The correct answer is - c. sunlight.
The sunlight, or rather lack of it, is the biggest limiting factor for growth on the floor of the rainforests. The dense canopies of the higher trees block the sunlight to reach the floor of the rainforest, thus the plants growing in the shades are much smaller, have become specialized for life without or with very little sunlight. They are not able to compete with the trees that are very high to reach the upper parts of the forest and get direct sunlight, so they are on the floor, in the shades. In fact these plants have become so specialized to life without sunlight that if the big trees are removed and they are exposed to the sun they will not manage to survive.

Answer:
it is because, igneous and metamorphic form at temperatures and pressures which destroy the fossil remains. dead organisms may become sediments which may, under right conditions, become sedimentary rocks
Over time, pressure continues to build in the tectonic plates, until suddenly, they shift in an earthquake. Aftershocks are common, but then a long time can pass before another one becomes likely.
<span>The Global Surface Temperature is Rising
</span>NOAA states:<span>Many lines of scientific evidence show the Earth's climate is changing. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming. It is worth noting that increasing global temperature is only one element of observed global climate change. Precipitation patterns are also changing; storms and other extremes are changing as well.
