The place where an organism lives

The role an organism plays in an ecosystem

A community of interacting populations

A fundamental niche is:

The potential role an organism could play without competition

The niche an organism actually occupies

The habitat where an organism lives

The environment where no organisms can survive

No tolerance for environmental change

How do autotrophs obtain energy?

From the sun or chemical compounds

The energy transfer between species

The population size of an ecosystem

What is the difference between a food chain and a food web?

A food web shows overlapping food chains, while a food chain shows one pathway

A food chain shows overlapping feeding relationships, while a food web does not

A food chain is more complex than a food web

A food web only shows herbivores and omnivores

What law states that energy cannot be created or destroyed, only transferred?

The First Law of Thermodynamics

The Law of Conservation of Energy

The Second Law of Thermodynamics

The Law of Conservation of Matter

A relationship where both organisms benefit

A relationship where one organism benefits and the other is harmed

A relationship where one organism benefits and the other is unaffected

A relationship where both organisms are harmed

An example of parasitism is:

A tree providing shade for a plant

Which of the following describes a keystone species?

A species that has no interactions with other organisms

What are pioneer species?

The first organisms to inhabit barren environments

The last species to colonize an area

Primary succession begins:

In areas where there is no soil

A small population of organisms

A single species living in an area

A chaparral biome is typically found:

In hot and dry areas with mild winters

What is the difference between weather and climate?

Weather is daily, while climate is over a long period

Weather is long-term, climate is short-term

Climate changes every day, weather stays the same

Climate does not affect ecosystems

The ability of surfaces to reflect sunlight

The ability of a surface to absorb heat

The warming of the Earth's surface

The cooling of the Earth's surface

If Earth's albedo increases, what effect would this have on the planet?

It would decrease the temperature of the oceans

What do climatograms display?

Temperature and rainfall over time

Soil composition and biodiversity

Biome boundaries and their transitions

Generalists are organisms that:

Can easily adapt to a wide range of conditions

Have a narrow range of tolerance

Thrive in very specific conditions

Are highly specialized in their niches

Which of the following is an example of commensalism?

A bird building a nest in a tree

An indicator species is:

A species that responds to environmental changes

A species that stabilizes ecosystems

A species that is unaffected by environmental changes

A species that consumes other species

What is primary succession?

The development of an ecosystem where there is no soil

The gradual replacement of one species by another

The re-establishment of an ecosystem after a disturbance

The final stage of ecological succession
