Q

CLASSIFICATIONS OF SPECIES INTERACTIONS

When one organism feeds on the other, rarely killing it outright; host typically survives, although its fitness is reduced.

Q

a survival tactic where a predator or parasite imitates a harmless model to avoid detection by its prey or host. The term is often compared to a wolf in sheep’s clothing.

16
Q

A competition with member of their own species

A

Intraspecific competition

17
Q

TYPE OF MORPHOLOGICAL/PHYSICAL ADAPTATIONS

reciprocal mimicry by two unpalatable species (Presumably, the more unpalatable prey there are, the faster predators learn to avoid prey with that particular appearance)

A

Mullerian mimicry

18
Q

Principle that proposes two species with identical niches cannot coexist permanently, which leads to the prediction that coexisting species will have different niches.

A

COMPETITIVE EXCLUSION

19
Q

Occurs when one organism physically restricts another organism’s access to resources including territoriality, chemical poisoning, and overgrowing.

A

Interference competition (direct)

20
Q

CLASSIFICATIONS OF SPECIES INTERACTIONS

It takes place when there is BENEFIT to one organism in the interaction without any impact on the other.

A

Commensalism (+ /0)

21
Q

TRUE of FALSE

Ecologically similar species can coexist in a community if one or more significant differences their niches arise through time.

A

True

22
Q

Occurs when two individuals that do not directly compete for resources affect each other indirectly by being prey for the same predator.

A

Apparent competition (indirect)

23
Q

An evolutionary process whereby organisms decrease direct competition by differentiating in their use of resources by altering which, how, or when resources are used.

A

Niche partitioning

24
Q

it is when species can live without their mutualistic partners

A

FACULTATIVE MUTUALISM

25
Q

CLASSIFICATIONS OF SPECIES INTERACTIONS

Like predation, it kills the host eventually.

A

Parasitoidism (+/-)

26
Q

The range of conditions under which a species can persist (grow, survive, and reproduce) and the set of biotic and abiotic resources that an organism utilizes in its environment.

A

Ecological niche

27
Q

it is when species are dependent upon the mutualistic relationship that they cannot live in its absence

A

OBLIGATE MUTUALISM
