Yes, wind or pockets of air with a different temperature than surroundings can trigger a motion detector. Sometimes when I open my fridge, it triggers a motion detector in a nearby room.
As far as we know, infrared radiation is not harmful to humans. However, you must never leave a new born baby or an animal in a car on a sunny day. The infrared light will get trapped in the car and the baby or animal has a very high risk of dying. This is the same thing that happens to our atmosphere, causing global warming.
Yes, heat lamps do emit infrared rays as a form of heat. Infrared rays are a type of electromagnetic radiation that produces heat when absorbed by objects or surfaces. These rays are commonly used in heat lamps to provide warmth in various applications, such as in outdoor heating, animal husbandry, and therapeutic treatments.
Pit vipers such as rattlesnakes and some pythons have specialized organs called pit organs that can detect infrared radiation, allowing them to see heat signatures of their prey. This gives them a unique hunting advantage in low-light conditions.
Quite simply, because there are individual differences between species. In this case, the range of the electromagnetic waves they can see is a little larger for some animals. I don't think that ALL animals, or even all animals with eyes, can see a larger range of radiation than humans.
Echolocation is actually a process- it can't hit anything. In echolocation, high frequency sound waves are sent out by an animal. When these sound waves hit an object, they bounce off of it and reflect back to the animal. The animal can gather information about the object from these sound waves such as its size, shape, and distance.
In IR (InfraRed) detector is a circuit that receives an infrared input, either in an alarm or as a heat sensing device. In an alarm circuit, using an infrared beam rather than a laser has both advantages and disadvantages. Passive heat sensors rely on a general increase in temperature to identify a likely source, e.g. an animal, person, or vehicle engine.

No animal uses "infrared" to catch prey. Infrared is a man-made mechanical device to locate objects in darkness - that's a simplistic explanation, the actual process is more complicated. Some reptiles have sensory organs in their heads that can perceive nearby warmblooded animals, but that's not infrared.

It is anything alive

Animal products can contribute to inflammation in the body due to their high levels of saturated fats and certain proteins that can trigger an immune response.
