Study Notes
Understanding Biodiversity
- Biodiversity refers to the variety of life in a specific habitat or ecosystem, encompassing the diversity of species, genetic variation, and ecosystem diversity.
- High biodiversity enhances ecosystem resilience and stability, supporting complex interactions among species.
Biodiversity Comparison: Coral Reef vs. Desert
- Coral reefs exhibit significantly higher biodiversity than deserts due to their complex structures that provide various niches for organisms.
- Coral reefs are home to thousands of species, including fish, invertebrates, corals, and algae, while deserts have fewer species adapted to extreme conditions.
Interdependence
- Interdependence describes the relationship between organisms where they rely on one another for survival, resources, and ecosystem balance.
- This concept is critical in maintaining ecological networks, where the extinction or decline of one species can impact others.
Vertebrates vs. Invertebrates
- Vertebrates possess a backbone or spinal column, while invertebrates do not have a backbone, making vertebrates part of the phylum Chordata.
- Vertebrates typically have more complex body structures and systems compared to invertebrates, which are more diverse and simpler in form.
Examples of Vertebrates
- Mammals: Examples include humans and dolphins.
- Birds: An example would be eagles or sparrows.
Examples of Invertebrates
- Mollusks: Examples include octopuses and snails.
- Arthropods: Examples include spiders and crabs.
Exoskeleton Function in Invertebrates
- An exoskeleton provides structural support and protection for invertebrates, allowing them to retain moisture and resist environmental pressures.
- It also facilitates movement by acting as an attachment point for muscles, enhancing mobility.
Function of a Vertebrate Skeleton
- A vertebrate skeleton supports body structure, protects internal organs, and facilitates movement by providing leverage for muscles.
- It plays a crucial role in movement efficiency and flexibility.
Bone Definition
- Bone is a dense, hard connective tissue that forms the structural framework of vertebrate skeletons and provides strength, support, and protection.
Adult Human Skeleton
- The adult human skeleton typically comprises 206 bones, which provide structure and facilitate movement while interacting with muscles and joints.
