What animal has the highest population on Earth?
== == There can be a million tons of krill in a singel swarm. Krill are considered keystone species near the bottom of the food chain because they feed on phytoplankton and to a lesser extent zooplankton. The number of plankton EASILY outnumbers all other animals on the earth - unless you get into bacteria. Plankton are found in every part of every ocean - and whales often eat millions of them in a single day!!! Hard to see anything more popular than plankton!! "Plankton are tiny open-water plants, animals or bacteria. The name, like the word planet, is derived from a Greek root that means, "wanderer." These organisms range in size from microscopic bacteria and plants to larger animals, such as jellyfish. Plankton generally have limited or no swimming ability and are transported through the water by currents and tides."
There are several major population center on the Earth. It can be said that nations located in the temperate zones have the highest populations. It appears that most of China is in this zone. Based on China's huge population combined with nations like Japan, the US and Europe this seems quite correct.
The mammal group with the highest population is the mouse. With an estimated 30 per every human on earth, that means there are approximately 210 billion mice on the planet. The single mammal species with the highest population would be Humans. Cows number approximately 1.3 billion. Dogs number 500 million, cats number 300 million. In short, the animals whose specie has the highest numbers are the ones with the most importance to humans. Outside of…
There are about 7 billion people on Earth but the locations with populations above 1 million that have the highest density of population include countries and regions like Singapore with 7301 people per square kilometer, Hong Kong with 6396 people per square kilometer and Bahrain with 1646 people per square kilometer.
