Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.
Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium.

Answer:
a .carbon dioxide(Co2) and water (H2O)
b. air and soil
Explanation:
