role of species within its habitat

Question 7

Question 8

biotic

Answer 8

the living features of an ecosystem

Question 9

carrying capacity

Answer 9

maximum stable population size that an ecosystem can support

Answer 10

between different species
the more similar the niches the more competition

Question 11

intraspecific

Answer 11

within a species. animals often have their own territory to reduce this competition. usually there is competition for a mate

Question 12

predator prey population curves

Answer 12

population sizes are interlinked

Question 13

why are predator prey relationships more complex

Answer 13

this is because there may be intraspecific competition in the prey for eg space or food so limiting prey population sizes even if predator numbers arent high
