Day 2 Reflections by Shiying

EQ1. What is a system?
A system is a group of things or organisms working together or rely on each other in order to survive or function. Every organism or part in a system is important in order to carry out its function or plainly to survive.

EQ2. How humans and the environment are dependent on each other
Humans rely on the environment for food, water and air in order to survive. We make use soil in order to plant and cultivate food; we make use of water from rivers and lakes to obtain fresh water; plants give out oxygen through the process of photosynthesis. When humans cultivate crops, they are also assisting the plants in the pollination process. Therefore, humans and the environment depend on each other to survive
