- Among a population of tadpoles, the correlation coefficient for size atmetamorphosis and time required for metamorphosis is −0.74.

Describe how each of these themes define the salmon’s life cycle in no more than 2 sentences per term.What does this information tell you abou the success of certain animals (large vs. small mammals, insects, etc) within an urban ecosystem?
- 34 You have a pet fish. You have been tapping on the glass wall of its tank everymorning to say hello and then you feed your fish and watch him swim to the surfaceto eat. One evening you tap on the glass wall to say goodnight to your fish. Younotice that your fish comes to the surface of the water.Explain what type of behaviour this is and how this behaviour aids the survival of thisanimal.Answer in a sentence format.Is the following case study an r-strategists or a K-strategists? Andean condors reach sexual maturity at five to six years. Reproduction is slow; females lay only one or two eggs every other year. Offspring are cared for by both parents for at least one year. Andean condors are long-lived and can survive for seventy to seventy-five years.Imagine we census a population of rabbits (assume females only) that has been occupying a barn for a few decades. On June 30, 2021, we census the population right after the reproductive season. We count 650 individuals and divide them into 4 age classes: 0-‐6 months, 6 months-‐1 year, 1 year to 1-‐and-‐a-‐half-‐years, and 1-‐ and-‐a-‐half to 2 years. 350 are in the first age class, 175 are in the second, 90 are in the third, and 35 are in the fourth. We repeat the census at six months and find that none of the newborns (0-‐6 months age class) from the first census have produced any offspring, and that 15% of them have died. We find that the 2nd age class had 75% survival and produced 500 offspring. We also find that only 10% of the 3rd age class has survived, and produced 180 offspring. All the rabbits in the 4th age died and produced zero offspring. (a) What is the life table for this population? (i.e., x, bx, sx, lx)
