unsuitable
Definition
In science, unsuitable can mean not meeting the requirements for a particular purpose. It can also mean not being able to be used for a particular purpose.
For example, a material that is not strong enough to withstand the weight of a building would be unsuitable for use in construction.
Another example is a chemical that is toxic to humans and would be unsuitable for use in food.
In general, unsuitable things are not useful or effective. They may be dangerous or harmful.
How can the word be used?

Etymology
The word "unsuitable" comes from the Latin word "inaptus", which means "not fit". The word "inaptus" is made up of the prefix "in-" (not) and the word "aptus", which means "fit".
The word "unsuitable" was first used in English in the 14th century. It is often used to describe something that is not appropriate for a particular purpose or occasion. For example, a formal dress would be unsuitable for wearing to the beach.

AQA Science Exam Question and Answer
Question:
Explain the concept of unsuitability in the context of ecological niches. Describe the factors that can make an environment unsuitable for certain species. Provide an example of an animal that thrives in a specific niche and discuss why other niches may be unsuitable for its survival.
Answer:
The concept of unsuitability in ecological niches refers to conditions within an environment that are unfavourable or incompatible with the survival and successful reproduction of a particular species. Ecological niches encompass the specific roles and requirements that a species has within its habitat.
Several factors can render an environment unsuitable for a given species. These factors include abiotic elements such as temperature extremes, pH levels, and availability of resources like food and water. Biotic factors, such as competition with other species for limited resources or the presence of predators, can also contribute to unsuitability.
A compelling example of a species thriving in a specific niche is the koala (Phascolarctos cinereus). Koalas are adapted to a diet of eucalyptus leaves and have a low metabolic rate, allowing them to conserve energy in their sedentary lifestyle. While eucalyptus leaves provide a suitable food source, they are also tough and have limited nutritional value. This adaptation makes the koala's digestive system unique, enabling it to extract nutrients from the leaves efficiently.
However, the koala's specialised diet and adaptations limit its suitability to habitats with abundant eucalyptus trees. In environments where eucalyptus trees are scarce or absent, the koala would face challenges in finding suitable food, making those niches unsuitable for its survival.
