3.7.4 Populations in ecosystems

Question 1

what is a community

Answer 1

all the populations off different species living in the same habitat at the same time

Question 2

what is an ecosystem

Answer 2

a community and the abiotic components of its environment

Question 3

what is a niche

Answer 3

the specific role of a species within its habitat governed by its adaptation to both abiotic and biotic factors

Question 4

explain the advantages of having a niche

Answer 4

less competition for food or resources
as two species in the same niche, one would outcompete the other

Question 5

what is carrying capacity

Answer 5

the maximum stable population size of a species that an ecosystem can support

Question 6

factors that effect carrying capacity

Answer 6

abiotic factors like light intensity, temp. soil ph, mineral content and humidity
interspecific competition (different species e in inter and e in different )
intraspecific competition ( same species, a in same and a in intra )
predation

Question 7

explain how interspecific competition may effect population size (e different )

Answer 7

reduces resource (named) available to both species limiting their chance of survival & reproduction. Population size of both species reduces
better adapted species will outcompete the other, less well adapted species population side decrease
