You’re a vehicle owner. you recognize what your vehicle takes to function and what stops it from functioning.
Can you guess what it is? you bought it! It’s fuel. a bit like your vehicle, all living organisms require energy to function, grow and heal. The source of this energy is food. The study of food is primarily referred to as nutrition. As you recognize that to sustain life you would like to stay feeding your body and it’s not just you but all living beings require nutrition to survive.
Types of nutrition
To fully understand the phenomenon of nutrition, it’s important to review its types. It’s classified into two main types:
We all know that plants also feed like humans and animals do. But, it’s important even for a layman to know the terminology and science behind these various modes of feeding.
Autotrophic nutrition is found in autotrophic organisms. These organisms are self-dependent in terms of their food making process. This process is named photosynthesis. So which creatures does one think are those that make their own food? They’re the trees around you or the plants you see a day . Next time you see a tree, just repeat it to yourself that it’s autotrophic because it makes its own food.
Adding to your knowledge, photosynthesis may be a process during which plants manufacture their food, food which isn’t what we eat. Plants munch on sunlight and water. They consume water, CO2 from the atmosphere and sunlight energy to manufacture the sugar and starch, which is that the nutrition of plants.
On the opposite hand, heterotrophic nutrition is found in heterotrophic organisms. These organisms believe other organisms for his or her food. Now the organisms on your mind are presumably humans and animals. That’s true but to know the varied ways during which the various heterotrophic organisms derive their nutrition, let’s discuss them one by one:
Herbivores- These are the animals who are a bit like your vegetarian friends who always eat greens and refrain from eating meat. They’re plant lovers!
Carnivores- These are the animals that devour other animals. They’re wild and dangerous so just run away once you see them around yourself. they could eat human flesh too if they’re very hungry.
Omnivores- These are the organisms who… let’s cut it short. It’s you! Yes you’re an omnivore. You’re called one because you’ll eat both plants and animals. albeit you don’t eat animals because you’re too kind and emotional, you continue to are an omnivore because you’ve only chosen to become a vegetarian; however, you’re naturally born with the tendency to eat both animals and plants.
Cannibals- Well, this wasn’t the a part of the list, but since it’s happening within the world then why not mention it too? Cannibals are the humans who eat other humans. Gross! Right? But it’s possible that somewhere someone drooled while reading this- no pun intended. But i feel cannibals don’t got to be added as a replacement category of heterotrophic creatures. Rather, they’re more like what you call “evolved omnivores” who perhaps have crossed the bounds of humanity.
Key Facts and Statistics of Nutrition:
Our physical body mainly needs 7 sorts of nutrients: carbohydrates, protein, fats, minerals, vitamins, fiber, and water.
Carbohydrate, fat, and, protein are macronutrients needed in larger amounts.
Minerals and vitamins are micronutrients needed in small amounts.
All of the nutrients don’t provide energy, but they’re still important e.g. fiber and water.
Protein forms about 16% of a mean person’s weight .
Water constitutes around 62% of a mean person’s weight .
