Answer:
1) Carrying capacity is the maximum number of individuals of a species that an environment can support.
2) Population - all the inhabitants of a particular town, area, or country.
3) An increase in population will inevitably create pressures leading to more deforestation, decreased biodiversity, and spikes in pollution and emissions, which will exacerbate climate change.
4) The three leading causes of population growth are births, deaths, and migration. Births and deaths are seen as natural causes of population change.
