Which of the following is a biotic factors in an ecosystem? O sunlight O nutrients in soil and water O precipitation O microorganisms

microorganisms

Explanation:

Biotic factors include fungi,algae,bacteria etc.

While, Abiotic factors include soil, water ,sunlight and minerals

Explanation:

A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.

An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.

Let's examine our answer choices.

Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.

That leaves: microorganisms. Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
