Answer:
adenosine triphosphate
Explanation:
Your energy does come from food, but not directly. All cells, like that in Figure 1.1, use chemical energy carried by ATP— adenosine triphosphate. ATP is a molecule that transfers energy from the breakdown of food molecules to cell processes.
The answer is 2. where the leaves provide the food for the plant by photosynthesis, and sunlight is required to carry out photosynthesis.
Atoms that are unstable undergo radioactive decay,
Elements with half life(that's how we know that it decayed),
Atoms that release energy and particles(like alpha beta and gamma particles) and,
Elements that have turned into a new element (as in radioactive decay no. of protons can decrease)
And to be precise the elements that have neutron to proton ratio of more than 1 undergo radioactive decay, since the nuclear attraction gets all weird after that.
