The giant octopus lays 20,000 to 100,000 fertilized eggs. After hatching, most octopuses become prey to larger marine organisms, and less than 5% will reach adulthood to reproduce. One benefit of the giant octopus laying many eggs is to — 

 increase the average body size for surviving individuals to avoid predation 

decrease competition between different octopus species to maintain resources in the population

 increase the chance that more individuals will survive to maintain the population

decrease the likelihood of offspring being consumed by predators

Leaf-cutter ants harvest leaves and carry them to fungi that convert plant material into a usable form for the ants to digest. The fungi depend on the leaves for nutrients. The ants also produce an antibiotic on their bodies that helps protect the fungi from harmful bacteria. Which of these explains the relationship between the leaf-cutter ants and the fungi?

Predation, because the ants feed on the fungi 

Mutualism, because both the ants and the fungi benefit from each other 

Competition, because both organisms consume the same resource for energy

Commensalism, because the ants receive energy from the fungi and the fungi are unaffected
