The movements of the sea urchins into habitats already occupied by black-lipped abalone will most likely cause

a. a decrease
b. an increase
c. no change

in the level of interspecific competition for resources. as a result of range expansion of the sea urchins, the population size of black-lipped ablone

a. could increase
b. could decrease

or both the sea urchin and black-lipped ablone
could

a. evole into a single interbreeding species.
b. evole to express more similar traits.
c. evole to use different resources.

Answer:

The movements of the sea urchins into habitats that already occupied by the black-lipped abalone will most likely cause an increase in the level of interspecific competition for resources. As a result of the range of extension of the sea urchins, the population of black-lipped abalone could decrease or both the sea urchin and black-lipped alone could evolve to use different resources.

Explanation:

Due to climate change, sea urchins are occupying an area previously inhabited by black-lipped ablone. These two organisms share similar habitats and food sources. Hence there will be competition for food resources.

Due to the range expansion of sea urchin the population of black-lipped ablone may likely to decrease as a negative effect of an increase in the population of sea urchin. To avoid this situation the organisms in the population of black-lipped ablone can shift to the other areas which is not largely inhabited by the sea urchin population.

This study was done by the researchers of  University of Tasmania on the east coast of Tasmania, Australia as it is a real-life incident happening due to global climate change.
