Trophic Cascade - Powerful indirect interactions that can control entire ecosystems., Species Interactions - Describe the relationships among organisms of different species living in the same location., Birth/Death and Population Change - A population of organisms will grow when its birth rate exceeds its death rate. If the birth rate and death rate are the same, then the population will not grow but will remain constant. If the death rate exceeds the birth rate, the population will decrease., Growth Rate - A change in population. , Reproductive Potential - The capacity of a species to reproduce itself under optimum conditions., R-Strategists - Values quantity over quality. Energy spent creating lots of babies, not so much parenting., K-Strategists - Produce offspriProduce fewer offspring, which often require extensive parental care until they mature. , Exponential Growth - Growing or increasing very rapidly., Carrying Capacity - An ecosystem's maximum number of organisms of a species that can survive in that particular environment., Population Overshoot - The growth of a population beyond the environment's or ecosystem's ability to support that species., Density-Dependent Limiting Factors - Factors that cause a population's per capita growth rate to change—typically, to drop—with increasing population density, such as competition for food and resources, disease transmission, predation, and territoriality/aggression., Density-Independent Limiting Factors - Any force that affects the size of a population of living things regardless of the density of the population, such as storms, droughts, floods, earthquakes, human activity, and other disasters. ,
