Species with high fecundity, high growth rates, and small body sizes are typically
(A) Endangered species (B) Keystone species
(C) K-selected species (D) r-selected species
(A)
(B)
(C)
(D)
Endangered species are organisms whose number has reduced drastically and if not conserved will become extinct.
Keystone species are those which have an extremely high impact on a particular ecosystem relative to its population.
k-selected species have a larger body size.
Environmental instability or unpredictability favours quick reproduction and renders useless competitive adaptations in r-selected species.
Among the traits that are thought to characterize r-selection are high fecundity, high growth rates, and small body sizes.
Therefore, the correct answer is (D) r-selected species
