Which point on the curve in the diagram above best represents the carrying capacity of. Few plants in the forest can successfully regenerate in the deep shade of an unbroken canopy; many tree species are represented there only as a population of slender, slow-growing seedlings or saplings that have no chance of growing to the well-lit canopy unless a gap forms. The world's bird population is definitely decreasing. The trees that initially fill in the gap in the canopy live approximately one century, whereas the slower-growing trees that ultimately replace them may live for 200 to 500 years or, in extreme cases, even longer.

An unusual mix of trees of different sizes is found in the tropical rainforest, and those trees form several canopies below the uppermost layer, although they are not always recognizably separate layers. Some of these are fierce (lions, sharks, tigers). Such an occurrence permits more solar radiation to reach their level and initiates rapid growth and competition between saplings as to which will become a part of the well-lit canopy. Plants with similar stature and life-form can be grouped into categories called synusiae, which make up distinct layers of vegetation. The rainforest is home to many birds, such as toucans, macaws, parrots, hummingbirds and Harpy Eagles. Describe two criteria a student can use when determining which college or university to attend. Stranglers make up a type of synusia virtually restricted to tropical rainforests.
