Review the interior layers of the Earth. Within the mantle exists the asthenosphere between about 100 km and 350 km, which is a special zone composed of hot, magma-like material that is capable of gradual flow. The energy that produces this flowable magma comes from the heat within the Earth, What is/are the source(s) of this heat energy?

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
