12 population interactions

Question 1

Population Interactions

Answer 1

*interactions within species populations (intraspecific) and
between different species in a community (interspecific)

Question 2

what is COMPETITION

Answer 2

In competition each population adversely affects the
other in a struggle for limited resources such as space, food.
Competition may be intraspecific or intraspecific, Less severe interspecific competition results in intraspecific. competitioncan result in adjustments that one species replacing another, forcing it to occupy another space or food source. Closely related organisms are not in the same places, use different sources of food, are active at different times, or otherwise occupy different niches. Competition may be indirect.

Question 3

what is PREDATION

Answer 3

the predatorkills and eats another individual, is an interspecific relationship. natural selection tends to reduce or even eliminate the detrimental effects of predation

Question 4

what is PARASITISM

Answer 4

the parasite benefits from the host harming it in the process. there are ectoparasite and endoparasite. parasite-
mediated competition influence the competitive interaction between two species.

Question 5

what is ANTIBIOSIS

Answer 5

one population produces a substance that is harmful to a
competing population

Question 6

what is COMMENSALISM

Answer 6

one population benefits, but the other is unaffected, Many commensals are not specific to one host(oysters and crab)

Question 7

what is PROTOCOOPERATION

Answer 7

organisms gain by an association, but relations are not obligatory.(crabs and coelenterates)

Question 8

what is MUTUALISM

Answer 8

individuals involved in the interaction benefit from the relationship(The termite-intestinal flagellate partnership)
(nitrogen-fixing bacteria and legumes)

Question 9

wha is AGGREGATION

Answer 9

sub-grouping of individuals in a population. in plants is inversely
related to the mobility of seeds, spores
group survival: withstand wind, poison, and temperatures than isolated
Termites, ants and bees, have the most highly developed
insect societies with a division of labor by reproductive
(queens and kings), workers, and soldiers.

Question 10

what is Territoriality

Answer 10

Individuals, pairs, or family groups within populations
usually limit their activities to a defined area, called the home
range. When this area is actively defended, it is called a
territory
Most territorial behavior involves a minimum of actual fighting over boundaries,
Some species populations alternate between territoriality and aggregation
