Functional diversity: The physiological functions of organisms can vary greatly.

Structural diversity: Organisms can vary widely in their tissue and organ structures.

Morphological diversity: Organisms can vary widely in appearance and form.

According to cell type: Organisms can be divided into prokaryotes and eukaryotes.

According to nutritional mode: organisms can be divided into autotrophs and heterotrophs.

Adaptability: Organisms survive and reproduce through their ability to adapt to their environment.

Metabolic ability: Organisms can maintain life activities through metabolism.

Cellular Structure: All living things are composed of one or more cells.

Genetic material: The genetic information of living things is stored in DNA.

Bioremediation: Using organisms to repair polluted environments and restore ecological balance.

Ecological agriculture: protecting soil and water resources through biological planting and breeding.

Biomanufacturing: Harnessing biosynthetic capabilities to produce chemicals, fuels, and more.

Biodegradation: Harnessing the decomposition capabilities of living things to process waste and pollutants.

Breeding improvement: improving crops through selection and breeding of superior varieties.

Biological control: The use of biological pest control to reduce pesticide use.

Gene therapy: The use of genetic engineering technology to treat genetic diseases.

Drug research and development: The development of new drugs through the study of living organisms.

Predation relationship: Food chains and food webs reflect the predatory relationship between organisms.

Symbiosis: A mutually dependent and mutually beneficial relationship between organisms.

Stability: Ecosystems can remain relatively stable.

Destructive factors: Environmental changes, human activities, etc. will destroy the ecological balance.

Biome: A group of organisms in the same area.

Habitat: The environmental conditions provided for organisms to survive and reproduce.

Evolutionary tree: Organisms can express the genetic relationships of different species through evolutionary trees.

Speciation: Speciation can be explained by processes such as isolation, mutation, and selection.

Molecular biology: The genetic relationship of organisms can be inferred through comparison of DNA sequences.

Biogeography: The distribution of organisms in different regions can reflect evolutionary processes.

Fossil record: Fossils record the form and structure of living things in the past.

Adaptive advantage: Characteristics that facilitate survival and reproduction gradually spread throughout the population.

Natural Selection: Organisms that adapt to their environment are more likely to survive and reproduce.

Genetic variation: The genetic information of living things can vary.
