difference between plant and animal nutrition
Answers
Answer:
Plant nutrition:-
Most plants are able to use sunlight as their primary source of energy, in a process called photosynthesis. This process enables them to turn carbon dioxide from the air into food, which they can store and later break down to meet their energy needs. The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide. Hydrogen comes from water, which they absorb through their roots. Plants split hydrogen (H) off from water (H2O) and emit the leftover oxygen into the air. This is good for us animals, because we breathe in oxygen and breathe out carbon dioxide. This cycle of oxygen and carbon dioxide between plants and animals ties together almost all of the living things on earth.
The last of the primary elements needed by living things is nitrogen, which plants must absorb through their roots. Although air contains nitrogen, plants are unable to use it directly and must rely on nitrogen-containing compounds absorbed from the soil or created by certain bacteria living in and around their roots. The rest of the minerals that are necessary for life must also be absorbed through the roots. These elements are present to a greater or lesser degree in all soils. The limiting elements are usually nitrogen, phosphorus, and potassium, which is why these are the primary components of most fertilizers. Different plant species require different amounts of these minerals, which is why some plants grow better than others in any particular soil.
Animal nutrition:-
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement. Movement requires a lot of energy, so animals generally require substantially more energy than plants do.
Animals are only able to get energy by breaking down certain complex substances that are made of carbon, hydrogen, oxygen, and nitrogen. These substances are called proteins, sugars, and fats. The bodies of all living things are primarily made from these substances, along with water. So by consuming plants, bacteria, and/or other animals as food, an animal can get both the energy it needs to power its body and the carbon, hydrogen, oxygen, and nitrogen it needs to maintain its body and grow. The living things consumed by an animal also contain the other minerals necessary for life, which the animal can absorb and use for itself. All animals also require certain complex molecules which they cannot make for themselves. These are called vitamins, and are also absorbed from the bodies of the organisms consumed. Different animal species require different amounts of the various vitamins and minerals, and also differ in what kinds of food they are capable of eating. Finally, just like plants, animals require a steady intake of water to replace whatever is evaporated or excreted from their bodies. Those animals that are not able to absorb enough from their food must drink extra water to make up the difference.

Answer:
1.plants make their own food but animals don't make their own food, they get their food from plants and by other animals.
2.In photosynthesis plant converts carbon dioxide and water (in the presence of light energy and chlorophyll) to glucose, water and oxygen
