Complete Question:
I made the grass diseased. This caused all of the populations above it (rabbit, snake, and hawk) to rapidly decrease over the 12 month period
(a) A major disturbance that the ecosystem was able to recover completely from __________
(b) A major disturbance that caused the ecosystem to stabilize at a new equilibrium ____________
(c) A major disturbance that caused the ecosystem to completely collapse __________
ANSWER:
(a) reducing the hawks to nearly zero
(b) removing all of the hawks
(c) removing all the diseased.
Explanation:
(a) reducing the hawks to nearly zero will cause low depletion of the producer (plants) and this will allow the plant to grow (without visible depletion) over a period of time.
(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there's no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.
(c) for ecosystem to collapse, it's important to note that the removal of the producer (plants) will be bring about the loss of the ecosystem. Since, their is no manufacturer of food, the primary consumer (rabbit) in the food chain will be starved and overtime the rabbits will be wiped out and this will caused the loss of secondary and tertiary consumer in the long run.

Answer:
When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
Explanation:
You might expect that sheltered areas of stone buildings and monuments would not be affected by acid precipitation. However, sheltered areas on limestone and marble buildings and monuments show blackened crusts that have peeled off in some places, revealing crumbling stone beneath. This black crust is primarily composed of gypsum, a mineral that forms from the reaction between calcite, water, and sulfuric acid. Gypsum is soluble in water; although it can form anywhere on carbonate stone surfaces that are exposed to sulfur dioxide gas (SO2), it is usually washed away. It remains only on protected surfaces that are not directly washed by the rain.
On the Galapagos Islands, Darwin also saw several different types of finch, a different species on each island. ... Finches that ate small nuts and seeds had beaks for cracking nuts and seeds. Darwin noticed that fruit-eating finches had parrot-like beaks, and that finches that ate insects had narrow, prying beaks.
