Question

1. scientists monitored a coral reef for several decades. as the temperature steadily increased, the coral was able to maintain consistent populations of organisms. however, when the temperature increased to its peak point, the number of species in the ecosystem drastically declined. even after the temperature stabilized, the ecosystem showed few signs of recovery. which statement best describes this ecosystem? a. the ecosystem was resistant but not resilient. b. the ecosystem was resilient but not resistant. c. the ecosystem was both resilient and resistant. d. the ecosystem was neither resilient nor resistant. 5. which of these best describes a climax community that results from succession? a. a forest of hardwood trees b. a mixture of pine trees and oak trees c. trees that are all mature d. depends on the biome 6. select the correct terms to complete the statement about ecosystem disturbance. if an ecosystem is resilient | resistant, it is generally stable unless drastically changed by a disturbance. when a disturbance causes a change, the ecosystem quickly recovers when it is resilient | resistant. 7. if you look closely at an image of a clear - cut forest, you can see that clear - cutting does more than just remove trees from an ecosystem. what other effects will clear - cutting have on this ecosystem? select all correct answers. a. runoff will affect the stream ecosystem. b. erosion will remove nutrient - rich topsoil. c. nutrients continue to cycle into the soil. d. some animal populations will move away.

Explanation:

4.

• Resistance: Refers to an ecosystem's ability to maintain its structure and function in the face of a disturbance. The coral reef was able to maintain consistent populations as temperature increased steadily (showing resistance).
• Resilience: Refers to an ecosystem's ability to recover after a disturbance. The coral reef did not recover (number of species did not bounce back) after the temperature peak (showing lack of resilience).

• A climax community is the final stage of ecological succession. It is stable and self - perpetuating.
• Different biomes (e.g., tropical rainforest biome, temperate forest biome) will have different climax communities. For example, a tropical rainforest biome will have a climax community with different species composition compared to a tundra biome.

• Resistant ecosystem: A resistant ecosystem is able to maintain its state (be stable) when faced with a disturbance.
• Resilient ecosystem: An ecosystem that is resilient can recover quickly after a disturbance.

Answer:

a. The ecosystem was resistant but not resilient.
