Answer:

3.5 billion years ago, or in the Eoarchean Era.

Explanation:

The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era.

Who would the double pour technique be a preferred method of fabricating a cast/study model
vodomira [7]

Prevents distortion

Double-pouring technique is used for casting, it prevents distortion of the material to be fabricated or the study model.

It ensures the study or fabricated model is firmly withheld, increasing the material life span, and can be used at extreme conditions.

How is the law of conservation of mass applied to ecology?
Thepotemich [5.8K]

In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.

<h3>What is the law of conservation of mass?</h3>

The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.

In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.  

Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.
