MNPS Q1 Science Biology 2022-2023
Human Activities and Earth's Atmosphere
Evidence from scientific studies supports the claim that human activities are contributing to the
increasing average global surface temperature on Earth as observed for the past 100 years. The
concentration of greenhouse gases in Earth's atmosphere have increased during this time and are
thought to be the major cause for changes in global climate Graph 1 represents the relative
contribution of human activities that are likely causing global climate change. Graph 2 represents the
relative amounts of various greenhouse gases in the atmosphere.

Unit B - Rainforests are being clear-cut in order to make room for more profitable
crops that can be used as biofuels. In Brazil, a monoculture consisting of fields of
soya beans is being planted, replacing the native rainforest ecosystem that often
consists of thousands of species.
Unit B - Compare the previous rainforest ecosystem and the new monoculture
ecosystem with respect to biodiversity and population size.
Your response should include
· an explanation of biotic limiting factors
an explanation of abiotic limiting factors
a discussion of the availability of habitats and niches
