Cell is highly concentrated compared to blood
Let's play devil's advocate just for fun. ;-)
1) neither of them are a concern. Even if humans overpopulate the earth, the strong will find a way to survive and Darwin's theory of evolution will determine who deserves to pass on their genes and rule the world. This will result in stronger and stronger humans each generation. Economic wealth is not a concern for similar reasons. The strongest, smartest humans will pass on their genes and their wealth, thus ensuring that only strong, smart humans will survive.
2) People who own the land should decide what to do with it. If there is a disagreement, they can fight about it, and call all their relatives to come back them up in a fight. Whoever survives the fight gets to make the rules.
3)Sustainable develpment strategies are not necessary, becauase God has a plan. We can continue to burn oil, deplete the ozone, and drive giant SUVs because God will provide for us, and then eventually he will take those to heaven who deserve it and let the rest wallow in their hellish filth. >:-)
This is a fun question. Since it's an opinion, it can't be wrong, right? LOL
Answer:
ecosystem ecology
Explanation:
The ecosystem is the basic unit for supporting life, but an ecosystem goes beyond organisms living in one place. Life depends on the recycling of resources between organisms and the environment in which they live, between organic and inorganic forms. Ecosystem ecology studies these transformations and integrates into both terrestrial and aquatic ecosystems, attracting fields as diverse as atmospheric chemistry, hydrology, soil science, physiology, and ecology.
For this reason, The study of nutrient cycling through the environment is an example of subjects that are studied in ecosystem ecology.
The correct answers are B. and C.
