<u> Bacterial growth curve-</u>
The phase in the bacterial growth curve which is defined by zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.
<u>Phases of the bacterial growth curve-</u>
The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.
- Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
- Log phase- The second phase where the cells are dividing and increasing in numbers.
- Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
- Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.

Answer:
The answer is wet and moist places.
Explanation:
Many of the plants in phylum polypodiophyta are ferns. Each group of fern plants consisting of spores or sporangia is called sorus. Fern are primitive plants and have an ancient history.
Many ferns are known since the time of fossil fuels. Other kinds of ferns are grape ferns and adder's tongue ferns. These ferns belong to the order Ophioglossales.
All of the ferns genera have complex and old histories. These plants are mostly found in wet and moist places and live in lakes and ponds where water is abundant.
Answer:
I believe it's ecological succession.
Hope that helps!
