What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Gnoma [55]

Answer:

The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".

Explanation:

In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

NEED HELP ASAP: List two ways in which the atmosphere would be impacted in the absence of the biosphere. Use complete sentences.
julia-pushkina [17]

Answer:

If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.

There would be no  negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.

Hope it help!

Skin cells form new cells in<br> Mitosis only<br> O Meiosis only<br> Both<br> Neither
Fiesta28 [93]

Answer:

Mitosis only

Explanation:

Mitosis and meiosis are both types of cell division. Mitosis allows cells to proliferate for growth and repair. So this is how skin cells form new cells.

Meiosis is a type of cell division specific to reproduction. It forms the gametes, which are the egg and sperm. It generates haploid cells that fuse via fertilization to create a zygote.
