Study Notes
Energy Storage Molecule
- Molecules that organisms use to release energy for survival.
Ecosystem
- Comprises all living (biotic) and nonliving (abiotic) components in a specific area, interacting with one another.
System
- A collection of interacting parts that form a complex whole.
Biotic Matter
- Includes all living and dead organisms within an ecosystem.
Abiotic Matter
- Consists of nonliving elements such as air, water, and rocks.
Producer
- Organisms capable of creating their own energy storage molecules like glucose.
Consumers
- Organisms that require consumption of other substances to obtain energy storage molecules.
Photosynthesis
- Process where plants' chloroplasts utilize sunlight, water, and carbon dioxide to create oxygen and glucose.
Photosynthesis Formula
- Carbon dioxide + Water → Glucose + Oxygen.
Examples of Energy Storage Molecules
- Key molecules include Starch, Glucose, Fat, and Glycogen.
Similarities Among Energy Storage Molecules
- Composed of carbon, hydrogen, and oxygen, all originating from producers.
Differences Among Energy Storage Molecules
- Glycogen, fats, and starch serve long-term energy storage but differ in atomic structure.
Carbon
- A fundamental atom forming both carbon dioxide and energy storage molecules.
Carbon in Matter
- Carbon exists in abiotic (carbon dioxide) and biotic (energy storage molecules) forms.
Photosynthesis and Carbon Transfer
- During photosynthesis, chloroplasts transform carbon dioxide into energy storage molecules, facilitating the movement of carbon from abiotic to biotic matter.
System Changes
- A change in one part of a system impacts the entire system's equilibrium.
Carbon Availability
- Increased carbon dioxide enhances the availability of carbon for producers, enabling more energy storage molecule production.
- Conversely, reduced carbon dioxide limits production capabilities.
Sunlight's Role in Production
- More sunlight allows producers to generate an increased amount of energy storage molecules from carbon dioxide.
- Less sunlight results in decreased energy storage molecule production.
Decomposers
- Organisms that extract energy storage molecules by breaking down dead matter, contributing to nutrient recycling.
Carbon Dioxide in Ecosystems
- Ends up as part of abiotic components, typically found in the atmosphere.
Cellular Respiration
- Process occurring in mitochondria where energy storage molecules and oxygen are converted into ATP energy, generating carbon dioxide and water as waste.
Cellular Respiration Formula
- Glucose + Oxygen → ATP energy + Carbon Dioxide + Water.
Comparisons of Photosynthesis and Cellular Respiration
- Both occur within cells; photosynthesis is exclusive to producers, while cellular respiration occurs in all organisms.
Carbon Movement During Cellular Respiration
- Energy release during cellular respiration converts biotic carbon (from energy storage molecules) into abiotic carbon (carbon dioxide).
Connection
- The act of linking two or more entities or concepts in biology, showing relationships within ecosystems and processes.
