The energy released in a radioactive decay arises because the nucleus is moving from one energy level to a lower energy one. The link below gives a good outline explanation in the Explanation section.

Plants are a common example of organisms that produce their own energy through photosynthesis, using sunlight to convert carbon dioxide and water into glucose. Some bacteria and algae are also capable of producing their own energy through similar processes.
A bicycle does not produce energy on its own; instead, it converts the rider's pedaling motion into mechanical energy to propel the bike forward. The energy required to pedal a bike comes from the rider's muscular effort.
Organisms at the bottom of an energy pyramid, such as producers (plants), are always autotrophic. Autotrophic organisms can produce their own energy through photosynthesis or chemosynthesis, forming the foundation of the energy pyramid by converting sunlight or inorganic compounds into organic matter.
Solar energy and nuclear energy are both efficient in their own ways. Solar energy is renewable and non-polluting, but it is dependent on weather conditions and location. Nuclear energy is a reliable source of power, but it produces radioactive waste and has associated safety concerns. The efficiency of each depends on factors such as cost, environmental impact, and energy output.
Yes, each one is unique.
A non-radioactive element is an element that has at least 1 isotope that is not radioactive. The means that at least one isotope has a stable nucleus that does not break down by shooting off high-energy particles.
passive elements
Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category. Non luminous bodies are those which do not produce their own light. For example: moon etc.
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
Wind energy can provide all the energy that we need
We call these autotrophs.
None, actually.
Heterotrophs cannot produce their own food, if that is what you mean by energy. For example, humans are heterotrophs. Autotrophs, however, can produce their own food (like plants, algae, etc). Both heterotrophs and autotrophs need energy to survive, they just use it in different ways.

autotrophs produce their own energy while heterotrophs get energy by eating other organisms.
Fish bones are not typically radioactive on their own. However, they can accumulate certain trace amounts of radioactive elements from the water or food they consume. But the levels are generally very low and not considered a significant health concern for consumers.
