Symbiosis is a relationship between two different species Symbiosis is a relationship between two different species. There are three main types of symbiosis. Symbiosis can benefit both organisms, it’s called mutualism. Or it can benefit one organism and harm the other parasitism. It can also benefit one organism and does not benefit or harm the other commensalism.

What are Amino Acids? Amino acids are the building blocks of protein. Proteins make up a living thing’s cells, skin, hair, etc. They are the building blocks of your body. The amino acids a living thing can make on its own are called non-essential amino acids. The amino acids a living thing must get from it’s food are called essential amino acids.

Evolution is the process that explains that all living things on earth are related and descended from a common ancestor. Scientists look for patterns in nature. If other insects have the same type of symbiosis found in pea aphids, does that mean they share a recent common ancestor? If the symbiosis found in pea aphids is not found in similar insects, that leads to even more interesting questions.
