Evaporation and Transpiration

Answer:
Major difference between active transport and facilitated difusion is:
Active transport moves substances against the concentration gradient.
Facilitated diffusion moves molecules through the plasma membrane.
Explanation:
- Active transport involves the transport of molecules against the concentration gradient.
- Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
- Facilitated diffusion do not require energy but need some other molecule or carrier protein to transport the molecules across the membranes.
- In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.

Yes
Explanation:
An energy pyramid shows the amount of available at each feeding level in an ecosystem. This energy pyramid shows the amount of energy available at each tropic level showing the food energy progression. The pyramids contain energy starting with the producers (plants) at the bottom to primary consumers, tertiary consumers and so on up to the top of the food chain. The most common units are grams per square meter per year or calories per square meter per year.
