Textbook Question

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

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?

He then observed how the community changed in response to the loss of starfish by comparing the diversity of the community in the pools where starfish had been removed to the diversity in pools where he had let the starfish remain. By removing starfish from some pools, what global change driver was Robert Paine investigating? overexploitation pollution climate change invasive species habitat lossarrow_forward

Your Goal: Using the model ecosystem you have just created, you will generate one food chain/web. Method 1. Using your model, show 1 food web that contains at least 8 elements. You must include a producer, consumer and a secondary consumer. They must be realistic feeding relationships! (You may need to add an element to your ecosystem model). Remember, a food web contains many food chains; make sure your consumers have a variety of food to eat. a primary Önly for the elements in your food web - add to their labels whether it is a producer or consumer.

(If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.)
