Answer:
Biotic factor
Explanation:
Biotic factors are part of factors that determines the nature of the ecological system. They can either be living or dead organisms. Because they are considered to possess lives or had formerly existed, they are found in the biosphere and can reproduce.
Hence, to predict how the population of one species affects and is affected by the population size of another species or by its interactions with some abiotic factor, like rainfall. The ecological model uses a BIOTIC FACTOR.
This is because it is the interaction of the biotic and abiotic factors that determines the nature of the ecosystem.
Osmosis is said to be the tendency of a fluid, usually water, to pass through a semi permeable membrane (as of a living cell) into a solution where the solvent concentration is higher thus equalizing the concentrations of materials on either side of the membrane.
When sugar is placed on a straw berry, the thin film of moisture on the berry skin begins to dissolve the sugar. Once this happens, the dissolved sugar forms a higher solute concentration on the skin of the berry than that found in the (plant) cells of the berry. A concentration gradient is formed and water molecules from the berry cells move down that gradient to the outside of the berry skin and dissolve the sugar to form a gooey solution.
