Answer: Given below
Explanation: <em>The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. ... They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell</em>

One reason could be that they do not have most of the seven characteristics of life (reproduction, homeostasis, heredity, response to the environment, growth, cellular organization, and metabolism.)
Answer:
new technological advances
Explanation:
The carrying capacity indicates the maximum population of a particular species that a given area of habitat can support over a given period without destroying or depleting the resource base.
Carrying capacity can be affected by factors such as technological advances, trade and use of fossil fuels for energy . Changes in technology modify the carrying capacity of a population. An example is the use of irrigation and fertilisation in agriculture or shortening rotations between crops, which increases the number of people who can be fed from the resources of a given population due to increased yield.
