user: input: Please answer the following: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It’s rate of loss has slowed with restrictions on pollutants, but it is still at risk.  Two neighboring planets identical to Earth in size and atmospheric conditions behaved differently towards their environments. Planet A emitted a lot of air pollution, destroying its ozone layer, while Planet B respected the environment and used ecological products.  Which planet had lower levels of UV reaching it?
++++++++++
output: Planet B


input: Please answer the following: Biodiversity loss is the extinction of species (plant or animal) worldwide, and also the local reduction or loss of species in a certain habitat.  The latter phenomenon can be temporary or permanent, depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration / ecological resilience or effectively permanent (e.g. through land loss). Global extinction has so far been proven to be irreversible.  Even though permanent global species loss is a more dramatic phenomenon than regional changes in species composition, even minor changes from a healthy stable state can have dramatic influence on the food web and the food chain insofar as reductions in only one species can adversely affect the entire chain (coextinction), leading to an overall reduction in biodiversity, possible alternative stable states of an ecosystem notwithstanding. Ecological effects of biodiversity are usually counteracted by its loss. Reduced biodiversity in particular leads to reduced ecosystem services and eventually poses an immediate danger for food security, also for humankind.[1]  Two islands of identical size with similar ecosystems experienced different destinies. Caribu island, inhabited by more natives, hunted a few of the animal species there, contributing to the extinction of a few. People from Hiji island, were pescotarian, and hardly ever fished.  Which island exterminated more species of animals?
++++++++++
output: Caribu


input: Please answer the following: Precipitation in grasslands is equal to or less than evapotranspiration and causes soil development to operate in relative drought. Leaching and migration of weathering products is therefore decreased. Large amounts of evaporation causes buildup of calcium (Ca) and other large cations flocculate clay minerals and fulvic acids in the upper soil profile. Impermeable clay limits downward percolation of water and fulvic acids, reducing chemical weathering and podzolization. The depth to the maximum concentration of clay increases in areas of increased precipitation and leaching. When leaching is decreased, the Ca precipitates as calcite (CaCO3) in the lower soil levels, a layer known as caliche.  Monsoon plays a big role in shaping local climates. In some places of the Horn of Africa monsoon causes heavy rainfall. But across the Red Sea the Arabian Peninsula mostly misses the monsoon. As a result, they have minimal rainfall throughout the year.  In which place less calcite would precipitate in the lower soil levels, Horn of Africa or Arabian Peninsula?
++++++++++
output: Horn of Africa


input: Please answer the following: Acromyrmex heyeri is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Acromyrmex. Acromyrmex heyeri workers construct the colonies nest by thatching together cut grass. At temperatures ranging from 20–30 °C, workers created more openings in the nest thatch as the internal nest temperature goes up as a method of temperature regulation for the colony. The workers will close openings in the nest thatch as the air humidity surrounding the nest decreases to reduce water loss for the colony.  Ants are one of the most interesting creatures on earth. David wants to study ants for his biology project. He is specifically interested in ant species Acromyrmex heyeri. This semester he studied this ant in Americas.  First day when he studied the ants the temperature was 10 degree Centigrade. In the second day of his study the temperature rose to 25 degree Centigrade. In the third  day of his study the air humidity was high. But in the fourth day of his study air humidity dropped. David wants to continue his study of this same ant species in Asia next semester.  Which day David would see openings in the nest hatch open, third day or fourth day?

output:

assistant: third day
