    Study Notes

    Pesticides

    • Organophosphate and carbamate pesticides are highly toxic and persistent to sensitive organisms.
    • The trade name for glyphosate, the most heavily used herbicide in the United States, is Roundup.
    • Inorganic pesticides are compounds made from toxic elements like sulfur, copper, arsenic, and mercury.

    Genetically Modified Organisms (GMOs)

    • 'Roundup-ready' soybeans and corn varieties are genetically modified to tolerate glyphosate, a herbicide.

    Synthetic Pesticides

    • Synthetic pyrethroid is among the most abundantly used synthetic pesticides.

    Ecosystem and Community Interactions

    What is an Ecosystem?

    • An ecosystem consists of living (biotic) and non-living (abiotic) components interacting with each other.

    Community and Population

    • A community is a group of different species that live together in a specific area.
    • A population is a group of individuals of the same species that live in a specific area.

    Abiotic Factors

    • Abiotic factors in an ecosystem include non-living components such as light, temperature, water, soil, and air.

    Community Interactions

    • There are three major types of community interactions: predation, competition, and symbiosis.
    • Predation is a type of community interaction where one species (predator) feeds on another species (prey).
    • Competition is a type of community interaction where different species compete for the same resources such as food, water, and light.
