◉ How does the bionomial system work? Answer: The first part of the
name is the genus and the second is the species.
◉ How does the pyramid of biomass work? Answer: The pyramid of

◉ What is the carbon cycle? Answer: The carbon cycle is where carbon
is recycled so it can be available again to other organisms.
◉ How is CO2 removed from the air? Answer: CO2 is removed from
the air through PHOTOSYNTHESIS. Photosynthesis is basically the
process where green plants and some other organisms use sunlight to
make nutrients from carbon dioxide and water.
◉ What are the 3 ways that CO2 is released into the air? Answer: -
Respiration form animals and plants
- Decomposition from fungi and bacteria. ( Remember that
decomposition is the process of breaking down and rotting and decay.)
