Answer to Question 1

ANS:Answer
should include:
 Artificial classification systems are based on superficial appearances.
 Natural systems of classification are rooted in the characteristics of organisms and their
evolutionary history. Organisms can be shifted as more information is learned about a
species.
 We use a natural selection system of classification that was first developed by Linnaeus.
It is a hierarchical system that has increasing smaller groupings of organisms as a
species is categorized. There have been additional kingdoms added to Linnaeus' original
three.
 Domains have been introduced to show the largest level organisms are connected to each
other. They contain multiple kingdoms



Answer to Question 2

ANS:Answer
should include:
 Trophic levels are the feeding hierarchy of organisms. There is a transfer of energy and
nutrients in each level. Primary producers are the lowest level on the pyramid. They are
the basis of life on earth. They are able to convert light energy into a chemical energy.
 Primary consumers eat the autotrophs, the primary producers. These are also labeled as
herbivores. Each consumer level after this layer eats other consumers. Secondary
consumers eat the herbivores while top consumers are predators, carnivores.
 Each trophic level is only able to acquire 10 of the energy in the trophic level below it.
The energy can be lost through respiration and excretion.
