<h2> What are proteins made of?</h2><h3>Proteins are made up of smaller building blocks called amino acids, joined together in chains. There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape. Some, like keratin, the hair protein, form long fibres. Others, like haemoglobin, the protein that carries oxygen around your body, are roughly spherical.</h3>

If biodiversity is lost in an ecosystem, it will lead to decrease in ecosystem resilience. Biodiversity loss is a major concern now. With the extinction of many species, ecosystem might collapse. Removing a single species can result in a partial collapse of the ecosystem. For example: honey bee colony collapse situation. Without honey bees, humans would struggle or fail to grow certain important crops. With more loss of biodiversity it may become hard for our very survival also.
