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.

Answer:
Axons with high diameter, and myelinated will conduct action potential faster.
Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission
Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.
Axons with low diameter, and unmyelinated will conduct action potential slowly .
Explanation:
Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.
Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1
.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
