Answer:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen.
Explanation:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen. By respiration, O2 is removed from the atmosphere and replaced with CO2. However, these processes are not balanced. Some organic matter is not oxidized. (I'm very sorry if I'm wrong but I believe it's that)
The answer is <span>d. homologous structures.
Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
The last option is corrrect because when one species move away from an environment or die it lead to decrease in biodiversity as well as the overall health of ecosystem also decreases.
