I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
The water cycle is also referred to as the hydrologic cycle.
Answer:
The process that is used by producers to make glucose is called photosyntheis and the chemical process used by both producers ans consumers to make ATP ito contribute to the energy exchange is called cellular respiration.
Explanation:
Photosynthsis
Photosynthesis occue in the mesophyll tissue present in leaves of plants .During photosynthesis the green plants or producers acquires CO2 from the atmosphere and utilizes water in presence of sunlight to produce glucose molecules along with the liberation of oxygen gas.
Cellular respiration
During cellular respiration the glucose molecules are oxidized to form energy in form of ATP along with the production of water and carbon dioxide.
The O2 that formed during photosynthesis is inhaled by human beings for respiration whereas the CO2 that is produced as waste material inside our body is exhaled by us in the atmosphere.The CO2 is then used by the green plants to carry out photosynthesis.
Muscular tissues or cells expand and contract to move the body
