Question

what term describes the pattern of distribution where individuals are randomly arranged in an ecosystem? a. clumped dispersion b. random dispersion c. linear dispersion d. uniform dispersion what type of relationship is illustrated when the populations of wolves and deer exhibit cyclical increases and decreases over time? a. predator - prey relationship b. commensalism c. competition d. mutualism humans are generally considered which type of species based on their life history strategy? a. non - selective b. r - selected c. k - selected d. r/k intermediate

Explanation:

1. In an ecosystem, when individuals are randomly arranged, it is called random dispersion. Clumped dispersion is when they are grouped together, linear dispersion is not a standard ecological dispersion term, and uniform dispersion is when they are evenly - spaced.
2. Wolves are predators and deer are prey. Their populations show cyclical increases and decreases as the number of predators affects the number of prey and vice - versa. Commensalism is a one - sided beneficial relationship, competition is between species for resources, and mutualism is a mutually beneficial relationship.
3. Humans are K - selected species. K - selected species have few offspring, invest a lot in parental care, and have a long lifespan, which is characteristic of humans. R - selected species have many offspring with little parental care. Non - selective is not a relevant life - history strategy term here, and R/K intermediate is not the typical classification for humans.

Answer:

1. b. Random dispersion
2. a. Predator - prey relationship
3. c. K - selected
