Biodiversity Terrestrial biodiversity is up to 25 times greater than ocean biodiversity. Although a recent discovered method put the total number of species on Earth at 8.7 million of which 2.1 million were estimated to live in the ocean, however this estimate seems to under-represent diversity of microorganisms.

How many types of animals are there in the World? The number of known species for all animals other than arthropods is about 250,000. The largest group within the phyla of arthropods and the most diverse class in all kingdoms, is insects.

The Five Kingdoms Of Life There are more than one million species of animals (Kingdom Animalia), more than all the other kingdoms combined. More than half of all animal species are insects (800,000 species), and beetles (300,000 species) comprise the largest order of insects (one fifth of all species--using a total of 1.5 million).here are more than one million species of animals (Kingdom Animalia), more than all the other kingdoms combined.

#63: How Many Species Inhabit the Earth?â© Last year researchers at Dalhousie University in Nova Scotia released the most rigorous estimate yet of how many species live on our planet: 8.7 million, not counting bacteria. Nearly 6.5 million of these species live on land versus 2.2 million in the ocean, according to the analysis. “Humanity has committed itself to saving species from extinction, but until now we have not had a good idea of even how many there are,” says coauthor Boris Worm, a marine ecologist at Dalhousie. Previous estimates have ranged from as few as 3 million species to as many as 100 million. To arrive at a more certain answer, marine ecologist Camilo Mora examined life’s diversity at higher levels of taxonomy (genus, family, order, et cetera).

Number of Species Identified on Earth Mammals make up one of the smallest groups, with just 5,513 members. Altogether the earth's oceans, lakes, continents and islands support over 66,000 identified species of vertebrate animals and more than 307,000 species of plants.

UN Environment Programme: 200 Species Extinct Every Day, Unlike Anything Since Dinosaurs Disappeared 65 Million Years Ago UN Environment Programme: 200 Species Extinct Every Day, Unlike Anything Since Dinosaurs Disappeared 65 Million Years Ago. According to the UN Environment Programme, the Earth is in the midst of a mass extinction of life. Scientists estimate that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours. This is nearly 1,000 times the natural or background rate and, say many biologists, is greater than anything the world has experienced since the vanishing of the dinosaurs nearly 65m years ago.

- The document proposes a working estimate of 13.6 million species on Earth. But some field scientists, such as Erwin, dismiss this as armchair biology.. Of course, the only way to really find out how many species inhabit the planet is to go out and count them, one by one. Spurred by concern over species extinctions, several scientists over the past decade have advocated such a complete global biological survey.

Earth is on brink of a sixth mass extinction, scientists say, and itâs humansâ fault The losses of the past century account for only about 1 percent of the roughly 40,000 known vertebrate species — a statistic that pales in comparison to the level of destruction seen during previous mass extinction events. Even in the least of them, between 60 and 70 percent of species were killed off.

Total Number of Species Estimated in the World Over seven million species of plants and animals live on planet earth, according to the best estimates made by biologists. If you add in the world's species that aren't plants or animals, such as lichens, mushrooms and bacteria, the total number of species leaps much higher. Tallying the estimates of all living things brings the number to 11.3 million species currently on earth.

How Many Species? A Study Says 8.7 Million, but Itâs Tricky Scientists have named and cataloged 1.3 million species. How many more species there are left to discover is a question that has hovered like a cloud over the heads of taxonomists for two centuries.ut critics say that the method in the new paper can’t work, and that Earth ’s true diversity is far greater. In 1833, a British entomologist named John Obadiah Westwood made the earliest known estimate of global biodiversity by guessing how many insect species there are.

Viral disease As a general rule, DNA viruses replicate within the nucleus while RNA viruses replicate within the cytoplasm. Exceptions are known to this rule: Poxviruses (DNA viruses) replicate within the cytoplasm and orthomyxoviruses and hepatitis D virus (RNA viruses) replicate within the nucleus.

7 Continents of the World Planet Earth is home to 7.2 billion people and over 1.5 million different species of animals, insects, and plants spread across 7 continents. Earth was not always comprised on seven continents. 175 million years ago the 7 continents were all connected into one supercontinent surrounded by a very large ocean.

- So let's say there are 17 million species on earth, just to plot it right in the middle. 200 species per day = 73000 species per year. So if there are 17 million species on earth, and we lose 73000 whole species per year, that means in 232.8 years there not be a single living organism on earth.No animals, plants, humans, fungus, NOTHING in 232.8 years.Earth will just be a bald, powdery rock in 232 years, just like the Moon.o if there are 17 million species on earth, and we lose 73000 whole species per year, that means in 232.8 years there not be a single living organism on earth.

86 Percent of Earth's Species Still Unknown? By contrast, the number of newly discovered species continues to rise sharply. Using complex statistics, Worm and colleagues used the number of genera, families, and so on to predict Earth's number of unknown species, and their calculations gave them a number: 8.7 million.

Species count put at 8.7 million The approach accurately predicted the number of species in several well-studied groups such as mammals, fishes and birds, providing confidence in the method.. And the number came out as 8.7 million - plus or minus about a million.

How Many Species? A Study Says 8.7 Million, but Itâs Tricky “It’s astounding that we don’t know the most basic thing about life,” said Boris Worm, a marine biologist at Dalhousie University in Nova Scotia. On Tuesday, Dr. Worm, Dr. Mora and their colleagues presented the latest estimate of how many species there are, based on a new method they have developed. They estimate there are 8.7 million species on the planet, plus or minus 1.3 million.
