Population size is determined by a combination of factors that affect organismal growth, reproduction, and survival. Descriptions of some of these factors are provided below. Decide whether the effect experienced by each organism is due to density-dependent or density-independent factors. (Concept 11.2) (A) Hyposalinity (low salt concentrations) negatively affects gonadal growth and therefore the reproductive output of the stenohaline sea urchin (Paracentrotus lividus) -- (B) The COVID-19 virus spread more quickly in long-term care facilities and hospitals, increasing the likelihood of severe infection and decreasing the chance of survival for their residents (i.e., the elderly and immunocompromised individuals) -- (C) Male house sparrows (Passer domesticus) are extremely territorial and will evict all females (other than their mate) who try to use their nests by attacking them and/or destroying eggs -- (D) The death rate of the common pill bug (Armadillidium vulgare) rapidly increases above 36°C or below -2°C because it is an ectotherm (its body temperature is controlled by the temperature of its environment) --
