Unit B - Rainforests are being clear-cut in order to make room for more profitable
crops that can be used as biofuels. In Brazil, a monoculture consisting of fields of
soya beans is being planted, replacing the native rainforest ecosystem that often
consists of thousands of species.
Unit B - Compare the previous rainforest ecosystem and the new monoculture
ecosystem with respect to biodiversity and population size.
Your response should include
· an explanation of biotic limiting factors
an explanation of abiotic limiting factors
a discussion of the availability of habitats and niches
The figure below shows the relative abundance (y axis) of shrubs in an ecosystem in the years
following a fire (x axis). The shrubs in this ecosystem fall into two functional groups: fıre recruiters
and fıre persisters.

Despite the intensity of the fire, some soils remained. Total biomass, species richness, and net productivity were reduced significantly after the initial disturbance. There have not been any more fires since. Twenty years after the fire, there are medium-sized trees and bushes growing, as well as ferns and flowering plants. The forest is in the middle, or intermediate, stage of succession. How has the current stage of succession affected total biomass, species richness, and net productivity of the ecosystem?
