Systems ecology

1. Systems ecology is an interdisciplinary field that focuses on the interactions and relationships between organisms and their environment. It studies the flow of energy, nutrients, and information within ecosystems to understand how they function as complex, interconnected systems. By examining the interdependence of living and non-living components in an ecosystem, systems ecology seeks to develop a holistic understanding of ecological processes and dynamics. This approach helps researchers and policymakers address environmental challenges such as climate change, habitat destruction, and species extinction by considering the interconnectedness of natural systems and the impact of human activities on them.

How do human activities affect ecological systems?

A) They always improve the balance in ecosystems
B) They can disrupt and degrade ecosystems through pollution, deforestation, and overfishing
C) They have no impact on ecological systems
D) They make ecosystems more resilient and adaptable

2. What is the goal of sustainability in systems ecology?

A) To maximize short-term profits regardless of ecological consequences
B) To deplete resources as quickly as possible
C) To avoid studying ecological systems
D) To maintain ecological balance and preserve resources for future generations

3. What is resilience in the context of systems ecology?

A) The ability of an ecosystem to absorb and recover from disturbances
B) The speed of ecosystem changes
C) The fragility of an ecosystem
D) The size of the ecosystem

4. How does climate change impact ecological systems?

A) Climate change has no impact on ecological systems
B) It can alter habitats, disrupt ecosystems, and lead to species extinction
C) Climate change only affects human populations
D) Climate change always benefits ecological systems

5. What does the carrying capacity of an ecosystem refer to?

A) The number of trophic levels in an ecosystem
B) The maximum population size that the environment can sustain indefinitely
C) The number of keystone species in an ecosystem
D) The annual rainfall in an ecosystem

6. What is a biogeochemical cycle in an ecosystem?

A) The seasonal climate changes
B) The size of the population in an ecosystem
C) The migration patterns of birds in an ecosystem
D) The cycling of elements like carbon, nitrogen, and phosphorus between living organisms and the environment

7. How do disturbances like wildfires or hurricanes affect ecological systems?

A) Disturbances only impact human populations
B) Disturbances have no impact on ecological systems
C) They can have both immediate and long-term impacts on ecosystem structure and function
D) Disturbances always benefit ecological systems

8. What is the role of decomposers in nutrient cycling in ecosystems?

A) Decomposers consume all primary producers in an ecosystem
B) Decomposers break down organic matter, returning nutrients to the soil for primary producers
C) Decomposers produce oxygen for other organisms in the ecosystem
D) Decomposers compete with primary consumers for food
