Answer:
1- Malthus's principle of population is basically the law of supply and demand applied to the relationships between food production and population growth, which he makes clear time and again throughout the Essay. As the food supply increases, food becomes cheaper, and more children are brought into the world
2- Environmental limits can be defined as the point beyond which the environment exceeds its ability to provide essential resources. For example, the steadily increasing world population presents a growing demand for goods, services, living space and farmland.
Explanation:
Answer: C: Decomposers
Explanation: The mud and pond water likely contain some sort of <em>decomposing bacteria</em>. These bacteria can break down the complex nitrogen compounds in the dead fish, <em>producing simple nitrogen compounds.</em> These simple nitrogen compounds can then be used by the plants added to the terrarium.
A is wrong because <u>producers (such as the green plants added to the terrarium) can not break down the complex nitrogen compounds</u> in the fish's body.
B is wrong for a similar reason. <em>Algae are primary producers.</em> Because of this <u>they also lack the ability to break down the complex nitrogen compounds</u> found in the fish's body.
D is also wrong. A virus may be able to infect the fish and cause disease, but <u>it lacks the ability to break down the complex nitrogen compounds </u>found in the fish's dead body.
Since A, B, and D are wrong, along with the fact that we know that decomposers <em>can</em> break down the complex nitrogen compounds in the dead fish, we can conclude that C is the correct answer.
Photosynthesis, the process whereby plants use light from the Sun to convert CO2 into organic compounds such as sugars, and oxygen, is one of the most important natural processes on Earth. This is a sophisticated system with a highly regulated shuttle traffic of ions and molecules that passes through several membranes. I hope I helped you and good luck and I am sorry I know it’s late at night it’s just I love to help people and I ate to much sugar
