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 —

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?

Options: Predation, Mutualism, Competition, Commensalism

Back

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

Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?
Options:
1. Organisms at higher trophic level have less energy available to them than organism at lower trophic levels.
2. Organisms at higher trophic levels require smaller habitats that organisms at lower trophic levels.
3. Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.
4. Organisms at lower trophic levels outcompete organisms at higher trophic levels.

Back

Which human activity would most likely decrease the ability of the San Marcos salamanders to survive? Options: Increasing water consumption that decreases the flow of clean water from the springs that feed the river, Public transportation that reduces the number of automobiles that contribute to pollution runoff into the river, Tourism that helps fund the educational programs related to river ecosystem conservation, The addition of a new food source into the river that limits competition for resources.
