Study Notes
Ecology and Its Components
- Ecology: Focuses on the interactions between organisms and their environments.
- Biosphere: The global sum of all ecosystems, encompassing land surfaces, the atmosphere, and bodies of water.
- Atmosphere: The layer of gases enveloping Earth, extending from the surface into space.
- Hydrosphere: Encompasses all water bodies, including oceans, lakes, rivers, and ground water.
Ecosystems and Biomes
- Biomes: Major ecological areas characterized by specific climate conditions and life forms, including aquatic, forest, grassland, and wetland environments.
- Ecosystem: A smaller, localized community within a biome where biotic (living) and abiotic (non-living) components interact.
Living and Non-Living Factors
- Biotic Factors: Living organisms such as plants (flora) and animals (fauna) within an ecosystem.
- Abiotic Factors: Non-living components affecting ecosystems, including temperature, water, and soil nutrients.
Population Dynamics
- Community: A collection of different species populations inhabiting a shared area.
- Population: A group of individuals of the same species living in a defined space.
- Organism: An individual entity capable of living and reproducing as part of its population.
Trophic Levels and Energy Flow
- Producers: Organisms, primarily plants, that create food through photosynthesis, forming the base of food chains.
-
Consumers: Organisms that obtain energy by consuming other organisms, categorized into:
- Primary Consumers: Herbivores that feed solely on plants.
- Secondary Consumers: Omnivores and carnivores that eat both plants and animals.
- Detritivores: Organisms that feed on decaying organic matter.
Ecological Interactions
- Habitat: The natural environment that supports a species either permanently or temporarily.
- Niche: The role or function of an organism within its habitat, including its interactions and behaviors.
- Mutualism: A type of symbiosis where both species benefit from the relationship.
- Commensalism: A relationship in which one species benefits while the other is neither helped nor harmed.
- Competition: When organisms vie for limited resources such as food, space, or mates.
- Predation: The act of one species hunting and killing another for sustenance.
Nutrient Cycling and Ecosystem Changes
- Nutrient Cycling: The movement and transformation of nutrients within ecosystems, crucial for sustaining life.
- Nutrient: Essential chemical substances necessary for growth, reproduction, and survival.
- Food Chain: A linear model illustrating the transfer of energy between organisms.
- Ecological Succession: A gradual change in ecosystem composition leading to a stable climax community over time.
- Climax Community: A stable ecological community that has reached a predictable state following succession.
Environmental Management and Sustainability
- Ecosystem Management: Human efforts to oversee and balance organism interactions with their environments.
- Sustainability: The responsible use and conservation of resources to maintain ecological equilibrium long-term.
