Question

Why do organisms need to take food?


Open in App
Solution

Organisms need to take food:

  1. Energy is required by living things to maintain their biological functions, and it can only be obtained through food.
  2. The nutrients that are digested and absorbed by the body come from food.
  3. Inside the cell, these nutrients are turned into energy, which the cell then uses to carry out various biochemical operations.
  4. In contrast to plants, which are autotrophs, animals must obtain their energy from other organic matter.
  5. Therefore, food is necessary for organisms' growth and survival.
