C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
Answer:
Ocean plays the role of regulator.
Explanation:
The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.

Answer:
Cheaper to purchase than organic
Nutrients are concentrated, only small amounts needed
Nutrients are quickly available for plant absorption
Answer:
They're faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.
if the pressure of a sample of gas is doubles at constant temperature, what happens to the volume of the gas?
Answer:
If the pressure doubles, the volume decreases in half.
Explanation:
The relationship between the pressure and the volume of a gas can be explained by Boyle's Law. According to this law, the volume and pressure of the gas has an inversely proprietary relationship. In that case, if the pressure on the volume decreases in the same intensity and if the pressure decreases, the volume increases in the same proportion. In that case, if the pressure of a gas sample doubles, the volume decreases by half.
