All organisms need energy to live atp is the fuel that powers all the activities of cells. which statement best describes how ferns, people, and flatworms obtain energy? ferns and flatworms absorb food from their surroundings, while people must digest food found in their surroundings. ferns produce glucose that can be broken down by cellular respiration, while flatworms and people digest foods containing glucose for use in cellular respiration. producers such as ferns do not require a source of energy, while flatworms and humans must consume food for energy. ferns produce atp during photosynthesis, while flatworms and people produce atp during digestion.

Ferns produce glucose that can be broken down by cellular respiration, while flatworms and people digest foods containing glucose for use in cellular respiration.

Explanation:

Ferns, humans & flatworms all require cellular respiration to live. This energy-productive process occurs in the cell cytoplasm and mitochondria. However, for cellular respiration to occur, it has to work on an energy-rich substrate. In cells, this substrate is usually glucose. Ferns are autotrophs hence can make glucose by photosynthesis because they have chlorophyll molecules. However, flatworm and humans are heterotrophs meaning they have to consume other organic compounds to get this glucose.
