Over the years, the winter coloration (the color of the rabbit's fur) of the surviving rabbit population changed. The graph shows the change in winter coloration of rabbits between 185 to 2000. Based on the data, we could hypothesize that A) the winters are longer in length. B) the snowshoe rabbit has migrated to another area. the amount of snow cover varied over the years. D) more snowshoe rabbit predators have moved into Manitoba. % PopulationNumber of rotifers 4500+ 4000- 3500 3000- 2500- 2000- 1500- 1000- 500- 0 Key x Rotifers alone (flask X) • Rotifers when living with water fleas (flask Z) 2 0 2 X -+ 4 Yo * X X X 6 8 10 12 14 16 18 Day Analyze the graph and identify some factors that may contribute to the rotifer population leveling off in the absence of water fleas.

Why does the population of tree snails experience a drop after the initial increase? 000 snails were not adapted to living in captivity authors attribute the increase of genetic diversity to the population drop a viral infection decimated the snail population in 2009 and consecutive years a genetic bottleneck led to reduced genetic diversity and fecundityS2) Below are two tables showing the population size and deaths by age for one year in the states of Louisiana (LA) and Florida (FL).

The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.A population of 300 fairy wrens colonizes a cloud forest without any other wrens in it.
