We prepare our food to satisfy our hunger and hunger occurs due to the mineral and nutrient needs of the body. How do animals get their food?
• What materials do we use to cook/prepare our food?
• Where do we get those materials from?
We depend on animals and plants to get our food. In the same manner, the plants and animals also depend on each other for survival. The story of human civilization itself has “Food” as a reason for its flourishment. When the family sizes of our ancestors increased, the need for food also increased and they settled down at a place where every basic need was easily available, like – Food, water and land. This acted as a base for civilizations, before, our ancestors used to get food by only hunting and gathering animals and plants.
What are Herbivores and Carnivores?
We all have grown up watching wild animals and plants, if not real, at least from wild Photo/Videography channels.
• Did you ever wonder why the teeth structure of Tiger doesn’t match with the Cow’s teeth structure?
• Why fierce animals like Lions, Wolves, Dogs, and Cheetahs etc have very sharp and bit longer Canine teeth?
The teeth structure and digestion system of Cow is comfortable and shaped for easy grinding and digesting vegetation. So, Herbivores can’t tear, rip and digest meat with their teeth and existing digestive system. The animals which eat only Plants or Vegetation are called HERBIVORES.
The fierce animals have sharp and longer Canine teeth as they have to cut, rip and tear the meat or flesh of other animals or birds to survive. These animals won’t eat plants because they cannot digest vegetation properly and they need a diet consisting of at least 70% of meat in the food they consume.
• Do you remember any plants that eat meat or insects?
• What type of consumers are these plants?
The plants and animals that eat only meat or insects are called CARNIVORES.
Special type consumers – Omnivores
When we observe our teeth, we find that we have both structures of teeth as Herbivore and Carnivores. Like us, Bears, Raccoons, Pigs and Rats etc also have the same teeth structure similar to human teeth structures.
• Why do we have both teeth structures?
• What type of consumers are we?
Have you observed when your Mom/Dad is preparing chicken curry they fry chicken meat with ingredients like – Curry leaves, Coriander; Garlic, Ginger, Potato etc. Here, we humans are eating both plants and animals! The teeth structure of both plant and animal eating only meat/insects is different as it includes both Canine and flat Molar teeth for tearing meat and grinding grass as well. Some argue that Canine teeth may disappear after certain generations as the evolution of humans and teeth is still in progress. The animals which eat both plants and animals for their survival are called OMNIVORES. Some examples of Omnivorous consumers are – Humans, Bears; Chickens, Cockroaches, Crow etc.
Tiny food producers
All the animals and plants depend on each other for food or they themselves are food for each other. Other than animals and plants that become food for each other, the products of small insects can also be food for others like from a Honey bee. Have you ever thought about how honey is produced?
• How do bees accumulate honey?
• Why do we love eating honey?
Honey bees accumulate honey through collecting nectar from the plants and their flowers. The nectar is sweet and nutritious which turns to honey when sucked by the honey bees. It helps food needs of bees in bad and poor weather conditions as well as humans and other animals like – Bear, Raccoon and Honeybadger. Humans have developed a device to extract honey easily which works on the concept called Centrifugation.
To get the understanding of different types of food consumers and hands-on knowledge of Centrifugation device and it’s working mechanism; we can use different learning and teaching materials like – Models, Visual aids and other hands-on learning materials.
