- If decomposers were removed from an ecosystem, which of the scenarios below would occur? A. The number of plant species would increase due to the increased space available. B. The number of animals would decrease due to the lack of plant life. C. The ecosystem would collapse due to the lack of nitrogen and carbon available to producers.arrow_forwardNitrogen availability is a limiting factor in crop production. * D. Disagree, because atmospheric nitrogen is about 80% and therefore nitrogen is readily available. A. Agree, because almost 80% of the atmospheric nitrogen (N2) is readily available. C. Agree, because atmospheric nitrogen must first be reduced to ammonia through N-fixation. B. Disagree, because only a small fraction of the atmosphere is composed of nitrogen gas.arrow_forwardMichael wants to build a new storage shed and is considering clearing some trees from his land to use as lumber.
