3.  Is the change in a population over time, and can be quantified as the change in the number of individuals of any species in a population.  In biology, the term population growth is likely to refer to any known organism (plant, animal, bacteria, protist, fungi)

5.  Exponential Growth  Logistic Growth

7.  Takes place when a population of organisms live in an ideal environment: More than enough food, shelter, water, mates, etc. When organims are new to an environment and have no immediate predators When a population´s numbers have been drastically reduced by a catastrophic event  Under this conditions populations increase fast.

8.  Population growth is only limited by their physiological condictions:

9.  Shape of the typical Exponential Growth Graph has a J-shaped curve

10.  Does this graph show exponential growth? Whooping Crane

12.  The exponential growth model assumes unlimited resources, which is never the case in the real world.  No population can grow indefinitely forever. Why?

13.  Organisms need resources to keep alive.  If a population increases, also will the demand of resources and they will get very crowded.

14.  There is a limit to the number of individuals that can occupy a habitat.  That is the carrying capacity of the ecosystem  Which is the maximum population size that a particular environment can support at a particular time with no degradation of the habitat.

15.  When populations exceed carrying capacities, this happens: organisms start fighting for resources to accomplish survival others die of starvation, by the attack of predators By the end, population growth stabilizes

16.  Shape of the typical Logostic Growth Graph has an S-shaped curve

17.  Do these graphs show a Logistic Growth?
