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.
