What is the leading contributor to the extinction rates of terrestrial and freshwater organisms?
currents, turbulence of fast-moving rivers and streams. :)
How do biologists estimate extinction rates?
Biologists estimate extinction rates in a great number of ways. One way is to document the decrease in population over time.
What is a Diversification Rates?
Rate at which new lineages/taxa originate - Changes in diversity over time - "Taxonomic Rates": diversification and extinction rates.
How does the rate of extinction today compare to the rates in the past?
they are much lower
What is mass depletions?
Mass depletion is an event in which extinction rates are higher than normal but not high enough to be classified as a mass extinction.
What is a diversification?
Rate at which new lineages/taxa originate - Changes in diversity over time - "Taxonomic Rates": diversification and extinction rates.
Why do you think extinction rates for fresh water animals are 6 times higher?
Extinction rates for fresh water animals are 6 times higher because of the changes in sea levels and currents as well as gases due to volcanic activity.
Which is the likely cause of tha current increase is rates of extinction?
AN increase in the human populations
Are there differences between major groups of organisms to how fast they respire?
Yes, respiration rates for large organisms are generally higher compared to small organisms. Large organisms require more oxygen than small organisms.
What is advantages that a sexual organisms have that helps them to overcome these disadvantages?
They have higher reproductive rates.
How we can measure dose rate from cosmic rays and from terrestrial and how do we differentiate between both the dose rates?
im not sare but my bruther loves it so i can ask him
What measures rates of decay and estimates how long and organisms been dead?
Radio carbon dating
