The period of time in population growth when the organism is adapting and growth is slow is called what?

• A. Lag time
• B. Lag phase
• C. Interception
• D. ITCZ

Answer: (B)

In population growth curves, the initial period after organisms are introduced to a new environment where they’re adjusting and not yet multiplying rapidly is the lag phase. During this phase, cells are metabolically active, synthesizing enzymes and building cellular components, but the overall population size changes only a little as they adapt to nutrients, temperature, and other conditions. Once adaptation is complete, growth picks up and enters the exponential phase. The term lag time can describe how long this preparatory period lasts, but the standard label for the phase itself is lag phase. The other terms shown aren’t related to population growth.
