Concept explainers
To discuss: The ecological effects of manmade steel barriers between two countries.
Concept introduction:
In general, barriers mean limit or boundary. Ecological barriers are the natural limits that split one ecosystem from another ecosystem. These barriers are used for safety purpose. Some artificial barriers are also used to prevent the uncontrolled movement.
To determine: The type of organisms that would be adversely affected by fragmentation.

- Humans obviously contribute a lot of impacts in the ecosystem. Give two common mistakes that humanity do in degrading the ecosystem processes and services and briefly discuss a way to solve and stop these destructive activities.arrow_forwardExamine the situation below. What function/services of the ecosystem is highly depicted in this situation? Justify. For 3-5 sentences only* One of the wetland ecosystem which is subjected to this degradation and considered as heavy polluted lake in the Philippines Laguna de Bay (LDB) (Framework for Philippine Plant Conservation Strategy and Action Plan retrieved 2018). LDB is the largest lake in the country and amongst the largest in Southeast Asia. It is a significant natural resource, being the catchment of an expansive and environmentally important watershed (Israel 2007). The shorelines of LDB serve as important locations for industrial, commercial and tourism activities in the country. It plays an ecological importance because it serves as spawning areas for fish and a natural protection from floodsarrow_forwardExplain the solution for the removal of the Spotted Lanternfly. How will this solution affect the native species, economy and/or social impacts? How long do you think it will take to return to the original biodiversity of the ecosystem based on the solution and why?arrow_forward
- CER 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_forwardsupport or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer. Shark fin soup can cause the collapse of coral reef ecosystemarrow_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_forward

Suggest possible solutions that would reduce the impacts of nutrient and pesticide runoff, while incorporating the three considerations of human sustainability. In other words, come up with a solution that would reduce ecological impacts of pesticide and nutrient runoff, while allowing farmers to ultimately meet their income needs in a socially equitable way (does not exploit anyone in the process). • Show lessarrow_forwardHabitat loss and fragmentation has caused severe damage to a particular type of ecosystem. Name it.arrow_forwardExplain the solution for the removal of water flies. How will this solution affect the native species, economy, and/or social impacts?
