because they lack chlorophyll
Plants need sunlight, water, and carbon dioxide to make food through photosynthesis. Humans do not use sunlight directly to make food, as we rely on consuming plants or other animals that have already synthesized nutrients through this process.
Well the things that humans do need are water/food safety shelter that's all what we really need.
Humans do not get boric acid from food. Boric acid is a chemical compound used in some household products but is not an essential nutrient for human consumption. Sodium, water, protein, and starches are all nutrients that humans can obtain from food.
so the animals and humans can restock on their food they cant carry all of it in their sleds so the animals and humans can restock on their food they cant carry all of it in their sleds so the animals and humans can restock on their food they cant carry all of it in their sleds
Cows can't survive on gas alone. Neither can humans. Both cows and humans need food and water to survive, not just oxygen (which is a gas we breathe).
Sources of energy for humans include food, water, sunlight, and rest. Food provides the body with fuel in the form of carbohydrates, proteins, and fats. Water is crucial for maintaining bodily functions and hydration. Sunlight helps with the production of vitamin D, which is important for overall health. Rest allows the body to recharge and replenish energy stores.
Make their own food.
Chloroplasts use energy of sunlight to make food
Sunlight, Warmth, Energy, Food and Water are needed.
FOOD, WATER, SUNLIGHT, AND SUNLIGHT
Sunlight, a photosynthetic compound such as chlorophyll, and traces of magnesium.
The chlorophyll in a plant's leaf traps the energy from the sunlight. A plant need carbon dioxide, water and sunlight to produce food.
