Unit 3 Populations Review

Front

Organisms that have inherited traits that give them an advantage in their natural environment are said to be...

Back

adapted to that environment.

Front

Temperature, air/water currents, sunlight, soil type, rainfall, and available nutrients are all examples of...

Back

abiotic factors.

Front

As resources in a population become less available (limited), population growth will...

Back

slow down as it reaches carrying capacity.

Front

This organism (that is not a stick) has evolved colors and external structures to avoid being eaten by a predator. What sort of community interaction is occurring here?

Back

mimicry.

Front

What type of population growth graph is shown here?

Back

logistic growth.

Front

Define 'carrying capacity' in the context of populations.

Back

The maximum number of individuals of a species that an environment can support sustainably.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living physical and chemical elements.

Front

Explain the concept of 'natural selection'.

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is 'population density'?

Back

Population density is the number of individuals per unit area or volume.

Front

Describe 'mutualism' in ecological terms.

Back

Mutualism is a type of symbiotic relationship where both species benefit from the interaction.
