Define the following: Climate Weather 2. List at least two similarities and two differences between the long and short-term carbon cycle. Population Ecology 1.What are three key features of a population? How does natural selection have an effect on whether a population will grow or shrink in size? the long-term average weather of a region The state of atmosphere of a region at any given time in respect to temp , moisture , wind , a barometric pressure Similar Aff - ↑ I . both cyclical processes of carbon I . short-term occurs in years while long-term in atmosphere takes millions of years 2 .
