Two mice of opposite sex mate and 20 days later get 10 kids
Within 12 hours after giving birth, the female can get pregnant again.
It is normal for mice to have 5-6 litters a year, but I suppose theoretically up to 17-18 litters can be produced by a supermum.
The pups get fertile after at most 50 days and can then have their own litters.
In less than a single year two mice can become (If no predators eat them)
Day 001, 2
Day 021, 2+10
Day 041, 2+10+10
Day 061, 2+10+10+10
Day 081, 2+10+10+10+10+50
Day 101, 2+10+10+10+10+10+50+50

My oh my.... If all survives and have enough food, and in ideal conditions have a litter as often as theoretically possible, 2 mice can become a large inbred family of more than 2.000 individuals only after 200-210 days.
As you can see on the above chart of days, the development is exponentional.
Mice, Rats, Rabbits, Pigs, all have a very steep curve of how many they can become under ideal condition in very short time.
Pigs take longer to get mature, but litters are large and ideal conditions still mean a very large family within short time.

The best description for the exponential growth of species is if the resources available are unlimited, each species can grow to its full potential. This leads the species to grow in numbers.
Yes and K is Logistic growth
Exponential Growth is when the growth rate of a mathematical function is proportional to the function's current value. Exponential growth is when an animal or whatever object increasing at an increasing rate. For example 2, 4, 8, 16, 32, 64 etc. This is exponential growth because it is multiple by a consistent number, or two. The key part is that is it multipled not added which would be lineal growth.
implementation of exponential groth
That means that the growth is equal to, or similar to, an exponential function, which can be written (for example) as abx, for constants "a" and "b". One characteristic of exponential growth is that the function increases by the same percentage in the same time period. For example, it increases 5%, or equivalently by a factor of 1.05, every year.
