    Study Notes

    Biotic and Abiotic Factors

    • Biotic factors are living things or things that came from living things
    • Abiotic factors are non-living things like temperature, humidity, precipitation, water availability, and soil type

    Biomes

    • Biome is a place where an organism lives
    • There are millions of different species of plants and animals in various locations on Earth
    • Examples of biomes include caves, tundra, forests, oceans, and deserts

    Atmosphere

    • The atmosphere is layers of gases surrounding Earth

    Biosphere

    • The biosphere is made up of all living things, living things that lived recently, or derived from living organisms

    Ecosystem

    • Ecosystem is a collection of biotic and abiotic factors that support life; they are complex
    • Ecologists use various terms to describe the parts of ecosystem
    • Individual: one type of living organism
    • Population: many of one type of organism
    • Community: many different types of organisms
    • Biome = many ecosystems

    Keystone Species

    • Keystone species control or modify the ecosystem's population of other species

    Consumers

    • Consumers cannot produce their own food; they need to eat plants or animals for energy

    Producers

    • Producers produce their own food (e.g., trees, shrubs, grass, algae, lichen, seaweed, and some bacteria)

    Ecological Pyramid

    • Shows how energy is transferred from one organism to another
    • The bottom shows producers
    • The top shows top carnivores/predators

    Competition

    • Competition occurs when individuals vie for limited resources

    Limiting Factors

    • Limiting factors are biotic or abiotic factors that restrict the size of a population

    Food Web and Food Chain

    • Food web is a complex network of interconnecting food chains
    • Food chain shows how matter and energy transfer between organisms

    Carrying Capacity

    • Carrying capacity is the maximum population size a given environment can support consistently before resources are depleted.
    • Abiotic factors in ecosystems determine carrying capacity

    Biogeochemical Cycles

    • These cycles show the movement of organisms and their nutrients in ecosystems

    Carbon Cycle

    • The carbon cycle describes how carbon atoms continuously travel between the atmosphere, Earth, and living organisms

    Nitrogen Cycle

    • The nitrogen cycle shows how nitrogen moves through various spheres of the environment

    Eutrophication

    • Eutrophication is the process where a body of water becomes overly enriched with nutrients, leading to the growth of simple plants.

    Invasive Species

    • Invasive species outcompete natural predators or encounter less threats in their new ecosystem. This can lead to population booms.

    Primary Succession

    • Primary succession is the formation of new ecosystems
    • Pioneer species (like lichen) modify rock into soil over many years
    • Takes a long time (hundreds of years) to reach an ecosystem equilibrium

    Secondary Succession

    • Secondary succession occurs after a significant disruption like fire or flood
    • Existing soil remains, and pioneer species quickly return the ecosystem to its prior state
    • Takes less time (50-200) years compared to primary succession

    Species

    • Species are groups of organisms capable of interbreeding naturally
    • Species represent the largest possible gene pool

    Sustainability

    • Sustainability is the ability of something to last

    Parasitism

    • One organism benefits while the other is harmed

    Mutualism

    • Both organisms benefit

    Predation

    • One organism hunts and kills another for food

    Commensalism

    • One organism benefits, with no impact on the other

    Decomposers

    • Decomposers break down dead organisms, recycling nutrients back into the ecosystem (e.g. bacteria and fungi)

    Optimum Range

    • Optimum range are the ideal conditions for organisms, and processes operate most effectively

    Biodiversity

    • Biodiversity measures the variety of life forms within a habitat or on Earth, including different species, ecosystems, and genotypic variations
