The answer to this question would be: by producing buffer
The pH of optimal growth of bacteria might be different. Some bacteria can grow in an acid condition called acidophile, other live in base condition called alkaliphiles and the rest live in neutral pH condition called neutrophiles. The bacteria can maintain their internal pH by producing acid, base or buffer. If the surrounding pH is too acid, the bacteria can reduce the H+ concentration by producing base. If the condition is too alkali/base, the bacteria can produce acid by doing fermentation.
Answer:
A particular population limiting factor or factors must have been removed
Explanation:
The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.
For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. <u>It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community. </u>
