Vedclass · Answer

(D) Species are more susceptible to extinction due to several ecological and biological factors. $1$. Large body size: Large animals often require more resources and have lower reproductive rates,making them vulnerable. $2$. Small population: Small populations have low genetic diversity and are highly susceptible to environmental fluctuations and stochastic events. $3$. High trophic level: Organisms at higher trophic levels (like top predators) are vulnerable due to biomagnification of toxins and dependence on a large prey base. Therefore,all these factors contribute to the risk of extinction.
