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_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_forwardInvasive species have the greatest impact on (small or large?) ecosystems. Why?arrow_forward
- support 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_forwardDescribe why biodiversity is important to ecosystem health, even in an agricultural setting where mo… Show more Describe why biodiversity is important to ecosystem health, even in an agricultural setting where most often farmers are paid for a single, pure product like wheat or corn. 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_forward
