1. Charles Darwin recognized that Thomas Malthus' argument applies to animal and plant
populations as well as to human populations. Look at the figure and choose which observation
Darwin made from this. Human population size Food supply Population growth outstrips food

While humans have the ability to outstrip their food supply through unchecked population
growth, plants and animals live in a balance with their food supply O Human and animal models
of population growth have nothing in common. O Humans will inevitably outstrip the available
resources necessary to sustain themselves and the population will diminish. O The difference
between the growth of a population and its size allowed by the food supply shows the possibility
of selection through the struggle for existence.
Solution
The difference between the growth of a population and its size allowed by the food supply shows
the possibility of selection through the struggle for existence.
Explanation
The difference between the potential growth and the maximum size allowed by the food supply
denotes the number of individuals lost in the struggle for existence, and thus it represents the
opportunity that natural selection has to sort populations based on even the smallest differences
in form.
