The correct Answer is:
To solve the question regarding which statement about biodiversity is incorrect, we will analyze each statement one by one. ### Step 1: Analyze Statement I **Statement I:** Species diversity is highest in poles and decreases towards tropics. - **Analysis:** This statement is incorrect. In reality, species diversity is highest in the tropics and decreases towards the poles. The tropics have favorable climatic conditions, including adequate rainfall and warm temperatures, which support a greater variety of species. In contrast, polar regions have harsh climates that limit biodiversity. ### Step 2: Analyze Statement II **Statement II:** Stable communities show more productivity. - **Analysis:** This statement is correct. Stable communities tend to have established relationships and fewer disturbances, which allows for higher productivity. The absence of frequent changes or disturbances enables these communities to maintain their productivity over time. ### Step 3: Analyze Statement III **Statement III:** Sacred groves are a type of ex situ conservation. - **Analysis:** This statement is incorrect. Sacred groves are actually a form of in situ conservation, as they are preserved in their natural habitat. Ex situ conservation involves removing species from their natural habitats and protecting them in controlled environments, which is not the case for sacred groves. ### Step 4: Analyze Statement IV **Statement IV:** More solar energy available in tropics contributes to its higher productivity. - **Analysis:** This statement is correct. The tropics receive more solar energy, which, along with favorable climatic conditions, leads to higher productivity in these regions. The abundance of sunlight supports photosynthesis, which is crucial for plant growth and, consequently, the entire ecosystem. ### Conclusion Based on the analysis: - **Incorrect Statements:** I and III - **Correct Statements:** II and IV Thus, the correct answer to the question "Which of the following is incorrect regarding biodiversity?" is that Statements I and III are incorrect. ### Final Answer The incorrect statements regarding biodiversity are: - I. Species diversity is highest in poles and decreases towards tropics. - III. Sacred groves are a type of ex situ conservation.

Which of the following is a reason for the greater biological diversity of tropical regions ? (a) Tropical latitudes have remained almost undisturbed for millions of years. (b) Tropical environments are less seasonal, relatively more constant and predictable. (c) More solar energy is available in the tropics, resulting in high productivity. (d) All of these

What is so special about tropics that might account for their greater biological diversity? a. Unlike temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification. b. Temperate environments, unlike tropical ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity. c. There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity.

In the tropical rainforest, the majority of trees have showy animal-pollinated flowers. In temperate forests the majority of trees are wind pollinated. Which factors best explain these contrasting patterns ? (i) Wind is rare in tropical forests. (ii) Because of high species diversity in the tropics, individuals of trees species are often widely separated making wind an inefficient means of pollen dispersal. (iii) More opportunities for coevolved mutualisms exist in tropical forests because of the high diversity of animal species. (iv) Trees in tropical forests are mostly evergreen and year-round leaf canopies impede pollen dispersal by wind. (v) Flowering in tropical forests occurs over a short period of time when wind is absent. (a) (i) , (ii) and (v) (b) (i),(iii) and (v) (c) (ii), (iii) and (iv) (d) (ii) and (iv)
