APES MC Make up
This biome contains plants that are adapted to prevent water loss due to the low average rainfall and high temperatures year-round.
Desert: Deserts are hot and dry year-round, and plant species are adapted in a variety of ways (small leaves, stems that store water, and modified spines) to reduce water loss.
Which of the following is a biome found at 30° N and 30° S as seen in the diagram?
Desert: Deserts form where dry air descends from the upper atmosphere, heating up as it does so.
Which of the following correctly pairs a greenhouse gas with its primary anthropogenic source?
Nitrous Oxide and Agricultural Practices: The primary anthropogenic source for nitrous oxides is agriculture, including fertilizer use and manure decomposition.
Which of the following is the source of energy driving the circulation pattern labeled C in the diagram?
Solar energy: The light warms Earth's surface, creating rising air currents, as seen in the diagram.
The thick forest of this biome tends to be well adapted to short growing seasons.
Taiga: Taiga forests are located primarily between 50° and 60° N and are dominated by coniferous trees that are well adapted to the relatively short growing season of these latitudes.
The terrestrial biomes shown in the diagram above vary in net primary productivity. The explanation for the variation includes which of the following? 1. Temperature 2. Precipitation 3. Longitude
Temperature and Percipitation: both effect phtosynthesis
Losses of usable energy between successive trophic levels in an ecosystem are best accounted for by which of the following?
The Second Law of Thermodynamics:As energy is transferrred and transformmed more and more enrgy wasted, relased as thermal energy
El Niño, a periodic warming of ocean surface waters, occurs in which of the following regions?
Tropical East Pacific: Surface water in the equatoral Pacfic becomes ware than average and East winds blow weaker than normal
This biome has the highest net primary productivity, in part because of consistently warm temperatures and abundant sunlight.
Tropical Rainforest: Tropical rain forest has a net primary productivity of about 2000 g C/m2/year . Net primary productivity is highest where temperatures are consistently warm, water is abundant, and day length is consistent all year. The tropical latitudes meet these conditions better than the latitudes of the other biomes.
Which of the following is a primary cause of El Niño climate variations?
Warmer Surface Waters in the Pacific Ocean: Shifts in westward trade-wind currents result in warmer surface waters in the northern Pacific, which cause El Niño.
