A full cycle is like doing a circle all the way around. It's like taking a ride on a big circle and ending up right where you started.
In some cases, full cycle can mean doing all the steps of something, like baking a cake. You start by getting all the ingredients and putting them together, then baking it in the oven, and finally taking it out of the oven and letting it cool before you can eat it. This is called a full cycle because you've done all the steps necessary to complete the task.
Another example of a full cycle is when you plant a seed and watch it grow into a plant. You start by putting the seed in the soil and giving it water and sunlight. Then, you watch as it sprouts up from the dirt and grows bigger and bigger until it's a full-grown plant. It's a full cycle because you've watched it grow from beginning to end, and it will eventually produce seeds that you can plant again to start the cycle all over.
Overall, when we talk about a full cycle, we mean completing all the steps necessary to do something or watching something go from beginning to end, like taking a ride on a big circle.
