Nutrition is the process by which organisms obtain and utilize nutrients, essential for energy production and growth.
The basic unit of classification is Species, for example, Panthera leo (lion).
Respiration can be aerobic (with oxygen) or anaerobic (without oxygen).
The highest taxonomic rank is Domain, which includes Archaea, Bacteria, and Eukarya.
Reproduction is the biological process by which new individual organisms are produced, which can be sexual or asexual.
The Kingdom classification groups organisms based on fundamental traits, such as Animalia and Plantae.
Excretion is the removal of waste products from metabolic processes, essential for maintaining homeostasis.
Movement is the ability to change position or location, which can be voluntary or involuntary.
Biological classification helps in understanding relationships, organizing biological diversity, and facilitating communication.
Sensitivity is the ability to respond to environmental stimuli, involving sensory organs and nervous systems in animals.
Growth involves an increase in size and mass, which includes cell division and differentiation.
