Row 1, Col 1 This describes how individuals in a population are distributed. Clumped(humans), uniform(trees in an orchard), or random(trees in a forest). What is dispersion?

1,2 This kind of growth is shown in the following graph. What is exponential growth?

1,3 When two species compete for exactly the same resources, one is likely to be more successful. What is the competitive exclusion principle?

1,4 When two or more species resemble one another in appearance. What is mimicry?

2,1 An example of type II survivorship curves, which describe organisms in which the length of survivorship is at random, that is, the likelihood of death is the same at any age. What are rodents? (Also, certain invertebrates-Hydra)

2,2 A factor, which has made exponential growth possible, includes advances in medicine, such as the discoveries of antibiotics,vaccines, and proper hygiene. What is reduction in disease?

2,3 By pursuing slightly different resources or securing their resources in slightly different ways, individuals minimize and maximize success. What is resource partitioning?

2,4 A conspicuous pattern or coloration of animals that warns predators that they sting, bite, taste bad, or are otherwise to be avoided. What is aposematic(warning) coloration?

3,1 The following graph is a description of the abundance of individuals in a particular age group. It shows a slight growth in population. What is an age structure diagram?

3,2 Species whose population remains relatively constant (at the carrying capacity). What are K-selected species?

3,3 A term applied to two species that live together in close contact during a portion (or all) of their lives. What is symbiosis?

3,4 Any color, pattern, shape, or behavior that enables an animal to blend in with its surroundings. What is camouflage (cryptic coloration)?

4,1 Elements that prevent a population from attaining its biotic potential. What are limiting factors?

4,2 The growth of a population can be described by this equation. What is r=(births-deaths)/N

4,3 The niche that an organism occupies in the absence of competing species. What is a fundamental niche?

4,4 Toxic chemicals produced in the plant that discourage would-be herbivores. (Type the question for 4,4 here.)?
