Question	Answer
This occurs when species may evolve adaptations that reduce the harm or improve the benefit of the relationship with other species	coevolution
All maple trees in a forest is an example of	population
The density of a population is	the number of individuals per unit area
example of a parasitic relationship	a roundworm in a human’s intestine
example of a parasitic relationship	a tick on a cat
example of a parasitic relationship	mistletoe on a tree
The relationship between a Canadian lynx and a snowshoe hare is an example of	predator and prey
In which of the following relationships is neither species harmed?	commensalism
Population example that has a random dispersion	solitary snakes in a desert
This example could cause a large number of density-independent deaths in a population?	winter storms
Example of organism that has the highest reproductive potential?	bacteria
exponential growth	Within a few years a population can increase dramatically
The relationship between acacia trees and the ants that live on them is an example of	mutualism
The number of wild horses per square kilometer in a prairie is the horse populations	density
If over a long period of time, each pair of adults in a population had only two offspring and the offspring lived to reproduce, the population would	remain the same
Which of the following has the greatest effect on reproductive potential?	reproducing earlier in life
These may cause their hosts to become more vulnerable to predators.	parasites
The carrying capacity of an environment for a particular species at a particular time is determined by the	supply of the most limited resources
the growth of orchids on the high branches of tropical trees is an example of commensalism because why?	The trees are neither benefited nor harmed
A relationship in which two organisms live apart.	Symbiosis
One of the main properties used to describe a population?	number of individuals
True or False: An organism’s habitat is a location.	True
True or False: Competition for food cannot occur between animals from two different ecosystems.	True
Which of the following reproductive situations will limit a population’s biotic potential?	the maximum number of offspring each individual can produce
The difference between a predator and a parasite is that a predator usually does this to its prey	kills and eats it
The fastest rate at which a species can grow	biotic potential
The growth rate calculation	birth rate minus the death rate
The change in the size of a population over a given period of time	growth rate
Causes of deaths that occur more quickly in a crowded population	density dependent
Deaths caused by severe weather or natural disasters and not by the density of the population	density independent
This is usually described as even, clumped, or random in reference to a population.	dispersion
A robin that does not affect the tree in which it nests is an example of this	commensalism
If two species use the same food source at different times, they are considered	indirect competitors
The average age at which members of a species reproduce is called	generation time
The maximum number of offspring that each member of a population can produce is called the	reproductive potential
The three main properties used to describe a population are	size, density, dispersion
This is the maximum number of species in a population that the ecosystem can support indefinitely.	carrying capacity
The amount of food available for wolves in an area determines the ecosystem’s carrying capacity for wolves and is considered this	limiting resource
Members of a species compete indirectly for resources by competing for this factor as well as social dominance.	territory
The number of a populations members per unit area or per volume.	density
Deaths that are caused by a disease spreading through a population are	density dependent
includes that species’ physical home, the environmental factors necessary for that species’ survival, and all its interactions with other organisms.	niche
A type of interaction between two species in which both species are harmed	competition
When each species uses less of the niche than it is capable of using, in order to reduce competition for resources with other species.	niche restriction
The organisms in a cow’s stomach have a constant source of food; the organisms help the cow break down and use the grass it eats. This type of relationship is an example of	mutualism
The type of interaction between cats and mice is	predation
A liver fluke that harms its host as it obtains food is an example of a	parasite
This usually only weakens its host, while a(n) predator usually kills its prey.	parasite
A relationship in which two organisms live in close association, such as mutualism and commensalism, is called	symbiosis
If a pair of mice finds a place to live with plenty of food and no predators, the population of mice will probably undergo this type of growth	exponential
Over a long period of time, two species can develop adaptations that increase the benefit of their relationship in the process of	coevolution
When the death rate is higher than the birth rate this type of growth rate exists	negative
