How much weight do humans add to the Earth?
Since then, anthropogenic mass has grown exponentially to approximately 1.1 trillion tons today. It’s now accumulating at a rate of 30 billion tons a year, which corresponds to each person on Earth generating more than his or her own weight in manufactured stuff every week.
What makes the most biomass?
The total global biomass has been estimated at about 550 billion tonnes C. Most of this biomass is found on land, with only 5 to 10 billion tonnes C found in the oceans….Global biomass.

What percentage of life on Earth is human?
0.01%
Humans comprise a very small share of life on Earth — 0.01% of the total, and 2.5% of animal biomass [animal biomass is shown in the right-hand box on the visualization above].
Do bugs outweigh humans?
All life on Earth, in one chart As you can see, plants dominate our world. And if we zoom in on all animal life, we again see how insignificant humans are compared to everyone else in the kingdom. Arthropods (insects) outweigh us by a factor of 17. Even the mollusks (think clams) weigh more.

Who has the greatest biomass in a food chain?
the producers
The trophic level that contains the greatest biomass in most ecosystems is the producers.
What organisms have the least biomass which has the least energy?
The trophic level that has the least biomass is usually the tertiary consumers.
What is the most common living thing on earth?
Pelagibacter ubique is often cited as the most common organism ever: it’s a third of all the single-celled organisms in the ocean.
How do we live on Earth?
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
