Answer: B). CO₂
Cellular respiration is the process of conversion of food energy (glucose) into chemical energy (ATP). Oxygen and glucose are the reactants in the chemical reaction of this process and carbon dioxide and water are the products.
Biotic factors are the living things in any environment, while abiotic factors are the nonliving things.
So, in the Sahara desert the living things (biotic factors) would be the animals and plants.
The nonliving things (abiotic factors) would be the sunlight, temperature, dirt, etc.
Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
Answer:
it would change to 144 percent
