Final answer:
Giraffes eating leaves from a tree is an example of obtaining and using energy for metabolism in living organisms.
Step-by-step explanation:
Yes, the statement 'Giraffes eating leaves from a tree is the characteristic of life - OBTAIN AND USE ENERGY (METABOLISM)' is true. Giraffes feeding on leaves from trees is an example of obtaining and using energy for metabolism in living organisms. Giraffes obtain energy from the leaves they eat, which they break down through cellular respiration to release ATP, the energy currency of cells.
Plants, like the trees that giraffes eat from, are producers and convert sunlight into glucose through photosynthesis. The plant uses some of the energy from glucose for its own needs, but the excess energy is available to the giraffe when it consumes the plant.
Therefore, the act of giraffes eating leaves from a tree demonstrates the characteristic of life - obtaining and using energy through metabolism.
