Answer:

Energy flows in a one-way direction i.e. unidirectional flow

Explanation:

Matter and energy both pass through an ecosystem as organisms feed on one another. However, as rightly emphasized in this question, matter in form of elements such as water, nitrogen, phosphorus etc. moves in different directions and is recycled within and between ecosystems through closed loops called biogeochemical cycles.

Contrarily to how matter is recycled in an ecosystem i.e. within and between, ENERGY only flows in one direction. Energy enters an ecosystem in form of light (sun) and is passed down from one trophic level to another starting from the producers. This unidirectional pattern of energy flow differentiates energy flow from matter recycling.

What will occur if solution A containing 400 mosmol/L non-penetrating solute is separated by a biological membrane from solution
vampirchik [111]

Answer:

The volume of solution B will increase

Explanation:

In a non-penetrating solute, there is denial of a solute to cross the cell membrane.This implies that the solute will not be able to cross the cell membrane.  So if the biological membrane is serving as a partition between a solution A containing 400 mosmol/L non-penetrating solute and a solution B containing 600 mosmol/L non-penetrating solute, The volume of solution B will increase.

Harman [31]
