<span>Motility: Mechanical breakdown and mixing of ingested nutrients by smooth muscle movements, passage of nutrients through the digestive tract, and elimination of undigested or unabsorbed residues from the body.</span><span>Secretion: Release of enzymes, hormones, and other substances that take part in digestion.</span><span>Digestion: Chemical reduction of ingested nutrients into particles, then into molecules small enough to cross the lining of the gut and reach the internal environment of the body.</span><span>Absorption: Passage of digested nutrients from the gut lumen into the blood or lymph, which distributes them throughout the body.</span>
Answer:
Interactions between biotic and abiotic components regulate carbon dioxide and water levels.
Explanation:
Abiotic factors include temperature, water, humidity, etc; while biotic factors include all the forms of life. These factors interact in the ecosystem to maintain its homeostasis. For example, during the photosynthesis, plants use the energy of the sun water and carbon dioxide to produce food (carbohydrates) and this process converts carbon dioxide (CO2) to oxygen, which is critical for maintaining the homeostasis of the ecosystem.

Answer:
At dusk or C
Explanation:
Plants produce oxygen when they make energy for themselves via photosynthesis so the more oxygen it is making, the more photosynthesis it is doing.
Answer:
D. Groundwater depletion
Explanation:
Groundwater is the water that is found just under the surface of the earth.
The effect of using groundwater to irrigate crops between 1955 and 1977 in the San Joaquin Valley was that there was groundwater depletion as there was scarcity of groundwater, even as the irrigation brought increase in yield.
