Will mark brainliest if it's a farmer grows corn on his farm year after year, without a break. what will most likely happen on this farm? a) the soil will slowly be washed away. b) the farmer will not need fertilizer to grow corn. c) the soil will have no nutrients to grow the corn. d) the amount of corn harvested will increase every year. scientists have been genetically modifying food crops since the mid 1990's. as a result, scientists have been able to produce crops that are more disease resistant. what could be seen as a risk associated with using genetically modified crops? a) reduction in nutritional value of the food crop b) plants can be "tailor made" for the desired trait c) crops may cause an increase of allergic reactions in humans d) crop production would be increased due to greater disease resistance the majority of earth's atmosphere is nitrogen, n2. the percentage of nitrogen in earth's atmosphere remains constant as prescribed by the law of conservation of matter and because it is a reasonably non-reactive gas. like carbon, nitrogen is cycled through earth's spheres. however, nitrogen can be converted into forms usable by plants and animals, either by lightning or bacteria. once converted to usable forms, nitrogen is able to cycle the rest of the way through the ecosystem. much like carbon, the recycling of nitrogen through earth's spheres relies heavily on what type of organism? a) autotrophs b) decomposers c) parasites d) producers
