Answer:
The correct answer is D. an unbalanced force.
Explanation:
If an unbalanced force were applied to the glass of water (for example, someone pushing the glass, lifting it up, etc.), this would cause it to move. However, a balanced force (if two people were to simultaneously pull the glass in opposite directions with the same amount of force) would not cause the glass to move. Gravitational force acts on all objects; the force due to gravity is already acting on the cup at rest and will not cause it to undergo motion. Friction is also already acting on the cup in the form of static friction, making it harder for someone to move the cup, so frictional force will not cause the cup to move either. Therefore, the correct answer is D. an unbalanced force.

Answer:
Glucose is the substance produced during photosynthesis which provides food for plants and animals in a food web.
Explanation:
The main source of energy in a food chain or food web is made by the producers. These producers are mostly plants that make food by the process of photosynthesis. As a result of photosynthesis, glucose is made as the main product whereas oxygen is made as the by-product. Glucose made is used to drive energy for all the activities of the cell. This energy, released from glucose, is carried within an ecosystem from one organism to another.
