  1. What is the study of the relationships between living organisms and their environment?
    • Geology
    • Ecology
    • Biology
    • Zoology
    The correct answer is Ecology.
    Ecology is a branch of biology that studies the interactions among organisms and their biophysical environment.
  2. What is the term for a group of organisms of the same species living in the same area?
    • Ecosystem
    • Community
    • Population
    • Biosphere
    The correct answer is Population.
    A population consists of individuals of the same species living in a specific area and interacting with each other.
  3. Which of these is not an abiotic factor in an ecosystem?
    • Soil
    • Light
    • Temperature
    • Predation
    The correct answer is Predation.
    Abiotic factors are non-living components of an ecosystem, such as temperature, soil, and light. Predation is a biotic factor, as it involves living organisms.
  4. What is the process by which plants convert sunlight into usable energy?
    • Photosynthesis
    • Decomposition
    • Transpiration
    • Respiration
    The correct answer is Photosynthesis.
    Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen.


  1. What is the term for a close, long-term interaction between two different species?
    • Competition
    • Mutualism
    • Symbiosis
    • Predation
    The correct answer is Symbiosis.
    Symbiosis is a close, long-term relationship between two different species, which can be beneficial, harmful, or neutral to one or both organisms.
  2. What is the term for the maximum number of individuals of a species that an environment can support?
    • Population density
    • Ecological niche
    • Biodiversity
    • Carrying capacity
    The correct answer is Carrying capacity.
    Carrying capacity is the maximum number of individuals of a species that a specific environment can support, based on available resources and environmental conditions.
  3. What is the term for the role an organism plays in its environment?
    • Ecological niche
    • Trophic level
    • Habitat
    • Food chain
    The correct answer is Ecological niche.
    An ecological niche refers to the role an organism plays in its environment, including its habitat, diet, and interactions with other organisms.
  4. Which of these is not a type of symbiosis?
    • Parasitism
    • Mutualism
    • Commensalism
    • Predation
    The correct answer is Predation.
    Predation is a type of interaction between species, but it is not a form of symbiosis. Symbiosis includes mutualism, commensalism, and parasitism.
  5. What is the term for a group of different species living in the same area?
    • Community
    • Biosphere
    • Population

    • Ecosystem
    • Biodiversity
    • Biome
    • Habitat
    The correct answer is Biodiversity.
    Biodiversity refers to the variety of life on Earth, including the diversity of species, genes, and ecosystems.
  2. What is the process by which water is lost from plants through tiny pores called stomata?
    • Evaporation
    • Transpiration
    • Precipitation
    • Condensation
    The correct answer is Transpiration.
    Transpiration is the process by which water is lost from plants through tiny pores called stomata, mainly on the underside of leaves.
  3. What is the term for the process by which nutrients are returned to the soil after organisms die and decompose?
    • Respiration
    • Nutrient cycling
    • Photosynthesis
    • Transpiration
    The correct answer is Nutrient cycling.
    Nutrient cycling is the process by which nutrients are returned to the soil after organisms die and decompose, ensuring that nutrients are available for future generations of organisms.
  4. Which of the following is not a type of ecosystem?
    • Desert
    • Tundra
    • Volcano
    • Rainforest
    The correct answer is Volcano.
