Explanation:
Convection can simply be described as the transfer of heat energy among molecules or substances. Convection will occur if molecules of liquid or gas are given rough supply of heat. Hot liquids or gases would have the following properties:
- Their density would be less.

Hello. You forgot to report that this question is about the "Eagle eye" article
Answer:
I had already heard about all the ecosystem services mentioned in the article and according to how the use of nature and exploitation has been taking over our society, all services receive my concern.
Explanation:
The "The Character of Ecosystem Services" section presents a series of ecosystem services that nature offers us and that are fundamental for the survival of human beings on earth. These services are: Production of Ecosystem Goods, Generation and Maintenance of Biodiversity, Climate and Life, Mitigation of Floods and Droughts, Services Supplied by Soil, Pollination, Natural Pest Control Services, Seed Dispersal, Aesthetic Beauty and Intellectual and Spiritual Stimulation.
These services are highly publicized in the media and there is no need for a long and time-consuming research to understand their importance in our lives and how we humans have failed to maintain them and caused them to be unavailable, through degrading exploitation and rampant pollution that has caused damage to nature and threatened our existence in the future. For this reason, all these services deserve our concern, in addition to deserving that all human beings change their habits to guarantee their existence and availability.
