TESTED QUESTIONS WITH VERIFIED
ANSWERS COMPLETE STUDY SHEET
●● Who introduced the term 'environment' in Ecology?
Answer: Jacob Van Uerkal (1864-1944).
●● How is the environment defined in ecological terms?
Answer: The sum total of land, water, air, and interrelationships among
living organisms and humans.
●● What is the definition of the physical environment?
Answer: All the physical surroundings on Earth where living things exist
or the conditions they need to survive.
●● What constitutes the natural environment?
Answer: The sum total of living and non-living things occurring
naturally, including air, land, water, and living organisms.
●● What are abiotic components?
Answer: Non-living elements and factors of the environment essential
for supporting life.
,●● What is the atmosphere?
Answer: A blanket of gases around the Earth that protects it from
harmful ultraviolet rays and regulates temperature.
●● What percentage of Earth's water is found in oceans?
Answer: 97%.
●● What is the lithosphere?
Answer: The outer mantle of the solid Earth, consisting of minerals in
the Earth's crust and soil.
●● What is the role of soil in the environment?
Answer: Vital for plant growth, acts as a natural filter, and supports
ecosystems.
●● Why is sunlight considered a critical abiotic component?
Answer: It provides the primary source of energy for almost all life on
Earth through photosynthesis.
●● What are biotic components?
Answer: All living organisms that inhabit the Earth and interact with
each other and abiotic components.
, ●● What role do plants play in ecosystems?
Answer: They are autotrophic organisms that produce energy through
photosynthesis and form the foundation of the food chain.
●● What are the main functions of the environment?
Answer: Providing habitats, purifying air and water, regulating climate,
facilitating nutrient cycling, and supporting pollination.
●● What is the significance of energy flow in ecosystems?
Answer: It connects biotic and abiotic components and is essential for
the growth and regeneration of species.
●● What human activities can impact the environment?
Answer: Pollution, deforestation, habitat destruction, and climate
change.
●● What is the importance of sustainable practices?
Answer: To ensure a healthy environment for current and future
generations.
●● What are the key cycles that interrelate ecosystems?
Answer: Water cycle, carbon cycle, oxygen cycle, nitrogen cycle, and
energy cycle.
