Biotic vs. Abiotic Components
Distinguish between the 'Biotic' and 'Abiotic' components of a habitat.
Distinguish between the 'Biotic' and 'Abiotic' components of a habitat.
- Biotic Components: All the living organisms within a habitat, including plants, animals, fungi, and microorganisms.
- Abiotic Components: All the non-living physical and chemical factors in the environment, such as soil, water, air, sunlight, and temperature.
- Interaction: Biotic components rely entirely on abiotic factors to survive and thrive.

Bio means Life, Abiotic means Non-living
Universal Characteristics of Life
What are the core characteristics that universally differentiate living beings from non-living things?
What are the core characteristics that universally differentiate living beings from non-living things?
Living beings universally exhibit the following biological processes:
- Movement: Locomotion or internal/cellular movement.
- Growth: Irreversible physical increase in size.
- Nutrition: The need for food and energy.
- Respiration: Breaking down food to release energy.
- Excretion: Removal of metabolic waste.
- Response to Stimuli: Reacting to environmental changes.
- Reproduction: Producing offspring to continue the species.
- Death: The eventual cessation of all life processes.

Growth: Living vs. Non-Living
A cloud grows in size in the sky, and a salt crystal grows in a solution. Why are they not considered 'living'?

- Non-Living Growth (Accretion): Occurs purely by the external accumulation of material on the outside of the object. It is often reversible.
- Living Growth: Occurs from within (internally) due to cellular division and the assimilation of nutrition. It is a fundamental, irreversible biological process.
