Imagine two new volcanic islands spring up in the middle of the ocean. Each island is quickly founded by a few individuals of a
species of aquatic bird that requires fresh water to thrive. The two islands differ in rainfall, one wetter and one drier. Assuming that rainfall determines carrying capacity for these birds, and that rainfall is consistent over time, what might the growth curves for the bird populations look like over many years for the two islands
<em>The correct answer is the option on the upper right .</em>
Aquatic birds that require fresh water to thrive need to be around a source of fresh water. The wetter island has more fresh water than the drier island. This means that both island will be occupied from a population of zero, to an optimum stable population, which is indicated as the graph moves from zero to its maximum point, and then levels out. Th drier island will have the same pattern of curve, but will only be able to support a much smaller population, which is why the curve for the drier island is less than that of the wetter region.
Monocot, also known as monocotyledonous plants are a group of flowering plants (angiosperms) that possess one seed-leaf or cotyledon, which is contrary to the two-seed leaves possessed by dicots. Monocot plants have other characteristics that differentiate them from dicots as follows:
- Their flower parts are in multiples of three.
- It's major leaf veins are reticulated
- Pollen with single furrow or pore
However, the embryo of monocots are with a single cotyledon.
In cellular respiration it is a positive term, a process vital to life. But photorespiration is an entirely negative term because it represents a severe loss to the process of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrate synthesis.
