Pond B Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. True Felco If we add 3 Black Herring to Pond A and over time the number of Black Herring returns to 2, then the carrying capacity of Black Herring in Pond A is 5.

Fertilization & deposition Crop export Watershed Leaching & Runoff Mineralization The figure above shows major N inputs and outputs for a watershed dominated by corn/soybean production. Given an annual change in N storage of 1200 Mg yr for the watershed, calculate the rate of leaching & runoff. To answer this question, assume also the following rates (in Mg yr): fertilization & deposition = 4000; mineralization = 4900; and crop export = 5400. %3! Your Answer: Answer
14 R F5 Q5.4. Researchers conducted an experiment to determine whether nitrogen or phosphorus is limiting algal growth in a lake. They estimated algal population size under the baseline input level for each nutrient (1X), as well as when nutrient input was doubled (2X), tripled (3X), and quadrupled (4X). Based on their results, which are plotted below, which nutrient (if any) is limiting algal growth? 5 Algal population size 1001 80- 60- 40- 20- 0+ T Submit F6 O 2 3 Nitrogen Input (X baseline) A Di Algal growth is limited by nitrogen. Algal growth is limited by phosphorus. Algal growth is not limited by either nutrient. There is not enough data to determine what limits algal growth.

True Falce For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. If Pond C is cooled to 10°C and the Stripey-Orange Clownfish die, then 10°C must be below the Stripey-Orange Clownfish's range of tolerance for temperature. △ 英拼
Nearpod-12.17.20 Rea Signed in as: Aiden Hun Q Review / v Finish Tes ABC Question 3 A scientist claims that orchid populations will be smaller in areas that have an average spring temperature of 9°C compared to areas that have an average spring temperature of 7°C. Which argument BEST supports this claim? Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is lower. This will result in decreased orchid reproduction and smaller populations. A re Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is lower. This will result in increased orchid reproduction and smaller populations. Orchid populations will be smaller at higher temperatures because the probability of male pollinating bees arriving before orchid flowering is greater This will result in increased orchid reproduction and smaller populations.
