Food consumed by humans and animals

Animals and humans cannot produce their own food and are dependent on plants or other animals. Hence they are called heterotrophs. (The word hetero means others and the word trophs means food/nutrition)

 




Heterotrophs can be classified into:

• Herbivores - eat only plants / plant products
• Carnivores - eat only flesh/meat
• Scavengers - organisms that feed on dead animals
• Omnivores - eat both plant products and meat 

  
Human beings consume food materials from both plants and animals


///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

 Even though heterotophs do not produce their own food, it is still not an easy job obtaining food. Watch this cheetah get a meal : https://www.youtube.com/watch?v=Ptpb51UquOo
  
After having viewed the cheeta video, in the comments tell me  which organism (living thing) is the autotroph, the herbivore and the carnivore?

Food Chain

When you think of the word chain, what comes to mind? Do you think of the chain on your cycle, or the chain your mother wears. 

A chain is basically a link

A link that connects living organisms wherein one organism is food for the next is called a food chain. 

All food chains begin with plants.

Food Web

What does the word web remind you of? A spider's web? The internet?  

Inter-connected food chains form a food-web

 What are you having for lunch today? Think of the food web involved in the food on your plate
