Study Notes
Review of Lecture 2
- Organelles are the structural and functional units within cells.
- Cells are composed of coordinated organelles.
- There are two main types of cells: prokaryotic and eukaryotic.
- Eukaryotic cells are compartmentalized by membranes.
- Metabolism is the process of transforming matter and energy.
- Energy is the ability to rearrange matter.
- Different forms of energy include kinetic, thermal, and potential.
- Life is a self-controlled system capable of rearranging matter and energy.
- Life is highly ordered and can reproduce.
- Reproduction preserves information through a code passed to offspring.
- DNA stores biological information as nucleotides.
- Cell division creates new life and transfers genetic information to offspring.
- Variation introduces new biological information.
Basics of Ecology
- Ecology is the study of interactions between organisms and their environment.
- Different hierarchical levels of ecology exist.
- Organismal ecology studies how an organism's structure, physiology, and behavior adapt to its environment.
- Population ecology analyzes factors that affect population size and its changes.
- Community ecology investigates how species interactions influence community structure.
- Ecosystem ecology focuses on energy flow and chemical cycling within ecosystems.
- Landscape ecology examines the exchange of energy, materials, and organisms across landscapes.
- Global ecology studies how regional exchange impacts the biosphere.
The Biosphere
- The biosphere encompasses all ecosystems and landscapes on Earth.
- It is a closed system in terms of matter, with minimal inputs and outputs.
- It is an open system in terms of energy.
