What is the answer for this kind of exercise and why ?HELP
There were other researchers on the multinational expedition - a Belizean ornithologist, a British botanist, an American reptile specialist - but the mycologists had the best odds of finding a new species. The British mycologist Dr. David L. Hawksworth, extrapolating from the ratio of fungi to vascular plants (six species of fungi for every plant) in several sets of data, has estimated the existence of 1.5 million species of fungi on earth.
Fungi are neither plants nor animals; they were recognized as their own distinct kingdom only 35 years ago. In 1993, RNA research revealed that fungi are actually more closely related to animals than to plants. Mycologists still can't agree on how many species of fungi have been described - estimates range from 74,000 to 300,000
______ (2)A . "We've only discovered and named 5 to 10 percent of those," said Dr. Baroni, who is a biology professor at the State University of New York at Cortland. (About 90 percent of the world's 300,000 species of flowering plants have already been described.) . Dr. Baroni, Dr. Lodge and two other mycologists not on this trip are in the final year of a four-year survey of tropical fungi in the Caribbean and Central America. So far they've discovered more than 100 new species.
B. What ever the real figure, new species are added almost daily. Last year one journal, Mycotaxon, published descriptions of 258 new or renamed fungi. From 1980 to 1999, an average of 1,100 new species were found and described every year.
