Introduction to resources in video games and the food chain analogy.
Imagine that you are doing a mission to get resources in a video game. The crucial parts you need to build everything else in your game are the supplies you collect, like wood, stone, or gold. These important materials are usually needed in more quantities than the amazing things you can make with them, right? The food chain follows the same logic.
Plants as producers and their food creation process.
Plants are like your basic resources in nature because they are producers. Through a process known as photosynthesis, they create their own food by using sunlight, water, and carbon dioxide. Because of their ability to multiply and grow, they act as a food source for several herbivores, which are their main eaters.
Herbivores eating plants as their main food source.
To fuel themselves, herbivores like deer and rabbits eat these plants. They mimic the first thing you create in your game using your resources, such as a house or a tool.
Carnivores consuming herbivores as advanced products in the food chain.
Think about carnivores (secondary consumers), like wolves or lions. To fuel themselves, they eat herbivores. They mimic the complex things you create in your game, such as a fancy palace or a potent weapon. Similar to how many resources are needed to create a few advanced products, many herbivores must exist to support a small number of predators.
The 10% energy transfer rule and the need for a larger energy base.
Each level of the food chain has less energy available as you move up it. The 10% rule, according to which a consumer only receives around 10% of the energy from the level below it, is a result of this. The rest goes to waste, mostly as heat. As a result, in order to maintain life, we need more species at the base of the food chain—such as plants and herbivores—than at the top—such as predators.
Importance of a larger number of plants and herbivores to support top predators.
Imagine this: If your game only contained one tree, you wouldn't have enough wood to build a house, much less a castle. Similar to this, there wouldn't be enough energy if there were only a few plants or herbivores in the environment.
Analogy between basic resources in video games and the energy base in the food chain.
In a nutshell, the fact that energy decreases as we climb up the food chain explains why there are more herbivores than carnivores in a food chain. To support the creatures at the top, we need a larger base of energy at the bottom. You need a lot of basic resources, just like in your game, to make the cool, sophisticated stuff!
