Study Notes
Ecosystems
- Ecosystems include all living organisms (biotic factors) and their physical environment (abiotic factors).
- They provide stable climates, breathable air, and resources like food and materials, as well as protection.
- Biotic factors include living things like plants, animals, fungi, protists, archaea, and bacteria.
- Abiotic factors are non-living components such as chemicals, physical conditions, and resources that affect living organisms.
- Major abiotic factors include temperature, air, water, sunlight, humidity, and soil conditions.
- Terrestrial ecosystems are land-based communities, such as forests, grasslands, tundra, and deserts.
- Aquatic ecosystems are water-based communities, including freshwater and marine ecosystems.
- Freshwater ecosystems are bodies of water with low salt content, such as lakes, ponds, rivers, and wetlands.
- Marine ecosystems are saltwater environments, such as oceans and seas.
Estuaries, Mangroves, and Wetlands
- Estuaries are where freshwater mixes with saltwater.
- They support many marine species and protect coastal areas.
- Mangroves are coastal forests in tropical and subtropical regions.
- Mangroves have unique adaptations like prop roots and pneumatophores.
- They are biodiversity hotspots, absorbing carbon dioxide and supporting various species.
- Wetlands are covered by water or saturated with water, either seasonally or permanently, and have a variety of forms.
Types of Ecosystems
- Terrestrial ecosystems include forests, grasslands, tundra, and deserts.
- Aquatic ecosystems include freshwater and marine ecosystems.
- Marine ecosystems include coral reefs, which are underwater structures formed by coral skeletons, protecting coastlines.
- Freshwater ecosystems include ponds, lakes, rivers, and wetlands.
Artificial Ecosystems
- Artificial ecosystems are man-made ecosystems such as botanical gardens, orchards, aquariums, zoos, and urban areas.
- They are not self-sustaining and need human intervention.
- Urban areas are artificial ecosystems combining natural and human elements.
Food Chains and Trophic Levels
- A food chain depicts the transfer of energy and nutrients between organisms.
- Trophic levels represent the feeding positions in a food chain.
- Producers are at the bottom, followed by primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (apex predators).
- Decomposers break down dead matter and recycle nutrients.
- Grazing food chains begin with producers, while detritus food chains start with dead organic matter.
Nutrient Cycling
- Nutrient cycles are cyclic pathways where nutrients pass through different components of the environment.
- Four major cycles are the carbon, nitrogen, phosphorus, and water cycles.
- The carbon cycle involves the exchange of carbon between the atmosphere, oceans, land, and living organisms.
- The nitrogen cycle converts inert atmospheric nitrogen into usable forms for living organisms.
- The phosphorus cycle moves phosphorus through soil, water, plants, and animals.
- The water cycle involves the movement of water between the Earth's surface and atmosphere.
Ecological Pyramids
- Ecological pyramids are graphical representations of the relationship between organisms in different trophic levels.
- These include pyramids of energy, biomass, and numbers.
- Pyramids of energy illustrate the flow of energy from one trophic level to the next.
- Pyramid of biomass shows the total biomass present at each level.
- Pyramid of numbers shows populations in different trophic levels.
