13. Many small offspring Little or no parental care and protection of offspring Early reproductive age Most offspring die before reaching reproductive age Small adults Adapted to unstable climate and environmental conditions High population growth rate (r) Population size fluctuates wildly above and below carrying capacity (K) Generalist niche Low ability to compete Early successional species r-Selected Species

15. Fewer, larger offspring High parental care and protection of offspring Later reproductive age Most offspring survive to reproductive age Larger adults Adapted to stable climate and environmental conditions Lower population growth rate (r) Population size fairly stable and usually close to carrying capacity (K) Specialist niche High ability to compete Late successional species K-Selected Species

39. Reading Population Histograms Birth rate exceeds the death rate. Population is getting larger. Pyramid shaped histogram. EX: Kenya, Nigeria and Saudi Arabia.
40. Reading Population Histograms Birth rate almost equals death rate. The population is not getting any larger or is growing very slowly. Histogram shape is straighter and more box-like until about age 45-85. EX. US, Australia & Canada has slow growth. Denmark, Austria and Italy has stable growth.
41. Reading Population Histograms When the birth rate is smaller than the death rate. The pyramid bulges near the top or is inverted . EX: Germany, Bulgaria & Hungary
