What is an ecological niche?

Answer 23

all of the chemical, physical, and biological factors that a species needs to survive, stay healthy and reproduce

Answer 24

when two species are competing for the same resources, and one species is better suited to the niche pushing the other species out or making it extinct

Question 25

Answer 28

a close ecological relationship between two or more organisms of different species that live in direct contact with one another

Question 29

mutualism

Answer 29

An interspecies interaction in which both organisms benefit

Question 30

commensalism

Answer 30
