Question

25.why is energy important to a living organism?

Explanation:

Living organisms need energy for essential life processes. These include metabolism (like photosynthesis in plants, cellular respiration in all organisms to convert energy for use), growth (building new cells/tissues requires energy), reproduction (processes like gamete production, embryo development need energy), response to stimuli (moving, sensing and reacting to environment), and maintenance (repairing cells, maintaining homeostasis like regulating temperature or pH). Without energy, these vital functions would cease, and the organism couldn't survive or perform the characteristics of life.

Answer:

Energy is vital for living organisms as it powers essential life processes: metabolism (e.g., cellular respiration to use energy, photosynthesis in plants to capture energy), growth (building new cells/tissues), reproduction (gamete production, embryo development), response to stimuli (movement, sensory responses), and maintenance (cell repair, homeostasis). Without energy, these functions stop, and the organism cannot survive or exhibit life characteristics.
