Study Notes

Ecosystem Relationships

Predator: Hunts other animals for food, playing a crucial role in controlling prey populations.
Consumer: Organisms that rely on other organisms for energy, essential for ecosystem balance.
Symbiosis/Symbiotic Relationships: Involve long-term interactions between two species with at least one benefiting; essential for ecological dynamics.
Herbivore: Animals that exclusively consume plants, forming the primary consumers in food chains.
Prey: Organisms hunted, killed, and consumed by predators; vital for predator survival.
Commensalism: A type of symbiotic relationship where one species benefits and the other remains unaffected, exemplifying ecological interdependence.
Omnivore: Organisms that consume both plants and animals, playing a versatile role in food webs.
Mutualism: Interaction where both species benefit, such as bees pollinating flowers, promoting biodiversity.
Parasitism: Relationship where one species benefits at the expense of the other, often harming the host species.
Food Chain: Illustrates the flow of energy through various organisms; fundamental for understanding ecosystem interactions.
Producer: Organisms like plants that produce their food through photosynthesis, forming the base of food chains.
Ecosystem: Comprises living (biotic) and nonliving (abiotic) components interacting in a specific environment.
Community: Encompasses all populations of different species living in a shared environment, contributing to ecosystem dynamics.
Population: Refers to all individuals of a single species in a given area, important for studying species distribution and health.
Individual: Defines a single organism, representing the basic unit of ecological studies.
Biotic: Includes all living organisms, dead matters, and organic products within an ecosystem.
Abiotic: Pertains to non-living factors such as climate, soil, water, and minerals that influence ecosystems.
Primary Consumer: Organisms that consume producers; can be herbivores or omnivores, serving as a crucial link in energy transfer.
Secondary Consumer: Organisms that eat primary consumers; may include carnivores and omnivores, impacting population dynamics.
Tertiary and Quaternary Consumers: Higher-level consumers, with tertiary eating secondary consumers and quaternary feeding on tertiary, illustrating complex food webs.
Energy Pyramid: Graphical representation that demonstrates energy transfer efficiency through trophic levels, highlighting energy loss at each stage.
Oppositional Relationships: Negative interactions impacting both organisms involved, even if one appears to "win" due to resource acquisition, as it consumes energy and risks injury.
Predation: A straightforward form of interaction where one organism hunts and consumes another, shaping population dynamics.
Competition: Occurs when organisms vie for the same resources, leading to resource depletion and detrimental effects on both.
Intraspecies Competition: Competition within the same species, often for mates or territory, influencing evolutionary traits and behaviors.
Interspecies Competition: Competition between different species for shared resources, affecting biodiversity and niche differentiation.
Scavengers: Organisms that feed on dead animals, such as vultures, aiding in ecosystem nutrient cycling.
Decomposers: Microorganisms that break down waste and dead organisms, crucial for recycling nutrients and maintaining soil health.
