Ecoystem Stability Practice
1) Explain how the stability of the ecosystem changes from the healthy left side to the unhealthy right side.
2) Make a claim as to whether the right side could ever “heal.”
3) Justify your claim with evidence and scientific reasoning from this lesson and your prior learning.
Is Sustainable Development Goal realistic or idealistic? Why or why not? Give examples that support your point of view.

- WHAT IF? Why is nutrient availability in a tropical rainforest particularly vulnerable to logging?arrow_forwardCER SCENARIO #1 This ecosystem is being affected by the development of a neighborhood. Acres are being cleared for building homes and roads. The people who have already moved in are complaining about the foxes that have been going through their yards and have even tried to catch small cats and dogs as prey. It was decided that the foxes would be trapped and relocated far away from the new neighborhood. PROMPT: WRITE A CLAIM STATEMENT ABOUT WHAT COULD HAPPEN TO THIS ECOSYSTEM WITH THE REMOVAL OF THE FOXES. CLAIM: EVIDENCE: REASONING:arrow_forward(A) The above figure indicates how much biologically productive land is needed to support different activities (e.g. 'carbon' is land needed to offset carbon emissions from energy production; 'cropland' is land needed to grow crops for food). What Goes it say about the sustainability of our lifestyle? Explain. (B) The world's ecosystems provide many valuable services, that we all benefit from. Yet, these services are often undervalued and taken for granted. Why? For full credit, provide an example with at least one specific ecosystem service. (C) Humans are impacting ecosystems (and their services) in many ways, often negatively. Throughout this course we've discussed some simple actions that can be taken by individuals to help mitigate our impact on the environment. List one action and specify how it can help.arrow_forward
- Hello, I needed help with this. I was aiming for a more simplistic answer. Thank you!arrow_forwardUnit 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 nichesarrow_forwardUrban forests, green roofs, parks, and other green spaces can improve environmental conditions for city dwellers in a number of ways. (g) In addition to improving air quality and reducing energy usage in cities, increasing the amount of vegetation can decrease urban runoff. Describe one way increasing the amount of vegetation in cities can lead to decreased runoff. (h) Describe one cultural benefit that may result from increasing the amount of vegetation in cities.arrow_forward

How long do you think it will take to return to the original biodiversity of the first ecosystem based on the tree trap solution and why?arrow_forwardExplain the solution for the removal of water flies.

- Explain the term environmental sustainability?arrow_forwardA given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day. Does this ecosystem follow Lindeman's Law for ecological efficiency? No, the average efficiency is 20% O Yes, the average efficiency is 10% O No, the average efficiency is 10% O Yes, the average efficiency is 20%arrow_forwardNeed helparrow_forward
