Basics of Ecology

1 / 16

1. Which type of ecology deals with the study of how ecosystems respond to natural or human-induced disturbances?

Restoration ecology

Conservation ecology

Disturbance ecology

Behavioral ecology

2 / 16

2. Which term describes the ecological succession where an area with no soil and little life (like a newly formed volcanic island) begins to develop ecosystems?

Secondary succession

Pioneer succession

Primary succession

Climax succession

3 / 16

3. Which of the following would be studied under landscape ecology?

The behavior of a single bear

Interaction between two species of plants

The effect of urban sprawl on habitat fragmentation

The nutrient cycle in a pond

4 / 16

4. What is ‘r-strategy’ in the context of population ecology?

A strategy involving high reproductive rates with little investment in offspring care

A strategy involving low reproductive rates with heavy investment in offspring survival

A strategy focused on reducing competition through spatial distribution

A strategy aimed at maximizing the life span of individuals

5 / 16

5. In the context of ecological succession, what does ‘facilitation’ mean?

When early successional species make conditions more favorable for later species

When species compete for the same resources

When species evolve to occupy different niches

When an ecosystem reaches a stable, self-sustaining state

6 / 16

6. What is the final stable stage of ecological succession called?

Pioneer stage

Seral stage

Climax community

Stable stage

7 / 16

7. A community in ecology refers to:

All the populations of different species living together in a habitat

A group of individuals from the same species

The physical environment where organisms live

The total number of species in an ecosystem

8 / 16

8. The ‘Intermediate Disturbance Hypothesis’ suggests that:

Species diversity is highest at intermediate levels of disturbance

Ecosystems are most stable when disturbances are minimal

Frequent disturbances lead to higher species richness

No disturbance leads to the highest biodiversity

9 / 16

9. Synecology is the study of:

The ecology of individual organisms

The ecology of a single species

The relationships between different species in an ecosystem

The study of global ecological systems

10 / 16

10. What does ‘metapopulation dynamics’ study?

The movement of individuals between habitats

The genetic diversity within a single population

The interactions between populations of the same species distributed in spatially distinct patches

The effect of climate change on population sizes

11 / 16

11. “Ecological stoichiometry” examines:

The balance of chemical elements in ecological interactions

The physical layout of species in an ecosystem

The energy budget within an ecosystem

The carbon footprint of different ecosystems

12 / 16

12. Which type of symbiosis is characterized by one species benefiting at the expense of another?

Mutualism

Commensalism

Parasitism

Amensalism

13 / 16

13. What does the term ‘ecosystem resilience’ most closely refer to?

The ability of an ecosystem to return to its original state after a disturbance

The number of species an ecosystem can support

The rate at which energy is transferred through trophic levels

The diversity of genetic material within an ecosystem

14 / 16

14. Which ecological principle describes the idea that closely related species are less likely to coexist in the same ecological niche due to competition?

Competitive Exclusion Principle

Niche Partitioning

Principle of Resource Equivalence

Bergmann's Rule

15 / 16

15. The concept of ‘island biogeography’ mainly deals with:

The study of how species adapt to island conditions

The balance between immigration and extinction rates on islands

The evolution of island endemism

The geological processes that form islands

16 / 16

16. Ecosystem ecology would focus on:

Energy flow and productivity within ecosystems

The genetic variation within populations

The social structure within animal groups

The morphology of species

I’d have to examine with you here. Which is not one thing I usually do! I take pleasure in reading a post that may make folks think. Additionally, thanks for permitting me to comment!
