Big Idea #18

A. Living things all share basic needs for life.

B. Living organisms acquire the energy they need for life processes through various metabolic pathways (photosynthesis and cellular respiration).

C. Matter and energy are recycled through cycles such as the carbon cycle.

I think it means:
Plant, animals, people, etc. all have to have basic needs to live.
Matter and energy go through certain cycles to be able to recycle.
