    What defines an ecosystem?

    It creates a functional unit of nature through interactions between organisms and their environment.

    What are the two main types of ecosystems?

    Natural ecosystems and artificial ecosystems.

    How do autotrophs differ from heterotrophs?

    Autotrophs produce their own food, while heterotrophs rely on others for food.

    What is the single channel energy flow model?

    Energy flows unidirectionally from green plants to herbivores and then to carnivores.

    What happens to energy in the universal energy flow model?

    Energy decreases at each trophic level due to loss as heat.

    How does a food chain differ from a food web?

    A food chain shows a linear flow, while a food web represents interconnected food chains.

    What does a pyramid of energy illustrate?

    It shows energy flow at each trophic level, always upright due to energy loss.

    What distinguishes producers from consumers?

    Producers create food from sunlight, while consumers depend on other organisms for food.

    What is a detritus food chain?

    It starts with dead organic matter and flows through microorganisms to predators.

    What is bio magnification?

    It is the increasing concentration of toxins in organisms at higher food chain levels.

    What is genetic diversity?

    It refers to the variation of genes within a species or population.

    What does ecosystem diversity encompass?

    It includes the variety of habitats and ecological processes within ecosystems.

    What defines a biodiversity hot spot?

    A region with significant biodiversity that is threatened by human activities.

    What is the difference between critically endangered and endangered species?

    Critically endangered species face an extremely high risk of extinction, while endangered species face a very high risk.

    What is a wildlife sanctuary?

    A protected area that preserves animals and plants from harm and promotes biodiversity.

    What was the goal of Project Tiger?

    To conserve Bengal tigers in their natural habitat and prevent their extinction.

    What are renewable energy resources?

    Resources that can be regenerated or recycled within a short time frame.

    What characterizes nonmetallic minerals?

    They lack metallic properties but are essential for various industries.

    What are metallic minerals?

    Minerals that contain metals and are good conductors of heat and electricity.

    What are the major natural resources?

    Forest, water, mineral, land, food, and energy resources.

    How are natural resources categorized?

    Into living (biotic) and non-living (abiotic) resources.

    What is the classification of minerals?

    Minerals are classified as metallic, non-metallic, energy, and precious minerals.

    What defines the Pyramid of Biomass?

    It shows the total dry matter at each trophic level.

    How does the Pyramid of Biomass differ in forests and ponds?

    Forests have an upright pyramid; ponds have an inverted pyramid.

    What is the consequence of energy loss in the Pyramid of Energy?

    Only 10% of energy passes to the next trophic level.

    What role do producers play in a food chain?

    They convert solar energy into food.

    What distinguishes consumers from producers?

    Consumers depend on other organisms for food.

    What happens during ammonification?

    Decomposers break down amino acids to produce ammonia.

    What is the primary function of decomposers in a food chain?

    They recycle nutrients back into the ecosystem.

    What defines a food web?

    It consists of interconnected food chains.

    How does the Grazing Food Chain differ from the Detritus Food Chain?

    Grazing starts with living plants; detritus starts with dead organic matter.

    What is the significance of the Y-shaped energy flow model?

    It shows the interaction between grazing and detritus food chains.

    What is nitrogen fixation?

    The conversion of atmospheric nitrogen into usable forms.

    What is the role of symbiotic bacteria in nitrogen fixation?

    They help legumes convert nitrogen into ammonia.

    What occurs during nitrification?

    Ammonia is oxidized to nitrite and then to nitrate.

    What is denitrification?

    The process of converting nitrates back to gaseous nitrogen.

    What is the first law of thermodynamics in relation to energy flow?

    Energy cannot be created or destroyed, only transformed.

    What happens to energy as it moves through trophic levels?

    It dissipates and decreases at each level.
