Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.

[14] considering the food web, which trophic levels would be impacted by lower yields of fungi (mushrooms) due to, for example,
LekaFEV [45]

A reduction in number of fungi in the food web lead to a decrease in the producers and the other consumers.

  • Trophic levels are hierarchies in an ecosystem. The trophic level of an organism is the position in the food chain. A trophic level can be defined as a group of organisms in the same level in a food chain or food web.
  • Organisms are organized into various trophic levels. They can either be producers, consumers or decomposers. Decomposers include bacteria and fungi that feed on dead organic matter.
  • If fungi were to  affect by acid rain that will lead to low yields and then  there would be few decomposers in the food web and hence there would be no recycling of nutrients in the food web.
  • Fungi help to remove the environment of the dead organic organisms and add nutrients to the soil for use by the primary producers.
