Waste Removal
Waste removal is the process of eliminating and managing waste materials from the body and the environment. It is an essential aspect of maintaining a clean and healthy living environment.
Types of Waste
- Solid Waste: Includes household trash, industrial waste, and construction debris.
- Liquid Waste: Comprises wastewater from households, industries, and agricultural activities.
- Gaseous Waste: Includes air pollutants released from industrial processes and vehicle emissions.
Human Waste Removal
The human body eliminates waste through various systems:
- Excretory System: Removes metabolic wastes through the urinary system.
- Respiratory System: Eliminates carbon dioxide and other gaseous waste products through breathing.
- Digestive System: Excretes solid waste through the process of defecation.
Environmental Waste Removal
Environmental waste removal involves managing and disposing of waste to prevent pollution and protect natural habitats. Methods include recycling, composting, and proper disposal in landfills or incineration facilities.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
