Cell: The cell is the basic structural and functional unit of an organism. It is the smallest unit of life that can perform all the processes of life.

Tissue: A group of similar cells that perform a specific function is called tissue. There are four types of tissues in animals - epithelial, connective, muscular, and nervous.

Organ: An organ is a group of tissues that perform a specific function. Examples of organs in animals include the heart, lungs, stomach, and brain.

Organ System: An organ system is a group of organs that work together to perform a specific function. Examples of organ systems in animals include the respiratory system, digestive system, and nervous system.

Organism: An organism is a single living entity that is capable of carrying out all the processes of life.

Population: A population is a group of individuals of the same species living in the same area.

Biotic Community: A biotic community is a group of populations of different species living in the same area.
