Explanation:
Photosynthesis is the process by which green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
It is expressed using the equation below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
reactants products
1. Compounds consumed are carbon dioxide and water.
2. Product is glucose and oxygen.
3. Most organism obtain their nourishment directly and indirectly from photosynthetic activities.
Plants are the producers of food in the ecosystem. If the process of photosynthesis does not occur, there is no way other organisms will obtain their own nourishment.
Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3).
Answer:
Explanation:
A cold front is a transition zone from warm air masses to cold air masses. We use weather elements to identify cold fronts.
- Temperature: Since air moves from warm masses to cold masses, the air in a cold front is at different temperatures. The air behind a cold front is warm while the one ahead is cold. This implies that within a cold front is at different temperatures.
- Precipitation: Prior to the passing of cold front, precipitation is usually rife with low showers. A coldfront in itself is usually accompanied by heavy rainfall full of thunderstorms and lightening. After a coldfront, the showers steadies and decreases.
- Pressure changes: before a coldfront, the atmospheric pressure decreases steadily. When the front arrives, the pressure further lowers with a sharp increase thereafter. After the front, the pressure can continue to increase.
