Study Notes
Ecological Relationships Glossary
- Predator: An animal that actively hunts other animals as a food source.
- Prey: An organism that is hunted and consumed by another organism.
- Symbiosis: Close associations between organisms that typically live together and benefit from each other.
- Mutualism: A symbiotic relationship where both species involved gain benefits.
- Parasitism: A relationship where one organism benefits at the expense of another, causing harm.
- Commensalism: A relationship benefiting one organism while the other remains unaffected.
- Competition: The struggle for survival among organisms in a habitat with limited resources.
Types of Competition
- Interspecific Competition: Competition that occurs between members of different species.
- Intraspecific Competition: Competition occurring among members of the same species.
Ecological Relationships
- Trophic Cascade: Indirect interactions in ecosystems that can lead to significant changes.
- Negative Ecological Relationships: Relationships that negatively impact an organism.
- Positive Ecological Relationships: Relationships that positively influence an organism.
- Direct Ecological Relationships: Immediate interactions between different trophic levels.
- Indirect Ecological Relationships: Occasional interactions between different trophic levels.
Understanding Symbiosis and Related Concepts
- Ecological Relationship Models: Frameworks that describe interactions among organisms in ecosystems.
- Interpreting Graphs: The skill of analyzing and understanding what data visualizations represent.
Questions Overview
- Examples of Parasitic Relationships: Ticks feeding on dogs.
- Mutualistic Relationships Explanation: Ants and acacia trees benefit each other through their interaction.
- Definition of Symbiosis: Close living relationship between two species.
- Mutualism Clarification: Both species gain from the relationship.
Relationship Types
- Commensalism Example: A bird living in a tree where it is neither helped nor harmed.
- Mutualism and Commensalism: Distinction is crucial; mutualism benefits both parties while commensalism only benefits one.
- Parasitism Example: One organism benefits while harming another.
Comparing Relationships
- Predator/Prey Dynamics: The predator gains energy from consuming the prey, resulting in harm to the prey, akin to parasitism but differing in mechanism.
- Intraspecific vs. Interspecific Competition: Intraspecific involves competition within a single species, while interspecific involves competition across different species.
- Similarities in Predator/Prey and Parasitic Relationships: Both involve interactions where one organism benefits at the cost of another, yet the methods of obtaining benefit differ.
