Use the information below to answer questions 15-20.
Two species of plants, the red monkey flower and the purple monkey flower, live at different elevations along a mountainside. Researchers transplanted individuals of each species to elevations where they do not normally occur; red monkey flowers (M. cardinalis) were moved up the mountain, and purple monkey flowers (M. lewisii) were moved down the mountain. At the same time, some plants of each species were dug up and replanted at their normal elevation. After one year, the researchers returned and counted the number of seeds produced by each plant as an estimate of fitness. The bar graph below shows mean number of seeds per plant at each elevation, ranging from 415 m to 3000 m. The diagram beneath this bar graph shows the elevational ranges where each species lives alone (red band for M. cardinalis and blue band for M. lewisii) and where both species live together (light-blue band).
1)True or false? In this experiment, the control group comprised the plants that were dug up and replanted at their normal elevation.
Use the graph below to answer the following question.
2)True or false? Red monkey flowers (M. cardinalis), which normally grow at lower elevations, produced fewer seeds when planted at a high elevation.
3)True or false? Purple monkey flowers (M. lewisii), which normally grow at higher elevations, perform best when grown at the highest elevation.
4)True or false? From the data, one can conclude that plants from high elevation are more adapted to conditions at high elevation than they are to conditions at low elevation.
5)True or false? The abiotic conditions at 2395 m lie within the fundamental niche of red monkey flowers (M. cardinalis).
6)True or false? The abiotic conditions at 2395 m lie within the realized niche of red monkey flowers (M. cardinalis).

Answer 1. TRUE. Because normal elevation means there natural habitat.
Answer 2. True. Because at elevation of 3000,no red flowers are seen.
Answer 3. True. Because at lower elevation of 415 purple flowers are absent whereas at 3000 elevation, purple flowers are maximum in number.
Answer 4. True, that is why there number is more at the highest elevation.
Answer 5. True.
Answer 6. True.
