In a fish species, the number of eggs that hatch and survive for one year varies depending on the number of eggs that were produced. As the number of eggs produced decreases past a threshold number, the survival rate of the offspring decreases. Which of the following statements best explains why only a limited number of offspring can survive in a fish population? Resource partitioning allows similar species to coexist in the same ecological community. The number of fish surviving after one year is proportional to the number of eggs produced. The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings. More yearling fish survive beyond one year when there is an abundance of prey species present.

The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings.

Female European Cuckoos lay their eggs in the nest of another bird species. Often, the imposter egg is incubated by the other birds. Upon hatching, the baby cuckoo instinctively shoves the other eggs and hatchlings from the nest. The foster parents raise the baby cuckoo which often gets much larger than the foster parents, requiring a great deal of their time and energy. This replationship is best described as: parasitism predation commensalism mutualism competition

parasitism
