Which factors may contribute to the extinction of a species? Check all that apply.

a more individuals fighting over the same resources
b fewer individuals fighting over the same resources
c the loss of the environment in which an organism’s needs are met
d the gain of an environment in which an organism’s needs are met
e the lack of predators in an area
f the introduction of new predators into an area

A. More individuals fighting over the same resources

This means there's not enough resources to sustain the population.

C. The loss of the environment in which an organism’s needs are met

This means that the population no longer has a habitat that it can live in, and as the species tries to adjust to it's new environment, it gets killed off.

F. The introduction of new predators into an area

Because it's new, the population doesn't know how to respond to this new threat, and therefore is easy prey.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
