Look carefully at the model. plants take in and release carbon dioxide. plants take in carbon dioxide for photosynthesis. what process releases carbon dioxide back into the atmosphere?

The correct answer would be cellular respiration.

Cellular respiration refers to the set of biochemical reactions take place in an organism which helps in the production of energy in the form of ATP (adenosine triphosphate).

It harnesses the chemical energy present in the food (glucose mainly) and converts it into the energy currency of the cell, that is, ATP.

Carbohydrate and oxygen are the substrate of cellular respiration and carbon dioxide, water, and energy (ATP) are the products.

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP

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
