All the living beings in a living environment constitute biodiversity. These living beings are extremely varied, but can be classified into different species. A species includes beings that look alike and can reproduce. In order to know which species an animal that we observe belongs to, it is possible to use an identification key. To do this, we use specific characteristics to create nested groups (formerly a classification tree). Living beings can have related characteristics. For example, dogs and cats both have 4 legs, a skeleton, eyes, a mouth, etc. Mind map: https://maitrelucas.fr/carte-mentale/...

My advice: it is obviously essential to concretely observe the world around us using an observation notebook and a camera. In the notebook, it is possible to observe the characteristics of each living being encountered: the number of legs, the colors, the size, etc. With the photos, I recommend classifying living beings based on the characteristics of animals and plants. Thanks to this classification, it is possible to easily observe the family ties between species. Skills: Use different criteria to classify living beings; identify family ties between organisms. Common character, heredity and family relationship.
