instruction:
In this task, you are given Wikipedia articles on a range of topics, we ask you to write a question based on the content of the articles that can be answered in a binary manner i.e. True or False.
question:
Fruit tree pollination -- Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards.
answer:
do flowers need to be pollinated to produce fruit


question:
Inflight smoking -- Inflight smoking is prohibited by almost all airlines. Smoking on domestic U.S. airliners, for instance, was banned on all domestic flights with a duration of two hours or less beginning in 1988, with all planes being smoke-free by the end of the 1990s. According to FAA regulations, smoking lit cigarettes or anything else that produces smoke or flame is prohibited onboard most commercial aircraft. As of October 2015, the USDOT prohibits the use of electronic cigarettes on flights, as well as such devices from being transported in checked luggage.
answer:
are there any smoking flights in the world


question:
Primary producers -- Primary producers convert an abiotic source of energy (e.g. light) into energy stored in organic compounds, which can be used by other organisms (e.g. heterotrophs). The primary producers can convert the energy in the light (phototroph and photoautotroph) or the energy in inorganic chemical compounds (chemolithotrophs) to build organic molecules, which is usually accumulated in the form of biomass and will be used as carbon and energy source by other organisms (e.g. heterotrophs and mixotrophs). The photoautotrophs are the main primary producers, converting the energy of the light into chemical energy through photosynthesis, ultimately building organic molecules from carbon dioxide, an inorganic carbon source. Examples of chemolithotrophs are some archaea and bacteria (unicellular organisms) that produce biomass from the oxidation of inorganic chemical compounds, these organisms are called chemoautotrophs, and are frequently found in hydrothermal vents in the deep ocean. Primary producers ares at the lowest trophic level, and are the reasons why Earth is sustainable for life to this day .
answer:

are producers the source of all the food in an ecosystem
