Look at an ocean system below. Phytoplankton
produce half of
the world's oxygen
Shrimp feed on
plankton and also
need oxygen to live.
Salmon feed on
shrimp and need
oxygen to live
People often eat
salmon. We also
need to breathe
oxygen to live
What would most likely happen if the number of shrimp decreased?
A. The plankton population would not change.
B. The salmon population would increase.
O C. The plankton population would increase.
D. The salmon population would not change.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
