Question

A change in the immediate external environment of an organism.​

Answer 1

$\huge\sf{answer:-}$

➽Understanding the interactions of an organism and its environment is essential for us to integrate ultimate and proximate causation on a global scale. Organism–environment interaction includes all organisms including animals, plants, and non-eukaryotes, etc. because all of them are responsive to environmental change including those that are human-induced. A mechanistic approach is important for us to understand why some organisms can cope with change and others cannot.

Answer 2

A change in the immediate external environment of an organism is known as a stimulus

Explanation:

• A stimulus is defined as an organism's reaction to a change in the external environment.
• The external stimuli observed by our body create a suitable electrical impulse in the sensory neurons.
• These sensory neurons further spread the information in the form of electrical impulses to the brain or spinal cord.
• The external stimuli include light, touch, heat, pain, vision, and equilibrium or the body balance.
