In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'. Evolutionary processes give rise to biodiversity in every (1)/ level of biological organisation, including the level of (2)/ species, individual organisms, and molecules. (3)/ No error (4)

Identifying the Grammar Error in Biodiversity Sentence
Let's carefully examine the sentence provided and break it down into its numbered parts to find any potential errors.
The sentence is: "Evolutionary processes give rise to biodiversity in every (1)/ level of biological organisation, including the level of (2)/ species, individual organisms, and molecules. (3)/ No error (4)"
Analysis of Each Part
- Part (1): "Evolutionary processes give rise to biodiversity in every"
- Part (2): "level of biological organisation, including the level of"
- Part (3): "species, individual organisms, and molecules."
- Part (4): "No error"
Detailed Error Analysis
We need to look for grammatical issues, awkward phrasing, or incorrect word usage in each part.
- Part (1): "Evolutionary processes give rise to biodiversity in every". The phrase "give rise to" is a correct idiom meaning 'cause' or 'lead to'. "Biodiversity" is the variety of life, which is a singular concept. The issue here lies with the preposition "in" used with "every level". When referring to the scale or position within a hierarchy or classification system like "levels of biological organisation", the preposition "at" is typically used, not "in". Biodiversity exists at the species level, at the ecosystem level, at the molecular level, etc. Therefore, "in every level" is grammatically incorrect in this context; it should be "at every level".
- Part (2): "level of biological organisation, including the level of". This part introduces the different levels. "level of biological organisation" is correct phrasing. "including the level of" correctly sets up a list of specific levels. This part contains no error.
- Part (3): "species, individual organisms, and molecules." This lists examples of the levels. While the phrase "including the level of" applies to these items, listing "individual organisms" alongside "species" and "molecules" as 'levels' might be considered slightly unconventional phrasing depending on the specific classification system, but it is understandable in the context of discussing the scale at which biodiversity can be observed. The list itself is grammatically structured correctly after "including the level of". This part contains no grammatical error in its structure.
Based on the analysis, the error is located in Part (1) due to the incorrect use of the preposition "in" instead of "at" when referring to biodiversity existing on different scales or levels of biological organisation.
Identifying the Part with Error
The error is in the phrase "in every" in the first part of the sentence.
Corrected Sentence
The corrected sentence would be: "Evolutionary processes give rise to biodiversity at every level of biological organisation, including the level of species, individual organisms, and molecules."
Conclusion
The part of the sentence that contains the error is part (1).
Revision Table: Prepositions of Place/Position
Understanding prepositions like 'in' and 'at' is key for accuracy.
| Preposition | Common Usage Examples |
|---|---|
| In | Inside a container/space (in the box), within a large area (in the city), a period of time (in the morning), language/subject (in English). |
| At | A specific point (at the corner), a location (at the bus stop), an event (at the party), a level or position on a scale (at a high level, at sea level, at every level). |
Additional Information: Biodiversity Levels and Evolutionary Processes
Biodiversity, or biological diversity, refers to the variety of life on Earth at all its levels, from genes to ecosystems. Evolutionary processes, such as mutation, gene flow, genetic drift, and natural selection, are the fundamental mechanisms that generate and maintain this vast array of life.
- Molecular Level: Diversity in genes and proteins within populations.
- Organism Level: Variation among individual organisms.
- Species Level: The variety of different species.
- Ecosystem Level: The variety of habitats, communities, and ecological processes.
Evolutionary change occurs over time, leading to new genetic variations, the formation of new species, and changes in ecosystems, thereby constantly shaping and reshaping biodiversity across all these levels.
