Question 1: logistic growth model
Answer:
a growth model that describes a population whose growth is initially exponential but slows as the population approaches the carrying capacity of the environment
Question 2: type 1 survivorship curve
Answer:
a patten of survival over time in which there is high survival throughout most of the life span, but the individuals start to die in large numbers as they approach old age
Question 3: density dependent factor
Answer:
a factor that influences an individuals probability of survival and reproduction in a manner that depends on the size of the population
Question 4: biotic potential
Answer:
under ideal conditions with unlimited resources available every population has a maximum potential for growth
Question 5: s shaped curve
Answer:
the shape of the logistic growth model when graphed
Question 6: j shaped curve
Answer:
the curve of the exponential growth model when graphed
Question 7: r selected species
Answer:
a species that has a high intrinsic growth rate, and their population typically increases rapidly
Question 8: limiting resource
Answer:
a resource that a population cannot live without and that occurs in quantities lower than the population would require to increase in size
Question 9: type 3 survivorship curve
Answer:
a pattern of survival over time in which there is low survivorship early in life with few individuals reaching adulthood
Question 10: fecundity
Answer:
the ability to produce an abundance of offspring
Question 11: exponential growth model
Answer:
a growth model that estimates a populations future size after a period of Time based on the biotic potential and the number of reproducing individuals currently in the population
Question 12: survivorship curve
Answer:
a graph that represents the distinct patterns of species survival as a function of age
Question 13: population growth rate
Answer:
the number of offspring an individual can produce in a given time period, minus the deaths of the individual or its offspring during the same period. Also Known as intristic growth rate
Question 14: type 2 survivorship curve
Answer:
a pattern of survival over time in which there is a relatively constant decline in survivorship throughout most of the life span
Question 15: k selected species
Answer:
a species with a low inartistic growth rate that causes the population to increase slowly until it reaches the carrying capacity of the environment
Question 16: population growth models
Answer:
mathematical equations that can be used to predict population size at any moment in time
Question 17: overshoot
Answer:
when a population becomes larger than the environments carrying capacity
Question 18: dieback
Answer:
a rapid decline in a population due to death also known as die-off
Question 19: density independent factor
Answer:
a factor that has the same effect on an individuals probability of survival and reproduction at any population size
Question 20: carrying capacity
Answer:
the limit to the number of individuals that can be supported by an existing habitat or ecosystem, and is denoted ad K
