<span>1. </span>Describe how energy and matter move through the environment under <span>
A. Aerobic conditions -Photosynthesis and Respiration
-After photosynthesis occurs, the plant enters the carbon cycle. The carbon cycle uses the by-product of photosynthesis which is carbon dioxide. Carbon dioxide combined with water yields glucose (used as food) and oxygen that is released back into the atmosphere. During photosynthesis, respiration occurs which uses the oxygen and glucose to yield carbon dioxide and water which starts the carbon cycle.
B. Anaerobic conditions Muscle respiration
-This process does not require the use of oxygen.
Glucose stored in the body is used during muscle respiration to produce lactic acid and energy that is used for movement. </span>
<span>2. </span><span> What is chemosynthesis?</span><span>
<span>- Chemosynthesis relies on chemical reactions to produce food. Inorganic compounds such as hydrogen sulfide, carbon dioxide, and oxygen enter into a chemical reaction that yields sugar, sulfur, and water, Chemosynthesis occurs most commonly in deep-sea ecosystems where the sun cannot penetrate. </span></span>
<span>3. </span>How do chemosynthetic organisms get energy?
<span>- </span><span>Chemosynthetic organisms make use of chemicals found on the seafloor or on the sea environment. They convert these chemicals through a reaction that yields glucose (which the plants use for food) and sulfur as by-products. In turn, other organisms will use the sulfur by-product to initiate another chemosynthetic reaction to create food.</span>
Answer:
A) photorespiration.
Explanation:
Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.
The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate.
The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.
The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.
Thus, Option-A is correct.
The speed of light in a vacuum is <span>299,792,458 meters/sec, or approximately 300,000 meters/second.
