Study Notes
Body Systems
- Skeletal System: Provides support and protects internal organs. Composed of bones.
- Muscular System: Responsible for movement. Composed of muscles.
- Nervous System: Controls and coordinates bodily functions. Composed of nerve cells, including the brain and sensory organs.
- Respiratory System: Facilitates oxygen intake and carbon dioxide removal.
- Circulatory System: Transports oxygen, nutrients, and waste throughout the body. Composed of the heart, blood, and blood vessels.
- Excretory System: Eliminates waste products from the body through organs like the liver, kidneys, bladder, skin, and lungs.
- Digestive System: Breaks down food and absorbs nutrients.
Factors Affecting the Ecosystem
- Biotic Factors: All living organisms within an ecosystem, including plants, animals, fungi, and bacteria.
- Abiotic Factors: Non-living components of an ecosystem, such as temperature, sunlight, water, and soil.
- Habitat: The specific place where an organism lives.
- Biomes: Large-scale ecosystems characterized by specific climate and vegetation, such as forests, deserts, and grasslands.
- Producers: Organisms that produce their own food through photosynthesis, such as plants.
- Consumers: Organisms that obtain energy by consuming other organisms, such as animals.
- Decomposers: Organisms that break down dead organisms and waste, such as bacteria and fungi.
Food Chains and Webs
- Food Chain: A linear sequence showing the transfer of energy from one organism to another.
- Food Web: A complex network of interconnected food chains, representing the flow of energy within an ecosystem.
- Ecosystem Changes: Can occur due to natural events (e.g., floods, fires) or human activities (e.g., pollution, habitat destruction).
Threats to the Ecosystem
- Extinction: The complete disappearance of a species.
Protecting the Ecosystem
- Afforestation: Planting trees to restore forests.
- Recycling: Reprocessing materials to reduce waste and conserve resources.

Description
This quiz explores the various body systems such as the skeletal, muscular, nervous, respiratory, circulatory, excretory, and digestive systems along with their functions. Additionally, it covers factors affecting ecosystems, including biotic and abiotic components. Test your knowledge on how these systems work and their importance to the human body and environment.
