According to the data above, humans exhibit a high chance of surviving into old age.
Rom4ik [11]

Based on the data provided, we can conclude that the graph in question corresponds to the K-selected theory in regards to the human species.

When considering the data of certain species and grouping them into categories such as extinct, endangered, or K/r-selected we take into account factors such as:

  • Population size
  • Behavior
  • Carrying capacity
  • Reproduction rates

and so on, then classify each species accordingly.

Species that are Extinct are no longer on the earth. This classification refers to species of the past and does not include humans as of yet. The endangered category is reserved for species whose population sizes are <u>at a critical low and are near </u><u>extinction</u>, which is also not the case for humans.

The K-selected and r-selected theories consider reproduction rates and carrying capacity as well when grouping species. Species that produce few offspring at a time are often found in this group. This category also refers to species whose offspring have a high chance of survival into maturity and whose population size is near the limit of the environment. All of this follows the data given and is the classification for the human species.

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.

Changes in these bases can bring about mutations that are beneficial) of organism and also it depends on where in the genetic code they occur. Beneficiary mutations can bring about increased fitness of the organisms involved.
