Vital Factors Required For Living Organisms

Living organisms! Who are these living organisms? So far I have written a lot about biology stuffs here on Smart Science Pro than physics or chemistry. I hope you have a good understanding about living organisms if you had time to read other science pieces.

Living organisms are the things that has a life, these things perform various vital activities with the help of vital factors which is required for their existence. Carl Linnaeus was the first scientist to introduce an efficient criteria for classifying all the living organisms on our planet.

What’s Inside of Life?

According to the natural classification of life, you have the chance of seeing 3 groups of living beings as animals, plants and microorganisms. There is a basic unit of structure and function to all living things. It is known as a cell.

Collection of cells form something we called as tissues. Tissues are presented in all multicellular organisms. Tissues together forms various organs such as eyes and these organs define various body systems of an organism. Every thing from a tiny cell to a body system requires some form of energy to continue its life, functions and growth.

The energy needed for the existence of living organisms are taken by vital factors. So let me explain each of these vital factors with simple experiments for you to digest things smarter.

#4 Vital Factors Essential For Life

I’m asking it from you, what are these 4 vital factors? If you already know them, that’s good. Okay, have you had some time for a picnic? Ya! I’m sure you always have lots of time for such interesting journeys than you spend for learning in the school.

I remember the first time I visited a Zoo which is full of wild animals that you can’t see in the concrete jungle. 😉 Our environment is full of animals, you don’t need to hit for a Zoo to see animals around you. Just visit a pond, fish tank or something like that. Stare at tree tops for a while to see some birds and so on.

All these animals require these vital factors to survive the living.

Air is a Vital Factor

Turtles belong to vertebrates group under classification of animals naturally. Have you seen turtles in your pond or in the Zoo? Turtles come out of the water after swimming for a bit under the water. Then they go under water again and follow the same procedure continuously.

What caused the turtles to come out like that? Actually, you know the answer already. Turtles come out of the water if the amount of air is not enough for the respiration.

There are people who sell innocent small chickens. These small chickens are kept inside boxes which have small circle holes. Then have you seen dog transport boxes have square holes. All these holes are there because animals require air always to perform vital activities.

Mountain climbers and divers have to wear special suites not because they want to be fancy, because they don’t need to have respiratory issues while enjoying the party! That’s why the suite has oxygen cylinders.

Above examples alone prove the validity of air as a vital factor for animal life, but what about the plant life?

You have heard a lot for this short time you’ve lived, but have you ever heard plants on moon? Nope! Not because moon doesn’t like to grow plants. Moon’s atmosphere does not have oxygen and it resulted in a bad atmosphere for the existence of life there.

All these backup the Air as a vital factor for all living beings.

Water is a Vital Factor

When it comes to water, it’s our life blood of all time. You or me cannot survive without water. In the photosynthesis factors post, I have explained that you cannot design an experiment to prove the necessity of water for the process of photosynthesis due to the death of plant as soon as you remove water from it.

It is same for all living beings. We all die after losing water from our bodies.

Water is a vital factor and it helps to purify your body, digest what you eat and excrete what is being digested. Those are few vital activities supported by water for animals. Food production of a plant is related to photosynthesis and water is required for plants to provide fruits you eat today.

Foods are a Vital Factor

As humans we have lot of interests over other animals. I always love to have a lunch with a chicken fried rice, but it’s not the only food which I love to eat. I know you too have many foods that you are passionate to have around the week.

Due to this interest, sometimes we forget why we eat foods. Frankly, it is not to play with our interests but to get the energy required to run our body systems continuously. Various foods have different types of nutrients which are the fuels of our body.

You can live 1-2 days normally without having food, but you can’t survive that much longer usually without drinking water. Anyway, Food is a vital factor for the existence of life on earth.

Every food chain starts with a producer which is always going to be a green plant. These plants are known as Autotrophic plants due to their ability of producing foods with the help of environment. All other animals and microorganisms are relying on green plants

Sunlight is a Vital Factor

Who doesn’t like to spend an hour in the morning sunlight? If you tell me to choose one between Hot and Cold, I’d definitely choose Hot because I love heat, flame and yellow color too. 😉 Therefore, I always like sunlight too.

Do you know our planet earth will be a cold hell if it wasn’t for the sun’s light? Yes! That’s true. You feel cold at the night. Right? Sun goes to the other hemisphere at night time for your country.

Additionally the sunlight energy is another factor for photosynthesis process. That fact alone proves sunlight is a vital factor for plant life. Want to test it? If you have a green backyard, then I assume you have grass in the floor. Now cover some grass leaves with a bucket or a coconut shell. Keep it same for few days and observe what happened to covered grass leaves.

You’d see the green color of the grass turned to yellow color.

Scientists have mentioned planets like Neptune shows properties of a very cold atmosphere. Neptune is away from sun’s exposure a lot and a lot and another lot. That’s why the planet is so cold. Suppose the sun’s gone for forever, what would happen to our planet earth? It’ll be cold same as Neptune where life couldn’t survive as it is now.

Therefore, sunlight also a vital factor for all living organisms.

As a summary, the 4 vital factors required for the existence of life on earth are,
