Which type of population growth is shown in this graph?

A graph has time on the horizontal axis and population size on the vertical axis. The population size was constant for a period of time, increased rapidly, and then became constant again.

Logistic growth.

Explanation:

The logistic growth curve can be defined as the growth curve that forms a sigmoid like structure and starts with constant population for a period of time and then increases rapidly with the time and then it becomes constant.

The graph shows a time on the horizontal axis and population size on the vertical axis.

The graph shows that the population first starts using the resources and then starts growing, after that the as the resources starts depleting graph attains a constant line after which there can be no growth because of lack of resources and carrying capacity of earth.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
