homeostatosis
The billions of cells in your brain are called neurons. They fire when they receive the proper stimuli and pass the message through synapses and dendrites.
The nervous system responds to external signals through nerve cells or nerve fibers. The special senses and homeostasis work together to respond to changes to give the general awareness to the changes.
Flamingos have very long legs which are an adaptation that allows them to eat from deeper water than most other birds. Flamingos can also excrete salt through a special gland.
Function: Regulation of the endocrine system by cyclic rhythms of such hormonal stimuli related to light and sleep patterns through positive and negative feedback responses, permits this complex system to regulate the body's chemistry.

through closing their leaves or flowers like "touch me not plant"
Variability of heart rate reacting to external stimuli
I believe it is called the "bell". The rhopalial lappet are nerve rings through the bell that respond to stimuli, such as touch, and may cause the bell to contract.
The jellyfish can respond to stimuli and adapt to some changes. However, in terms of intelligence, this animal has primitive senses, and no brain or nervous system. It can identify a prey through chemosensory pits.
Yes, sunflowers feel sensitivity. They "feel" sensitivity in that they respond to stimuli, such as the direction and amount of light or damage to parts of itself. It does not "feel" in that it cannot experience pain, discomfort, or emotional distress.
Assuming you are referring to the different types of "environmental stimuli," as in biology, the answer would include many sources. All living things (organisms) respond to environmental stimuli; this is one of the seven key characteristics of living things (including evolution, order, regulation, growth and development, reproduction, and energy utilization). So, for example, our bodies can respond to physical damage by making us aware of it through our feeling of pain. The "fight or flight" response can be triggered by threatening environmental stimuli. Or, a Venus fly trap will snap shut when an insect lands in its trap.
All living things exhibit five characteristics: 1. They grow and develop. 2. They reproduce. 3. They obtain and use energy. 4. They respond to stimuli. 5. They have a complex cellular organization.
