Macrotermes natalensis is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Macrotermes natalensis rather than just read about it. In short: Macrotermes natalensis is a fungus-growing termite species of South Africa that belongs to the genus Macrotermes. This species is associated with the Termitomyces fungal genus.

Key takeaways

Macrotermes natalensis belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Macrotermes natalensis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Macrotermes natalensis from memory before moving on to harder problems.

Reference excerpt

Macrotermes natalensis is a fungus-growing termite species of South Africa that belongs to the genus Macrotermes. This species is associated with the Termitomyces fungal genus. M. natalensis has domesticated Termitomyces to produce food for the colony. Both termite species- fungal genus- are obligate and mutually beneficial where termite relies on the fungus to break down for plant materiel and nutrient resource. In contrast, the fungal species obtain plant material and optimal conditions for growth. M. natalensis has become a well-studied fungus-growing termite species, and its 1.3 gigabase pair genome was one of the largest sequenced insect genomes as of 2014.

Colony caste system All the fungus-growing termite colonies are similar caste systems. Each caste plays a different role in the colony, but it is not yet known how caste selection occurs. The primary reproductive caste or royal pair is made up of a king and a queen. The winged alates make up the secondary reproductive caste. Sterile castes do not possess any reproductive capacity and include workers and soldiers, both major and minor.

Termitomyces in a colony Termitomyces fungi play a major role in termite nutrition. They also influence termite survival and caste development. The fungal garden is managed by the worker caste. In a mature M. natalensis colony, older workers collect dead plant material along with Termitomyces asexual spores from their habitat and pass these on to the younger workers. The young workers only stay in the nest. They receive the plant material and ingest it along with the Termitomyces spores. Later, young workers defecate this blended plant material, along with fungal spores, somewhere in the colony nest. It forms a "comb", where the fungal mycelium establishes a dense network. The Termitomyces fungi use the nutrients from the comb and complete their life cycle with fruiting bodies or fungal nodules.

Worked examples

Example 1 — a first encounter with Macrotermes natalensis

Start with the simplest possible case. Write down what Macrotermes natalensis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Macrotermes natalensis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Macrotermes natalensis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Macrotermes natalensis

In research: Macrotermes natalensis appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Macrotermes natalensis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Macrotermes natalensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Blattodea of Africa, Insects described in 1898, Insects of South Africa, so understanding it makes those chapters shorter.
In everyday life: Look for Macrotermes natalensis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
