Tricky question...
Scientists have described and given scientific names to about 920,000 species of insects in the world, which is impressive since mammals (of which humans are one) only have approximately 4,000 known species.
As for your actual question...
It is estimated that there are 20-30 million species of insects on the earth at present. In a good year, taxonomists throughout the world describe and name about 2,000 species of insects.

There are about 240 different species of shrews, and more are discovered every year.
It differs from species to species. Some frog species lay tens of thousands each year, while others may lay just a few hundred.
There are only 9 million turtles in the world. Keep turtles alive!!!
Too many to count.
25,077,985
The Mississippi River has an unkown amount of species living in it because there are many found every year
In the Amazon Rainforest alone, 1 species becomes extinct every 15 seconds!

NONE. New species may be found each year but not created unless in a lab.
35,150 animals become extinct every year.
The taiga doesn't have as many plant and animal species as the tropical or the deciduous forest biomes. It does have millions of insects in the summertime. Birds migrate there every year to nest and feed.
As scientists are discovering a new species of gecko almost every year, there are around 1500 different species of geckos.
Yes, it is almost true if there is not much variation in climatic conditions.
As of this year, there are over 28,000 species of fish. However, new species of fish are being discovered every year and this number is constantly increasing.
The number of new species discovered by scientists in a single year can range from a few hundred to ten of thousands. With the number of species of plants and animals in the world estimated in the hundreds of millions, finding new species is relatively easy.
