Which of the following describes the effect of global climate change on biodiversity: Rising ocean water temperatures have increased the populations of krill and Antarctic silverfish thus increasing Adelie penguin populations for whom these are food sources. Warm temperatures and more frequent dry periods have stressed frog species such as the coqui making them more vulnerable to a lethal fungal infection thus reducing their populations. The warming of ocean waters in conjunction with increased carbon dioxide dissolving into ocean has resulted in boon for coral reefs which are thriving. Mountain ecosystems are not too vulnerable to global climate change because only very hardy species live at high altitude.

Warm temperatures and more frequent dry periods have stressed frog species such as the coqui making them more vulnerable to a lethal fungal infection thus reducing their populations.

Explanation:

Rise in temperature, flooding as well as drought affect biodiversity. As climate changes, there is usually an alteration of temperature as well as weather patterns, the impact is felt by

plant and animal life. According to

Scientists, there is an expectation that

number and range of species, which are regarded as biodiversity will experience declination with greatly increase in temperatures

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
