* Only plants perform photosynthesis: While plants are the most well-known photosynthetic organisms, some bacteria and algae also perform photosynthesis.
* Only animals perform cellular respiration: While animals are the most prominent examples of organisms using cellular respiration, all living things, including plants, use cellular respiration to generate energy.
A more accurate statement would be:
"Plants are the primary producers in most ecosystems and perform photosynthesis to create energy from sunlight. Both plants and animals use cellular respiration to convert that energy into a usable form."
This emphasizes that:
* Photosynthesis is not exclusive to plants.
* Cellular respiration is a universal process for all living organisms, including plants.
