Question

1. Based on standard Linnaean classification, what is the taxonomy-correct scientific name for your species?
   1. Homo sapiens (sapiens)                                       d. Homo humanis humanis
   2. Homo neanderthalensis                                       e. Homo erectus
   3. All of the above (A, B, D, E)                                 f. None of the above (A, B, D, E)

2. Which of the following ecological components are NOT included within a description of a habitat’s community? (NOTE, not the same as species population or biome ecosystem)
   1. Flora                                                                         c. Microbial life
   2. Fauna                                                                        d. Abiotic factors

3. Name 2 (or more) species which are endothermic, produce milk, can develop a complete placenta, & exhibit care of their offspring.
   1. Opossum, Wolf                                                      c. Dolphin, Hippopotamus
   2. Echidna, Tiger                                                         d. Giraffe, Wallaby

4. Which of the following factors act negatively upon the overall health & genetic fitness of a particular population or group?
   1. High species density                                             d. High mortality rate                           
   2. High natality rate                                                  e. Lower carrying capacity
   3. All of the above (A, B, D, E)                                 f. None of the above (A, B, D, E)

5. A species with a long lifespan, low clutch/birth number, parental care, larger body style, & late sexual maturity is most likely to have what type of reproductive strategy?
   1. K-strategist                                                              c. R-strategist
   2. L-strategist                                                              d. D-strategist

Answer 1

1.a, Homo sapiens

' Homo' is the genus and ' sapiens' is the species name of human. Carl Linnaeus classify human in this way.

​​​​​​2. d, Abiotic factors

Communities do not include abiotic factors but only include the biotic features in a region such as, flora, fauna, microbes etc.

3.b, Echidna, Tiger

c, Dolphin, Hippopotamus

Opposum and wallaby are marsupials, so they do not have a fully developed placenta. Others are endothermic with a complete placenta, produce milk and show parental cares.

4. d, High mortality rate

High species diversity and Natality rates are positively affect population. Below the carrying capacity, populations typically increase. Hence, the mortality rate affect population negatively. I.e, the mortality rate reduces the overall fitness of a population.
