Final answer:
The inner principle of change in natural things is the inherent tendency of living organisms and natural processes to undergo changes over time. It can be observed in the growth and development of living organisms and ecological processes.
Step-by-step explanation:
The concept of the inner principle of change in natural things refers to the inherent tendency of living organisms and natural processes to undergo changes over time. This principle is observed in the growth and development of living organisms, as well as in ecological processes and systems.
For example, in biology, the inner principle of change can be seen in the process of metamorphosis in insects, where a caterpillar transforms into a butterfly. This inner principle drives the transformation and development of the organism in a specific direction.
Another example is the concept of natural selection in evolution, where the inner principle of change leads to the adaptation and survival of species in response to changing environmental conditions.
