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.
no that is imposible
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.
Infrared: snakes, mosquitos, predators Ultra-violet: bees,
A machine to a physicist is probably anything except a living animal which can be made to do work when controlled by a human.
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.
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.
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.
no
anything
Its an animal.
anything with legs
-----Anything can be harmful to an animal.
no
It is anything alive
An animal bigger then your head really is anything like a monkey or a dog or a bunny exc. anything you can think of really.
