Study Notes
Ecosystems
- Ecosystems are biological communities of interacting organisms and their physical environment.
- They encompass both biotic (living) and abiotic (non-living) components.
- Key characteristics include the flow of energy and the cycling of nutrients.
- Energy flows through the ecosystem in one direction, typically from the sun through producers (plants) to consumers (animals).
- Nutrients are recycled within the ecosystem, returning to the environment and being reused.
- Different ecosystems have varying levels of biodiversity and are shaped by unique environmental factors like climate, geography, and substrate.
- Ecosystems can be classified into different types based on their dominant characteristics, such as terrestrial (forests, grasslands, deserts), freshwater (lakes, rivers, swamps), and marine (oceans, coral reefs).
Habitats
- Habitats are specific environments where particular species live and thrive.
- Habitats are characterized by specific abiotic factors such as climate, temperature, water availability, and sunlight.
- They also include the biotic factors of the ecosystem, like the availability of food and predators.
- Living organisms adapt to their habitat by developing specialized traits.
- The physical and chemical properties of habitat determine the organisms able to survive in those conditions.
- A species' needs and adaptations help dictate its preferred habitat.
- Different species may have similar habitat needs but not necessarily overlap.
- Competition among species for resources can play a crucial role in habitat selection and distribution.
- Habitat loss and degradation are significant threats to biodiversity.
- A species' habitat correlates with its survival and reproduction potential.
- Organisms in a habitat have specific roles.
- Different ecosystems contain a variety of habitats.
- Human activities can impact habitats, sometimes with detrimental effects.
