Breathing(CO2) of plants for making food that is eaten by animals.and expelling the carbon from animal's body by breathing or defecation
Answer:
D
Explanation:
Animals and plants preform a process known as cellular respiration.
This process is:
oxygen+glucose--> carbon dioxide+ water + ATP (energy)
If a plant was placed in this container with carbon dioxide and oxygen, it would preform cellular respiration, but it would also use another process called photosynthesis:
carbon dioxide+water+light energy-->oxygen+glucose
Since a plant performs both, the levels of carbon dioxide and oxygen wouldn't change a lot.
However, if this was an animal, the carbon dioxide levels would increase. An animal would inhale oxygen, use it in cellular respiration, and then exhale carbon dioxide as a waste product.
Therefore, the correct answer is D: increase in carbon dioxide levels.
Answer: . Estuaries rank high on the list of the most heavily impacted aquatic systems on earth. This is largely attributed to accelerating population growth and development in the coastal zone and escalating use of estuarine resources.
