The life processes that occur in both people and trees are:
c. making food and growth
While trees can perform photosynthesis to make their own food, people do not directly make food but obtain it through consumption. However, both undergo the process of growth.
If we reconsider "making food" specifically, it applies only to trees (photosynthesis), so we might need to refocus.
Considering the context, let's focus on the alternatives for life processes common to both:
- Both grow over time.
- Trees can move slightly (through growth) but do not move in the same way animals do.
The correct pairs for common life processes would actually be more specifically related to growth and reproduction.
Thus, strictly focusing on growth and reproduction would be a sound summary.
However, if including movement is considered more broadly (growth as movement), it might provide a suitable answer contextually. So, if that's the premise we're using, we could say b. growth and movement captures the essence of living behavior.
If choosing strictly from the provided options, d. reproduction is true across species.
