Explanation:

1. For biotic vs abiotic: Biotic factors are living components of an ecosystem, while abiotic factors are non-living physical/chemical components.
2. For the table: Each row corresponds to a letter in "S T E R N G R R", representing core life processes, their definitions, and common examples.

Answer:

1. Difference and examples:

• Biotic factors are living organisms in an ecosystem that interact with other components. Example: A deer (a living animal that feeds on plants and is prey for predators).
• Abiotic factors are non-living, physical or chemical elements in an ecosystem that support life. Example: Soil (a non-living substrate that provides nutrients and structure for plants).

1. Completed table:

S	Life Process: Sensitivity	What it means: Ability to detect and respond to environmental stimuli	Example: A plant bending toward sunlight
E	Life Process: Excretion	What it means: Removal of waste products from metabolism	Example: Humans excreting urea via urine
R	Life Process: Respiration	What it means: Release of energy from food molecules	Example: Humans breathing to take in oxygen for cellular respiration
N	Life Process: Nutrition	What it means: Obtaining and processing food for energy and growth	Example: A tree absorbing sunlight and nutrients via photosynthesis
G	Life Process: Growth	What it means: Increase in size, mass, or number of cells	Example: A puppy growing into an adult dog
R	Life Process: Reproduction	What it means: Production of new individuals to sustain the species	Example: Birds laying eggs that hatch into chicks
R	Life Process: Regulation	What it means: Maintaining stable internal body conditions (homeostasis)	Example: Humans sweating to regulate body temperature
