.”
The policy regulates the use of resources and to reduce pollution to promote human welfare and protect natural resources. Some example of environmental policy, governments forbade the use of hazardous substances in agriculture or apply maximum emission levels for the industry to ensure minimum environmental quality.

The formation of the canyon provides a physical barrier that me lead to speciation between the two populations if interbreeding is prevented. The population to the west of the canyon will probably adapt to feeding on the berries on land, and might therefore evolve traits for a terrestrial, vegetarian existence. The turtles to the east of the canyon will evolve to take advantage of the river environment, and aquatic characteristics will be further emphasised.
