Answer:
D. Carbon dioxide and water vapor
For example, animal cells<span> do not have a </span>cell<span> wall or chloroplasts but </span>plant cells<span> do. Plant and </span>animal cells<span> are </span>both<span> eukaryotic cells, so they have several features in Vacuole, One or </span>more<span> small vacuoles (much smaller than </span>plant cells<span>). 6 Video Comparing Plant and </span>Animal Cells<span>; 7 </span>Types of plant cells<span>; 8 References</span>
Since the species is not reaching its maximum population, we can think that there is an inhibiting factor in the ecosystem. So if more organisms were to migrate within the population or if the birth rate were to increase, the population would not follow the trend in the image. If the resources of the ecosystem were limited, the population would increase, but then they would start to die due to lack of resources so the graph would have a gaussian bell distribution.
Therefore, the answer is D, since the maximum load of the ecosystem has been reached and although the organisms continue to reproduce, the population cannot increase but neither does it decrease since there are sufficient resources.
Saturn is an outer planet
The word you're looking for is Exoskeleton. The outer covering is called an EXOSKELETON which is a hard covering on the outside of the body that provides both support and protection. The exoskeleton is made of CHITIN. Some exoskeletons are leathery like caterpillars, and some are tough and hard like ticks and crabs.
