| A | B |
|---|
| Why would adaptations that an organism has to the environment not be an example of coevolution? | Coevolution is an adaptation that an organism has adopted in response to another organism, not the environment |
| Would all plants in a field be an example of a population? Why? | No. A population is a reproductive group and all plants in a field are nopt capable of reproducing together |
| What is the definition of density? | The number of individual per unit area. |
| What is a parasite? | Organism that lives in or on another organism and feeds opn the organism. Parasites usually do not kill the host. However, it is often weakened or exposed to disease by the parasite. |
| Know what a predator/prey relationship is. | When an organism kills and feeds on another organism. |
| In what relationship do both species benefit? | Mutualism. |
| In what relationship do one species benefit while the other is neither harmed nor helped? | Commensalism. |
| What kind of dispersion would a herd of cows be? | Clumped. |
| What most likely will cause a large number of density-independant deaths? | Natural disaster. |
| What is exponential growth? | A dramtic increase in a population over a small amount of time. |
| This is one thing that is commonly confused with an organism's niche. | An organism's habitat. |
| What has the greatest effect on reproductive potential? | Reproducing earlier in life. |
| The carry capacity of an environment for a particular species at a particular time is determined by what? | Supply of the most limited resources. |
| What is symbiosis? | A relationship in which two organisms live in close association. |
| What are the properties used to describe a population? | Number of individuals, relative distribution or arrangement of its individuals, and the density of the individuals. |
| Where can food competition occur? | Between two populations, among member of the same population, among populations whose niches overlap. |
| What limits the population's biotic potential? | Each individuals reproductive potential. |
| What is biotic potential? | Fastest rate at which a population can grow. |
| What is reproductive potential? | Maximum number of offspring that the individual member of a population can reproduce. |
| What is the difference between a parasite and a predator? | A predator kills and consumes its prey. |
| This is decribed as even, clumped, or random. | Population's dispersion. |
| What is indirect competition? | Organisms can compete even if they never come into direct contact. |
| What is an organism's generation time? | The age at which an organism can reproduce. |
| What is the carrying capacity for an environment? | The maximum number of species that if can support indefinitely. |
| What is a limiting resource? | A resouce that a species consumes at the same rate that the ecosystem replenishes it. |
| What are two ways that members of a species compete indircetly for resources? | Competing for a territory and social dominance. |
| A disease would be what time of population regulation? | Density-dependant |
| What is included in a species' niche? | The species physical home, the environment al factors necessary for the species' survival, and all its interactions with other organisms. |
| What is the type of interaction is which both species are harmed? | Competition. |
| What is it when each species uses less of a niche than it is capable of using, in order to reudce competition for resouces with other species? | Niche restriction. |
| What is the growth rate formula? | Birth rate minus its death rate. |
| What are the three types of growth rates? | Positive, negative, zero. |
| If the population of a prey drastically increases what will happen to the predator? | the population of predator will increase also |
| If the population of a prey drastically decreases what will happen to the predator? | the population of predator will decrease also |
| How can two species compete for the same resource without coming into contact? | Species can compete over time or space without meeting by utilizing the same resource at differnet times. Example:nocturnal animals. |
| List three reproductive behaviors of individual members of a species that affect the reproductive potential of a species? | Producing more offspring at a time, reproducing more often, reproducing earlier in life. |
| Know three density-dependant and density-independant causes of death. | Density-dependant:limited resources, predation, and disease. Density-independant:severe weather, and natural disasters. |
