Sika deer benefit from the resources in grasslands more than forests; if deforestation occurred, producing more grasslands in the region, the carrying capacity for sika deer population would increase. You can refer to the answers. Exponential growth is when a population's per capita growth rate remains the same regardless of the population size which causes the population to grow faster as it gets larger.
