Question

why must animals eat food but plants do not eat food

Answer 1

Animals must eat food in order to obtain the necessary nutrients and energy to support their bodily functions, growth, and maintenance. This is because animals are unable to produce their own food through photosynthesis like plants can. Plants, on the other hand, do not need to eat food because they are able to make their own food through the process of photosynthesis using sunlight, water, and carbon dioxide. This allows plants to produce the necessary sugars and nutrients they need to survive and thrive.
