Animal Resources:

A variety of useful resources or products utilized by humans are derived from plants and animals. Recall that plants and animals are classified as living things (or living organisms). 

Resources from animals refer to useful materials derived from livestock and other animals for the beneficial use of man. These include cattle, sheep, goats, chickens, turkeys, pigs, horses, donkeys, camels, rabbits, elephants and so on.

Please read on resources from living things (plants) here.


The resources humans derive from animals and utilizes for their use are explained below:


1. Food (Meat, Fish and Egg): These are great sources of protein in our diet. They are important for growth and repair of worn out tissues. Example of animals reared for meat include pigs, chickens, turkeys, cattle, sheep and goats. Animals reared for fish are tilapia, catfish, carp, tuna and salmon respectively.

Please read how to start a home based fish farming here.

Eggs are great sources of protein in human diet, and these are derived from poultry. Poultry birds include chickens, turkeys, guinea fowl, ducks and geese.


2. Dairy Products: They are also referred to as milk products or lacticinia. Simply put, they are products made from the milk of cattle, nanny goats, ewe and water buffalo. Such products include yoghurt, butter, cheese and canned milk. They are highly nutritious to humans.

Please read various interesting facts for students here.


3. Hides and Skin: They are derived from the skin of animals after they had been dried, tanned and processed. Specifically, hides are gotten from the 'skin' of large animals like cattle, buffalo, horses, camels, crocodiles and alligators while skin are made from the 'skin' of small animals like rabbits, goats, snakes and pigs. They are used in the manufacture of leather products like belts, shoes, bags, furniture and sports equipment.


4. Beast of Burden: These are animals utilized by humans to carry heavy loads for their benefit. They can also function to pull heavy objects like a plow or cart for man's benefits. Animals like donkey, camel, horse, ox and mule are examples of beast of burden.

Please read on agricultural machines and their uses here.


5. Wool: They form a protective covering on sheep and other hairy animals like camelids, rabbits and goats. When processed in the textile industry, they can be used to make clothes, carpets, blankets and upholsteries.

Note: About 90% of the world's wool are derived from sheep. The wool from one sheep is termed a fleece. Those from many sheep are referred to as clip.


6. Dung: A dung refers to the feces of animals like cattles, sheep, goats, pigs, horses and chickens. These can be used as organic manure on farmlands. In this regard, they add organic matter and other nutrients like nitrogen to the soil. They also increase the population of beneficial soil bacteria and fungi.

Please read on agricultural terms and meanings here.


7. Medicine: Certain products derived from animals may be used as medicines. Examples are calcium from animal bones, iron from animal blood, dessicated thyroid and heparin derived from pigs, premarin derived from horses, gelatin capsules derived from the cartilage of animals, vitamin D3 and lanolin from sheep.

Note: The African forest elephant (loxodonta cyclotis) is listed as critically endangered specie on the International Union for Conservation of Nature (IUCN) red list. They should therefore be protected and their indiscriminate killings prohibited by law.


9. Bones: The bones of animals can be processed into bone powder or bone paste. These may be used as health-care products, dietary supplements in animals and raw materials for other products. Bones may also be used to manufacture flutes, buttons, fertilizers and weapons.

Please read on bones of the human skeleton here.

10. Horns: Animal horns have shown to be useful especially in ancient times. They have been used as musical instruments, for example, the shofar made from the horn of a ram. Horns may also be utilized for drinking purposes in some traditions.

Please read on harmful traditional practices in Nigeria here.

The horns of antelopes have also been used to produce traditional Chinese medicines. Also, we see the usage of horns in furniture and home decorations.


11. Feather: Feathers are derived from poultry birds. They are used to manufacture decorative products like costume accessories, earrings, fans, masks, boas, flowers and hats.

Amazing facts in Basic Science

According to scientific research, if the first tear drop comes from the right eye, it’s tears of joy. If it comes from the left eye, then it is as a result of pain

Dentistry is the oldest profession in the world. This is considered true because a research conducted by the University of Bologna, Italy on a 14,000-year-old skull found that one rotten tooth in the jaw had been deliberately scoured and scraped with a dental tool

Scientific research has it that the human nose can distinguish more than a trillion different odors

Tiger fur and skin - Len Academy

Tigers have striped fur. So also is their skin

Red-Billed Quelea - Len Academy

The most common wild bird in the world is native to Africa, and it's the red-billed quelea with a population estimated to be around 1.5 billion

Of all animals, mosquitoes hold the record of killing most humans annually. They are responsible for the deaths of 725,000 - 1,000,000 persons yearly

Antibiotics fights and kills bacteria. However, they do nothing to a virus

All insects have six legs. However, dragonfly has six legs but can't walk

The chin is defined as the protruding part of the face below the mouth, formed by the apex of the lower lip. It is shown below:

Interestingly, humans are the only animals with chin

Cranberries - Len Academy

Ripe cranberries will bounce like a ball. For this reason, they are nicknamed 'bounceberries'. They will also float in water

Notable points in Basic Science

We have six classes of food. These are:

  1. Carbohydrates

  2. Proteins

  3. Fats and Oils

  4. Vitamins

  5. Mineral Salts

  6. Water

In humans, roughages are not classified as one of the classes of food. This is so because they aren't digested. Instead, roughages facilitate the movement of bowels in the large intestine (colon); and for this reason, they can become useful in treating constipation.

Food refers to anything that is ingested by living organisms, giving them nutrients and thus enabling them to stay alive.

As an instance, 99% of a panda's diet is bamboo. In this case, bamboo is considered as food to a panda since it provides a source of nutrient and keeps it alive. This is shown in the image below:

The only process in nature that actively enriches our atmosphere with oxygen is photosynthesis. Every other process like respiration, burning and combustion takes away oxygen from it. In addition, they introduce carbon(IV)oxide (CO2) into the atmosphere.

Photosynthesis is also the only process that takes away carbon(IV)oxide (CO2) from the atmosphere.

Photosynthesis is defined as a process by which green plants manufacture food by utilizing carbon(IV)oxide and water in the presence of sunlight.

Oxygen is given off as a by-product of photosynthesis. In regards to this, it is recommended that each person plants a tree.

Matter is composed of particles which can be:

  1. Tightly packed together (as seen in solids).

  2. Loosely packed together (as seen in liquids).

  3. Completely separated (as seen in gases).

The movement of the particles of matter is a function of the overall kinetic energy present in them. You can think of kinetic energy as energy in motion.

An increase in the particles' vibrational, rotational or translational motion will imply an increase in temperature while a decrease in the particles motion (vibrational, rotational and translational) will mean a decrease in temperature. Based on this knowledge, we can therefore define temperature as the measure of the average kinetic energy possessed by the particles of matter.

Intelligence Quotient (IQ) is a score derived from a set of standardized tests developed to measure a person's cognitive abilities in relation to their age group.

IQ may also be defined as the ratio of mental age (MA) to chronological age (CA) multiplied by 100.

Below are some formulas pertaining Intelligence Quotient:

  • IQ = MA x 100 ÷ CA

  • MA = Mental age

  • CA = Chronological age

  • IQ above 100 = Brilliance

  • IQ that equals 100 = Average

  • IQ below 100 = Below Average
