Which one or more of the following would make a plant community more susceptible to invasion by exotic plants?
Show Hint
- Anthropogenic influx of nutrients
- Decline in density of a dominant species due to disease
- Arrival of a highly competitive exotic species
- Absence of suitable pollinators for an invading species
The Correct Option is A, B, C
Solution and Explanation
Step 1: Evaluate Anthropogenic Influences.
An influx of nutrients can disrupt native plant communities, creating conditions favorable for invasive species that can exploit these resources more effectively than native species.
Step 2: Consider the Impact of Disease on Dominant Species.
A decline in a dominant species due to disease can create gaps in the ecosystem, reducing competitive pressures and allowing invasive species to establish more easily.
Step 3: Assess the Impact of Competitive Exotic Species.
The arrival of a highly competitive exotic species can directly challenge native species for resources, leading to changes in the community structure and potentially displacing native species.

- The table below describes the number of tree species in a forest whose seeds are dispersed by large or small animals, and whether they are insect or wind pollinated. In the past, seed dispersers and pollinators were abundant in this forest. Now, there are very few large animal dispersers, but the number of small animal dispersers has not changed. There are also very few insect pollinators in this forest. Which one or more of the following inferences about trees in the forest can be drawn from these changes in seed dispersers and pollinators?
- In a grassland (P), there are 8 plant species with a similar number of individuals of each species. In another grassland (Q), there are 12 species with uneven abundances. Which one of the following statements about the Shannon’s diversity index of P and Q is correct?

- An organization allows its employees to work independently on consultancy projects but charges an overhead on the consulting fee.
The overhead is 20% of the consulting fee if the fee is up to ₹5,00,000.
For higher fees, the overhead is ₹1,00,000 plus 10% of the amount by which the fee exceeds ₹5,00,000.
The government charges a Goods and Services Tax (GST) of 18% on the total amount (i.e., the consulting fee plus the overhead).
An employee of the organization charges this entire amount — that is, the consulting fee, overhead, and tax — to the client.
If the client cannot pay more than ₹10,00,000, what is the maximum consulting fee that the employee can charge?
