Answer:
In thermodynamics, a closed system can be described as a system which can exchange energy from outside but matter cannot be transferred from such a system. This means that the resources present on the Earth cannot be transferred or replaced and the waste can also not be removed. By understanding the concept of the closed system, humans should recognize the fact that many resources such as minerals present on the Earth cannot be replaced and hence, resources should be utilized effectively in a conserved manner. Also, as waste cannot be removed hence humans should stop forming such waste products which cannot be removed or recycled.
Ecosystem services are the benefits to people from nature. These benefits include food, water purification, carbon sequestration, soil stabilization, recreation, cultural values, among others.
The world's ecosystems are necessary capital assets due to the ecosystem services and the biodiversity they provide.

<u>Substituion mutation</u> is responsible for small changes in a trait.
Explanation:
This kind of mutation merely changes the type of nucleotide in the DNA sequence. The mutation does not cause a frameshift as would a deletion of addition mutation.
A substitution mutation would at worst change an amino acid in the translated protein. This would likely have a slight effect on how the protein folds into an active protein. On the other hand, mutations that cause frameshifts have the biggest effect on the proteins. They change all the amino acids of a protein downstream of the point of mutation.
