Answer:
ecological succession.
Explanation:
The plant may not be present in 25-50 years due to ecological succession. in ecological succession, the vegetation such as small plants that is present replaces by the more suitable vegetation such as trees because the vegetation (small plants) did not receive nutrients and sunlight so they are unable to grow and finally dies due to lack of basic needs. So that's why plant may not be present 25-50 years.
Answer:
4) molecule, cell, organ system, population, ecosystem, biosphere
Explanation:
Various biomolecules such as carbohydrates, proteins, lipids, etc. together make the cells. Cells are the structural and functional units of life. A group of cells destined to perform specific functions makes tissues and various specific tissues together make an organ.
An organized group of tissues and organs that work cooperatively to perform a specialized set of functions is called an organ system. For example, the digestive system includes organs involved in the breakdown of nutrients.
A group of organisms of the same species that live in a defined geographic area at the same time make a population. Ecosystem refers to an interacting system including a biotic community and its nonliving, physical environment. The biosphere includes all of the parts of Earth where life forms exist and include the atmosphere, the hydrosphere and the lithosphere.

2.Las condiciones ambientales en ergonomía tienen que ver con el diseño de aspectos como la temperatura, la iluminación o el ruido. En centros de atención a personas dependientes los principales problemas se relacionan con la temperatura y la iluminación y afectan a casi todos los trabajadores
3.SUSTANCIAS ORGÁNICAS E INORGÁNICAS Las sustancias orgánicas son todas aquellas relacionadas con la vida, y se componen de carbono, de oxígeno o hidrógeno, mientras que las inorgánicas son sustancias "muertas", donde escasean estos elementos propios de la vida como el carbono, el oxígeno y el hidrógeno, o si
