Q

relationship between species diversity and complexity of an ecosystem

A

the higher the species diversity of a community/ecosystem, the greater the complexity.

higher survival rate because the alleles that exist will help the species against any issue in the enviornment

Q

define habitat diversity

A

the range of different habitats in an ecosystem or biome. conservation of habitat diversity usually leads to the conservation of species and genetic diverstiy

Q

why is quantification of biodiversity important?

A

Its important to conservation efforts so that areas of high biodiversity may be identified, explored, and appropriate conservation put in place where possible

Q

usefullness of providing numerical values of species diversity to understanding the biological communities and the conservation of biodiversity

A
  • comparison is possible
  • essential in identifying areas that should be protected against damaging human activity
