Answer:
True, the flow of energy through living systems can be modeled as food chains
Explanation:
A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers. The path is linear as
the energy present in one step is transferred to the next.
For example, grasses and scattered trees growing in a field,the grass and trees are producers that use sunlight to carry out
photosynthesis. Grasshoppers are herbivores that live in grassland ecosystems. They get energy
by eating grass and leaves.
Scientists are actually working on a type of clock that is more accurate than the atomic clocks we use today. It is called an optical atomic clock and it measures atomic oscillations using light from the visible spectrum.
