Seasonal movement of animals from one region to another for food, breeding, etc.

Substances that are only needed in very small amounts but essential to organisms to produce enzymes, hormones and other substances fundamental for proper growth and development.

Substances that are only needed in very small amounts but essential to organisms to produce enzymes, hormones and other substances fundamental for proper growth and development (WHO, 2015).

The small-scale physical requirements of a particular organism or population.

A change in gene frequency within a population. Evolution at this scale can be observed over short periods of time - for example, between one generation and the next, the frequency of a gene for pesticide resistance in a population of crop pests increases. Such a change might come about because natural selection favored the gene, because the population received new immigrants carrying the gene, because some nonresistant genes mutated to the resistant version, or because of random genetic drift from one generation to the next.
