Consider the following statements. Gases like oxygen and carbon dioxid...
Statement 1: Gases like oxygen and carbon dioxide dissolve better in warm water than cold water.
This statement is correct. According to Henry's law, the solubility of a gas in a liquid is directly proportional to the temperature of the liquid. As the temperature of the water increases, the kinetic energy of the water molecules also increases. This increase in kinetic energy allows the gas molecules to escape from the liquid more easily, thus decreasing the solubility. Therefore, gases like oxygen and carbon dioxide dissolve better in warm water than in cold water.
Statement 2: The rise in water temperature accelerates metabolism, and the organisms need more food to maintain this metabolic rate.
This statement is incorrect. While it is true that temperature affects the metabolic rate of organisms, an increase in water temperature does not necessarily accelerate metabolism. Different organisms have different temperature optima for their metabolic activities. Some organisms may have optimal metabolic rates at lower temperatures, while others may have optimal rates at higher temperatures. Additionally, there are upper limits to the temperature range within which organisms can survive and carry out their metabolic activities. If the water temperature exceeds this upper limit, it can lead to stress and even death in organisms. Therefore, the statement that organisms need more food to maintain a higher metabolic rate with a rise in water temperature is not universally true.
Statement 3: High water temperatures do not harm the animals living at the bottom of oceans, lakes, or rivers.
This statement is incorrect. High water temperatures can indeed harm animals living at the bottom of oceans, lakes, or rivers. Many organisms have specific temperature ranges within which they can survive and thrive. If the water temperature exceeds this range, it can disrupt their physiological processes, cause stress, and even lead to mortality. Additionally, high water temperatures can also affect the availability of oxygen and food sources for bottom-dwelling organisms. Therefore, it is incorrect to assume that high water temperatures do not harm animals living at the bottom of aquatic ecosystems.
In conclusion, only the first statement, which states that gases like oxygen and carbon dioxide dissolve better in warm water than cold water, is correct. The second statement about the rise in water temperature accelerating metabolism and organisms needing more food to maintain this metabolic rate is incorrect. Similarly, the third statement about high water temperatures not harming bottom-dwelling animals is also incorrect.

Consider the following statements. Gases like oxygen and carbon dioxid...
Only statement 2 is correct.
- In a warming world, marine creatures are in danger of suffocating. Gases like oxygen and carbon dioxide dissolve better at colder temperatures, so that means the warmer the water, the less oxygen is available to breathe.
- Conversely, higher temperatures also cause an increase in metabolism, which in turn means animals have to breathe even more than usual.
- The rise in temperature accelerates metabolism, and the organisms need more food to maintain this metabolic rate.
- Algal blooms are more common in hotter waters too. Such blooms can further deplete oxygen levels and produce toxins harmful for fish, marine mammals and birds, for instance.
- High water temperatures are most harmful for animals living at the bottom of oceans, lakes or rivers. These benthic species include corals, mussels, sponges, starfish and plants like sea grasses, and are often attached to rock or solid ground. They can’t migrate when it gets too hot.
