Hi, according to the question, the a part, so when a population of seabirds arrives a newly formed volcanic islands, then population growth factors follows the logistic growth curve.
00:20
And this is because they do not still adapt to the new environment.
00:28
So they do not adapted to the new environment.
00:37
So there is a lag phase initially.
00:45
So initially lag phase.
00:49
Now when they get adapted, then they have a second phase called exponential phase.
01:00
Now seabirds generally require fresh water also so as the materials dry up.
01:06
Third phase of the stationary growth start.
01:11
So then stationary growth where the number of birth is equals to the number of death occurs.
01:23
Hence they follow the logistic growth curve.
01:38
So this is the answer for the a part.
01:40
Then for the b part, when a single colony of bacteria is placed in a petri plate that has enough resources, still there is a lag phase...
