An individual's ecological footprint is equivalent to the: total amount of food consumed by that individual.
There is no defined limit on the capacity of the brain. The brain's capacity cannot be measured as it is not subject to a defined "space" where the memory is kept, and it is not such that each neuron is responsible for a single memory. The brain has complex mechanisms of memory storage, that even improve if trained.
Answer: Increase
According to the competitive exclusion principle, when two or more species in an ecosystem are competing for the same resource. The one which has undergone favorable adaptation and more competing will be likely to derive those resource than the one which has not undergone adaptation or less adaptive to the environment and less competing. Squirrels and chipmunks compete for the same food source and this food source became scare one of the two species is likely to disappear according to the competitive exclusion principle because the degree of competition between two species will increase.
