Enumerate the five common characteristics of life discussed.
Gathering and Using of Energy
Nutrient Uptake and Processing
Waste Elimination
Adapting and Evolving
Reproducing and Continuing of Life
The process by which energy is released by the breakdown of food substances.
Cellular respiration
All chemical processes, reactions, and energy changes happening inside the body.
Metabolism
The process by which organisms acquire food.
Nutrition
Two types of energy acquisition?
Autotrophs and Heterotrophs
Organisms like plants capture energy from sunlight through photosynthesis.
Autotrophs
Nutrients are broken down and converted into usable forms of energy through processes like cellular respiration.
Processing
Involves the absorption of essential nutrients from the environment or food.
Nutrient Uptake
Organisms like animals obtain energy by consuming other organisms.
Heterotrophs
A crucial biological process that involves the removal of harmful metabolic byproducts from an organism’s body.
Waste Elimination
Refers to an organism’s ability to move or manipulate its environment. It allows organisms to find food, escape predators.
Motility
Level in which movement of substances occur within cells (e.g., cytoplasmic streaming).
Cellular Level
Movement of the entire organism (e.g., walking, swimming, flying).
Organismal Level
The ability of an organism to respond to stimuli from its environment. This responsiveness is crucial for survival, enabling organisms to adapt to changing conditions.
Irritability
