SPECIES

Which species is famously known as 'Congress grass'?

“Parthenium hysterophorus” for which species is famously known as 'congress grass'. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Ecological interpretation requires separating the immediate process from its broader consequence. A mechanism operating through physiology or behavior can scale up to alter survival, reproduction, abundance, distribution, and community structure. The remaining alternatives—“Eichhornia crassipes”, “Prosopis juliflora”, “Lantana camara”—refer to different states, proces

Why was Parthenium hysterophorus introduced to India?

“Accidental contaminant in imported wheat” for why was parthenium hysterophorus introduced to india. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. A sound explanation connects the stated pattern to a causal pathway and distinguishes it from alternatives that describe different levels of organization or different ecological processes. The remaining alternatives—“Ornamental plant”, “Medicinal purposes”, “Soil erosion control”—refer to different states, processes, or scales and therefore do not exp

Which invasive species is known as 'Congress grass'?

“Parthenium hysterophorus” for which invasive species is known as 'congress grass'. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Management outcomes depend on scale and context: suppressing abundance at one site does not guarantee regional eradication when dispersal reconnects treated and untreated populations. The remaining alternatives—“Eichhornia crassipes”, “Prosopis juliflora”, “Lantana camara”—refer to different states, processes, or scales and therefore do not express the same causal rel
