Ecology Quiz

What is ecology the scientific study of?

• The classification of living organisms

• The interactions between organisms and the environment

• The genetic makeup of organisms

• The history of life on Earth

Which of the following factors can affect the population distribution of a species?

• Food availability

• Pathogens

• Both A and B

• None of the above

How can interactions in ecology be organized?

• In a linear fashion

• Randomly

• In a hierarchy that ranges from individual organisms to the planet

• Based on the size of the organisms

What does organismal ecology primarily study?

• The effect of interspecific interactions on community structure

• The community of organisms in an area and the physical factors with which they interact

• How an organism's structure, physiology, and behavior meet environmental challenges

• The exchanges of energy, materials, and organisms across multiple ecosystems

What is the focus of population ecology?

• The effect of energy and materials on organisms across the biosphere

• Factors affecting population size over time

• The community of organisms in an area

• The exchanges of energy and materials across multiple ecosystems

Community ecology examines the effects of what?

• Interspecific interactions on community structure and organization

• Organismal structure and behavior in an environmental context

• Population size and its changes over time

• Energy flow and chemical cycling between organisms and the environment

What is the main emphasis of ecosystem ecology?

• The study of organismal structure, physiology, and behavior

• The effect of interspecific interactions on community structure

• Energy flow and chemical cycling between organisms and the environment

• The exchanges of energy and materials across landscapes

Landscape ecology focuses on which of the following?

• The global sum of all the planet's ecosystems

• The effect of interspecific interactions on community structure

• The exchanges of energy, materials, and organisms across multiple ecosystems

• Factors affecting population size over time

What does global ecology examine?

• The effect of energy and materials on organisms across the biosphere

• The community of organisms in an area and their physical interactions

• The structure and behavior of individual organisms

• The size and distribution of populations over time

What are the four major physical components of climate?

• Temperature, humidity, vegetation, and soil type

• Temperature, precipitation, sunlight, and wind
