Meaning

Rationale: Eduard Suess coined the term 'Biosphere' in 1875 in his book 'Die Entstehung der Alpen', though Vernadsky later developed it into a comprehensive biogeochemical system.

Rationale: An ecotone is a transitional zone where two different ecosystems meet and integrate, often exhibiting edge effect and high species richness.

Rationale: The biosphere is not a separate layer but extends into the lower atmosphere, upper lithosphere, and almost all of the hydrosphere where life exists.

Rationale: Lindeman's 10% law states that roughly 90% of energy is lost as heat and metabolic processes at each trophic transfer, leaving only about 10% for the next level.

Rationale: Russian geochemist Vladimir Vernadsky formulated the theory of the biosphere in his 1926 book 'Biosfera', emphasizing living organisms as geological agents.

Rationale: Ernst Haeckel coined the term ecology in 1866 to describe the economy of nature and the total relations of animals to their inorganic and organic environments.

Rationale: Autecology focuses on the ecological study of a single species in relation to its environment, whereas synecology deals with communities.

Rationale: Carrying capacity represents the environmental limit where resource availability matches the population demands of a specific species.

Rationale: Biomagnification refers to the upward concentration of persistent toxins along the food chain, affecting top carnivores severely.

Rationale: An ecological niche defines not just where an organism lives (habitat) but what it does, how it gets food, and how it interacts with other species.

Rationale: Edaphic factors pertain to soil characteristics such as pH, texture, organic matter content, and moisture retention capacity.

Rationale: Primary succession starts on bare, lifeless substrates (like volcanic rock or newly formed dunes), lacking pre-existing soil or organic matter.

Rationale: Homeostasis refers to the self-regulating properties of ecosystems that allow them to resist change and recover from disruptions.

Rationale: Frederic Clements proposed that plant succession always culminates in a single climatic climax community determined strictly by regional climate.

Rationale: Solar radiation represents an abiotic (non-living) factor, whereas plants, bacteria, and herbivores are biotic components.

Rationale: The biosphere encompasses all living matter on Earth combined with their respective physical environments, often synonymous with ecosphere.

Rationale: Temperature and precipitation gradients are the two master climatic controls dictating the global distribution of major terrestrial biomes.

Rationale: The edge effect describes the increased biodiversity and population density often observed in transitional ecotones due to overlapping niches.
