The Animal Food Chain
Today we are going to learn about the animal food chain, also known as the food pyramid.
Every living thing needs energy in order to live and this energy is found in the food they eat. Living creatures are situated on various levels of the food chain depending on what they eat.
Fruits and vegetables are at the bottom of the trophic pyramid. These are called primary producers as they can make their own food. They do this through a process called photosynthesis which is a combination of the sun’s energy with both water and nutrients obtained from the soil.
The second stage of the pyramid is dedicated to the primary consumers. These are the herbivores, which are animals that eat directly from the producers, like these zebras o these cows…
The secondary consumers are animals which feed on other animals. They are carnivorous as they eat meat such as these wolves, this eagle or these sharks. Omnivores are also secondary consumers; do you remember what they are? They are animals which eat both meat and plants like these pigs, these bears or even us, human beings.
The last of the consumer groups is that of the tertiary consumers. In this group we find the scavengers, like vultures which feed on dead animals which are in a state of decomposing…yuck! That really is disgusting, don’t you think?
After the consumers the third level in the food chain is dedicated to the decomposers. The decomposers are bacteria and mushrooms which are in charge of consuming animal remains. The function of the decomposers is really important as they turn organic wastes into inorganic materials, creating new energy in the form of nutrient-rich soil. This then completes the cycle of life, as the producers in the pyramid’s first level benefit from it, and so whole new food chain starts.
The truth is, nature is very intelligent and therefore we must protect as well as respect it tremendously… including all its inhabitants for as you have just witnessed, all of them, no matter how insignificant they might seem, are fundamental for life’s balance, our marvelous life. So now you know!
Goodbye friends and until the next Happy Learning TV video.
