Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient.
Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Facilitated diffusion is a form of passive transport, in Facilitated diffusion molecules move across a semi-permeable membrane with the aid of specialized transports proteins and in active transport molecules move across the plasma membrane with the expenditure of ATP.
The difference between primary and secondary transport is whether the transporter directly or indirectly uses energy Primary active transport: ATP is used directly, and the energy comes from the breakage of a high energy phosphate bond. Secondary active transport: ATP is not used directly, and the energy comes from a gradient that was created by a primary active transport system that used ATP.
Primary active transport directly uses ATP by hydrolysis
Secondary transport uses an electrochemical gradient across a membrane initiated by primary active transport.
Primary active transport is the process in which ions are moved across cell membranes against the electrochemical gradient using energy supplied directly be ATP. The action of the sodium-potassium pump is an important example of primary active transport.
Secondary active transport is indirectly driven by primary transport. In the sodium-potassium pump, by pumping against the gradient, energy is stored in the ion gradient. Then, just as water pumped uphill can do the work as it flows back down, (think water wheel or turbine), a substance pumped across the membrane can do work as it leaks back, propelled downhill along the concentration gradient.
1\ In primary active process:
It required energy (ATP) to move the solute up the concentration gradient.
***
2\ In secondary active process:
It required no energy.. But instead, it needs:
primary is found fomr the ground
secondary has been nroinfoisjnfpe;mf
Movement of a substance that utilizes a carrier, and has a concentration gradient as the source of energy.
The primary difference is that in active transport, energy is used.

facilitated diffusion, secondary active transport and active transport
Yes, any form of active transport uses energy.
Secondary active transport aka facilitated diffusion [depending on your teacher].
yes
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated

secondary active transport
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
