Midterm Review Assignment
Taboo (x5):
1. Carrying Capacity
2. R-selection and K-selection
3. Standard Deviation
4. Standard Error
5. Bivariate Regression
Define it (x5):
1. Population Dynamics: How populations change over time and the factors that influence
the decrease, maintenance, or increase of populations over time.
2. Dispersal: Dispersal involves the movement of individuals from one location to another,
and it can lead to changes in population densities. Various mechanisms, such as wind,
animals, or water, can facilitate dispersal.
3. Metapopulations: Metapopulations are composed of distinct subpopulations, connected
by occasional gene flow, collectively forming a "population of populations" where
subpopulations can serve as sources or sinks, and maintaining connectivity is vital to
prevent local extirpation.
4. Survivorship Patterns: Survivorship patterns in populations, represented by survivorship
curves, illustrate the distribution of individuals' life spans within a population.
5. Ecological succession: Change in an ecological community following a disturbance
event.

carrying capacity (K) and exhibits an S-shaped sigmoid curve?
a. Exponential growth model
b. Continuous Time Model

d. Variable vs Parameter Model
2. Which of the following biomes is characterized by a treeless landscape, very short
growing seasons, and low temperatures with mostly below-zero temperatures?
a. Tropical Rainforest

3. Which type of selection favors the average phenotype and goes against extremes?
a. Directional selection
b. Disruptive selection

d. Random selection
4. Which type of organisms generate little or no metabolic heat and have their body
temperature determined by available environmental temperatures?
a. Endotherms
b. Ectotherms
c. Poikilotherms
d. Homeotherms
5.
Which of the following terms refers to the process of an organism producing multiple
offspring with smaller individual sizes due to limited energy resources?
