Study Notes
Biodiversity and Ecosystems
- Biodiversity refers to the variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
Habitats and Species
- A habitat is the natural environment in which an organism or species normally lives or occurs.
- A species is independent if it can survive and reproduce on its own without relying on another species.
Vertebrates and Invertebrates
- The main difference between vertebrates and invertebrates is the presence or absence of a backbone.
- Vertebrates have a backbone, while invertebrates do not.
Interdependence and Food Chains
- Interdependence refers to the way different species in an ecosystem rely on each other for survival.
- If one type of animal disappears, it may have a ripple effect throughout the ecosystem, potentially affecting other species that rely on it.
- Disrupting the food chain, a series of organisms that eat other organisms, can have consequences for the entire ecosystem.
Species and Their Environments
- If you match a bird to its habitat, it would most likely live in an environment that provides the necessary resources for its survival, such as food, water, and shelter.
Ecological Relationships
- The term that best describes the relationship between plants and animals in an ecosystem is interdependence.
Key Characteristics of Biodiversity
- The characteristic that best defines biodiversity is the variety of different species present in an ecosystem or on Earth.
