Question

Effect (The way a living thing acts when it senses something in its environment​).

Answer 1

Living organisms detect changes in their environment and respond to them.

Step-by-step explanation:

All living things detect changes in their environment and respond to them. A response can take many forms, from the movement of a unicellular organism in response to external chemicals (called chemotaxis), to complex reactions involving all the senses of a multicellular organism. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (called phototropism).
