What factors led to the dramatic decrease in population growth rates in Kerala, India?Compare the case of Kerala to India’s national population control program put intoplace in the 1970s.
If population growth is assumed to be density dependent in all four populations, what will happen to these populations sometime after generation 10?
1. Population size will grow monotonically.
2. Rate of population growth will decrease.
3. Rate of population growth will remain the same.
4. All populations will follow the curve of population
For this assignment you will be building a concept map of the factors that influence population size. You can include ideas concerning how populations grow and also have they are regulated. Create a concept map that connects together 18-20 ideas/terms/features.
