Nookie1986 [14]

Answer: Nitrogen-fixing Bacteria

Explanation:

In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.

Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

Think about a natural resource that everyone in your community uses, such as the air in Earth's atmosphere or drinking water. Wh
Greeley [361]

Answer:

Explanation:

The rights of the resource depends on the resource in question. For example, an abundant resource such as Air would be considered a birthright, and no one can actually hold the rights to it, also since it cannot be taken. On the other hand, limited resources such as water would fall under the rights of the landowner. Therefore, any and all land property rights in the country would apply to the body of water, limited to the boundaries of the land. Meaning that if a stream or body of water passes the individual's land it is also within the rights of the owner of the other piece of land in which the water passes through.
