Which factor impacting the marine environment is considered biotic?

decreased physical space
increased predation
increased water temperature
decreased salt concentration

Increased predation

Explanation:

A biotic factor can be define as a living being of the ecosystem which interacts with the non-living physical environment. Predation is an ecological interaction among the distinct species in an ecosystem. In this one organism kills the other in order to obtain it as food. The organism which is killed is called as prey.

The increased predation can be considered as biotic because of the fact that it involves the interaction of the living beings in the marine environment.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
