As already mentioned, all animals need to eat, and every species has its own favorite food. But why do they need to eat? With a full belly, the animal’s chance to successfully breed increases. However, the animal will only be full for a while, and when they get hungry again, the population growth returns to normal. For example, boars don’t like herbs and ignore herb bushes completely; instead, they love to eat fresh corn from farm fields.
But how does this affect the farm fields? If a boar family decides to live on a farm field, farmers cannot continue their work, as boars are aggressive animals and chase away every settler. As already mentioned, this is not a dead end for the poor farm: boars will run away from hunters and military units when they approach the boars.
All animals will mate and breed automatically, but before giving birth to a new animal, every animal checks its surroundings to see that it is suitable for a newborn. First, a lonesome animal is not able to mate. There must always be two adult animals of the same species close to each other. Second, is the animal ready for mating? Animals cannot give birth every second. They need a break in between. Third, how many animals are already living in the area? Animals try not to destroy their own habitat by overpopulating. If there are already too many animals within one habitat like the forest, the population growth will decrease a lot. Last but not least, a well-fed animal has higher chances of giving birth compared to a hungry animal.
Chickens are a bit different, as they lay eggs. Sometimes, chickens are just laying eggs, and sometimes a new chick is hatching. This leads us to an important question: which came first, the chicken or the egg? We still couldn’t find the answer!
Fish, in general, are different from all other animals. Not every fish can be seen, but if one jumps out of the water, it’s an indicator that more fish are at that spot. If no fish can be observed, then none are living in that area.
Like every other animal, fish have their own lifecycle. They are born, live, and die. They can reproduce and move around. They don’t need food, but they provide food to a fisher who catches fish from the water.
Different fish species have their own habitat like all of the other animal species. Some live in the sea, others in lakes, and some of them can even live in both lakes and seas.
