Places located near the equator receives more sunlight than those located near one of the poles. This has something to do with the angle and how the sun casts its light. The more that you are at the center, the more direct the sunlight is shining on you. As you go further from the center, the angle of sunlight bends, giving an uneven distribution of sunlight to areas far from the equator. This is why most countries that are located far from the equator experience snow. They receive less sunlight than those who are living in tropical countries.
Answer:
The correct option is D. Chemoautotroph uses CO2 for carbon and H2 for energy.
Explanation:
Autotrophs can be described as organisms that are capable of making their own food. There are two types of autotrophs: photoautotrophs which use energy from the sunlight to produce food and chemoautotrophs have the ability to make biological compounds from inorganic matter.
The chemoautotrophs are capable of taking carbon from inorganic sources and converting them into useful organic compounds. They are also capable of taking hydrogen atoms and use them for deriving energy. Hence, D is the correct answer.
You can say that the reason they need to do this is because it is polluting the water and killing the life within. This then effects farms because they sell fish. This will affect their income which means they can't buy the supplies they need to grow crops. Then supply and demand will go up but they won't have any which will affect the people.
Hope that helps XD
