I would choose the mountain ecosystem.
The mountain ecosystem contains a complex living organisms.
Mountain lands support a diverse array of habitats with large range of plants
and animals. It is very crucial for biological diversity and is very wonderful
to see. The climate is mostly cool which is fitting for relaxation.
In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
No because it does not use energy, reproduce, have a metabolism, breathe, or maintain homeostasis and its not made up of cells.
Because ocean acidification could affect the marine species negatively therefore altering marine life and biodiversity it affects humans as well, many people from all over the world depend on food that comes from the ocean we need these food for protein.
Hey! I'm pretty sure this is chemistry instead of biology haha
But anyways, a typical carbon atom can form up to 4 covalent bonds!
