- What is often true of a population of organisms with a type Il suvivorship curve? they produce few offspirng and invest more energy in each offspring they produce more offspring and invest little energy in each they have low death rates during early life stages they are equally likely to die at any ageSpecies A is present in a community. Species B is introduced to the community. Over the next year, the population sizes of both continual decrease from initial numbers. Which one of the following community interactions might be the cause of this decline? Interspecific competition O Intraspecific competition O Mutualism O Parasitism O PredationAssuming that a population is not near the carrying capacity of its environment, what is likely to occur if the number of pre-reproductive and reproductive members of a population is greater than the number of postreproductive members? Othe population density will increase the population growth rate will decrease Cthe population will remain at the same density
