Aquatic and marine dead zones can be caused by increases in nitrogen and phosphorus in the water from human waste or fertilizer. these substances encourage algal blooms. although algae produce oxygen in the daytime by photosynthesis, during the night hours they continue to undergo cellular respiration and use up available oxygen. when algal blooms die off, more oxygen is used during decomposition of the dead algal cells. both of these processes can result in a significant depletion of dissolved oxygen in the water, creating dead zones. dead zones can be caused by natural or human factors. a. summarize the role of algal blooms in disrupting the health of aquatic ecosystems.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
