Energy is a fundamental component in an ecosystem and is contributed by the primary producers. how can light energy, in turn, support the consumers of an ecosystem? a. light energy is converted to chemical energy by primary producers and primary consumers. consumers belonging to higher trophic levels feed on them to gain energy. b. primary producers can only obtain energy from sunlight by photosynthesis and gain energy by feeding on them or other consumers which have consumed these producers. c. primary producers convert light energy to chemical energy using photosynthesis and consumers gain energy by feeding on them or on other consumers that have consumed these producers. d. primary producers convert light energy through chemosynthesis and consumers gain energy by feeding on them or other consumers which have consumed these producers.

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.
