In deep water, which of the following abiotic factors would most limit primary productivity?

Use the following figures to answer the question below. The figure depicts average temperatures and total precipitation across the 12 months of the year. Annual precipitation in Area 1 is approximately 260 cm, and in Area 2, 10 cm. Based on the data in the figures, which of the following statements is most consistent with the data?

In creating global climate patterns, which of the following factors is most likely the primary cause of all of the other factors that are listed?

Which aquatic biome listed here is one of the most productive on Earth, and why?

Which of the following areas of study focuses on the exchange of energy, organisms, and materials between ecosystems?

What is most likely to happen to the seasons if Earth were tilted 35 degrees off its orbital plane instead of the usual 23.5 degrees?

Use the following figures to answer the question below. The diagram is a climograph, which depicts the most likely overlap between mean temperatures and precipitation values that result in the given types of biomes. East of the Mississippi River in Hopkinsville, Kentucky, the mean annual precipitation is 130cm. The mean annual temperature is 14.3°C. In the winter, the mean temperature is 7.3°C, while in summer it is 20.6°C. Using the climograph shown here, the biome found in Hopkinsville is most likely a ________.

Turnover of water in temperate lakes during the spring and fall is caused by which of the following?

Use the diagram showing the spread of the cattle egret, Bubulcus ibis, since its arrival in the New World, to answer the question. The range of cattle egrets has expanded between 1937 (dark region in South America) and today, as depicted in the map with lighter shades indicating more recent advancements of the egret over time. Which of the following claims best explains the expansion of the cattle egret range?

At 15-30°N, air masses formed over the Pacific Ocean are moved by prevailing westerlies, where they encounter extensive north-south mountain ranges over continents. Which statement best describes the result when an air mass encounters a landform?

Which of the following is a mechanism by which ocean ecosystems affect the biosphere?

The main reason polar regions are cooler than the equator is that ________.

Subtropical plants are commonplace in Land's End, England, however, at the equivalent latitude of Labrador in coastal Canada, the local flora is instead subarctic. Which statement best explains why this apparent anomaly exists between North America and Europe?

As temperatures rise due to global climate change, plant species' ranges in the southern hemisphere may move further southward. Which of the following is a characteristic of plants that would most likely allow them to avoid extinction by moving southward under climate change?

Which of the following statements best describes the interaction between fire and ecosystems?

Which of the following best explains why the actual vegetation that is present in a particular biome may not match the prediction of a global biome map that was generated by modeling the temperatures and precipitation expected at a given latitude?
