Populations: Question & Answer Question Individuals of a species living in the same place at the same time? Changes in a population over time? The amount of individuals in a population per unit habitat area? Spatial pattern of distribution where the individuals are grouped or clustered together? Spatial pattern of distribution where the individuals are evenly spaced throughout the area? Spatial pattern of distribution where the individuals are randomly throughout the area because of resource locations? This shape of age structure diagram shows positive population growth? This shape of age structure diagram shows zero population growth? This shape of age structure diagram shows negative population growth? Exponential growth results in a graph of what shape? The change in population over time (growth rate) is represented by this letter? This equation/rule helps a scientist determine the amount of time required for a population to double in size? These factors affect populations randomly; examples include fire, drought, flood? These factors affect populations with high density (large numbers); examples include disease and interactions like competition/predation, etc. Logistic growth results in a graph of what shape? The number of organisms an environment can support? Carrying capacity is represented by this letter? This type of species gives birth to many offspring because they provide little care/protection and this results in most offspring dying before reaching reproductive age? This type of species gives birth to fewer offspring because they provide a lot of care/protection so much of the offspring survive to reproductive age? This type of graph shows the relationship between age and mortality? This type of survivorship curve is representative of r-selected species? This type of survivorship curve is representative of K-selected species? Population sampling technique that is best used for evenly distributed plant populations? Population sampling technique that is best used for animals, requires researchers to perform several “captures” of the population in study? Answer
