1
In many species, such as honeybees, the 'waggle dance' is a form of communication that conveys information about the direction and distance to a food source. This is an example of:
-
A
Perfect information in a competitive market
-
B
Asymmetric information
-
C
Signaling to reveal quality
-
D
Information economics and resource discovery
2
The optimal foraging theory suggests that predators will choose to consume prey that maximizes their net energy intake per unit time. For example, a lion might prioritize hunting zebras over wildebeest if zebras offer a better energy return for the effort involved. This illustrates the concept of:
-
A
Diminishing marginal returns
-
B
Price discrimination
-
C
Rational choice and cost-benefit analysis
-
D
Externalities in predation
3
When a group of meerkats cooperate to forage and watch for predators, with some individuals acting as sentinels while others search for food, they exhibit:
-
A
A monopoly on foraging grounds
-
B
Positive externalities from cooperation
-
C
The tragedy of the commons
-
D
Rent-seeking behavior
4
The concept of 'niche partitioning' in ecosystems, where different species evolve to utilize slightly different resources or habitats to avoid direct competition, is analogous to:
-
A
Perfect price discrimination by a monopolist
-
B
Product differentiation and market segmentation
-
C
Collusion in a cartel
-
D
Price ceilings in a regulated market
5
The red deer's dominance hierarchy, where stronger individuals monopolize access to mating opportunities and prime foraging areas, demonstrates:
-
A
Consumer surplus
-
B
Producer surplus and market power
-
C
The law of demand
-
D
Free rider problems
6
The phenomenon of 'mimicry' in nature, where a harmless species evolves to resemble a dangerous one (e.g., hoverflies resembling wasps), can be seen as a form of:
-
A
Price signaling
-
B
Adverse selection
-
C
Moral hazard
-
D
Information asymmetry and strategic signaling
7
When a river ecosystem is polluted by a factory upstream, the cost of the pollution (e.g., damaged fishing, health issues) that is borne by others is a classic example of:
-
A
A public good
-
B
A positive externality
-
C
A negative externality
-
D
Rivalry in consumption
8
The idea that limited resources, such as freshwater or grazing land, can be depleted by over-consumption by individuals acting in their own self-interest is known as:
-
A
The law of supply
-
B
The tragedy of the commons
-
C
Comparative advantage
-
D
Network externalities
9
The territorial defense of a food source by an animal, where it expends energy to prevent others from accessing its resources, represents an effort to establish:
-
A
Economies of scale
-
B
Property rights and exclusivity
-
C
Natural monopoly
-
D
Barriers to entry
10
In the study of whale migration, the significant energy expenditure for long journeys to breeding grounds suggests a high 'opportunity cost' of not feeding. This relates to:
-
A
Diminishing marginal utility
-
B
The concept of trade-offs and opportunity cost
-
C
Perfect substitutes
-
D
Elasticity of demand
11
The diversification of crops by farmers to reduce the risk of crop failure due to pests or disease is an application of the economic principle of:
-
A
Monopolistic competition
-
B
Risk management and portfolio diversification
-
C
Price floors
-
D
Bundling
12
The evolution of symbiotic relationships, where two species benefit from each other (e.g., clownfish and anemones), can be viewed as a microeconomic scenario where mutual benefit arises from:
-
A
Zero-sum games
-
B
Positive-sum interactions and specialization
-
C
Predatory pricing
-
D
Market failure
13
The phenomenon where a species' population growth is limited by the carrying capacity of its environment, leading to slower growth as resources become scarce, reflects:
-
A
Increasing returns to scale
-
B
Diminishing marginal returns to resources
-
C
Perfect competition
-
D
Price leadership
14
When a large predator species, like wolves, is reintroduced into an ecosystem and their presence influences the behavior and population dynamics of prey species (e.g., elk), it demonstrates:
-
A
Market power of prey
-
B
Top-down control and ecosystem services
-
C
Price gouging
-
D
Consumer sovereignty
15
