Answer:
By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.
Explanation:
There are five kingdoms:
- Monera: bacteria
- Protista: amoeba, paramecium, euglena
- Fungi: yeast, rhizopus
- Plantae: flowering and non-flowering plants
- Animalia: animals (vertebrates and invertebrates)
Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.
Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.
Mutualism, The question is asking us to choose the correct symbiotic relationship.
There are THREE types of Symbiosis.
SYMBIOSIS is a relationship between two organisms.
I'll give you a quick run-through of each one.
1. MUTUALISM is where both organisms benefit, from one another.
2. COMMENSALISM is where one organism benefits, and the other is totally unaffected.
3. PARASITISM is where one organism benefits, while the other is harmed.
