Which three steps describe how an animal obtains and uses energy for growth?


AFirst, an animal eats another organism. Then, food is built into larger molecules. Next, the animal's cells use molecules to make new cells.
BFirst, food is built into larger molecules. Then, the animal eats another organism. Next, the animal's cells use molecules to make new cells.
CFirst, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.
DFirst, food is broken down into smaller molecules. Then, the animal eats another organism. Next, the animal's cells use molecules to make new cells.

Verified Answer :

Final answer:

Animals obtain energy by consuming other organisms, breaking down food into smaller molecules, and using those molecules to create new cells. This process is essential for their growth and development. Each step plays a critical role in energy transformation and cellular metabolism.


Explanation:

How Animals Obtain and Use Energy for Growth

An animal's energy acquisition and utilization process is crucial for its growth. This process can be broken down into three primary steps:

  1. First, an animal eats another organism. This can be a plant or another animal, depending on whether the animal is a herbivore, carnivore, or omnivore.
  2. Then, the food is broken down into smaller molecules. This digestion process involves enzymatic reactions that convert complex food into smaller, simpler molecules, such as amino acids and glucose.
  3. Next, the animal's cells use these molecules to make new cells. This involves cellular processes like protein synthesis, where amino acids are assembled into proteins needed for growth and repair.

Through these steps, animals are able to transform the energy stored in food into the energy needed for their metabolic activities and cellular structures, supporting their overall growth and development.
