U4 Final Review - Populations and Ecosystem Dynamics

Front

What is the formula to calculate growth rate in a population?

Back

Growth Rate = Birth Rate - Death Rate + Immigration Rate - Emigration Rate

Front

What is a limiting factor in an ecosystem?

Back

A biotic or abiotic resource that causes population size to decrease.

Front

How does the human population grow?

Back

The human population is growing exponentially.

Front

What is the definition of a population in ecology?

Back

All of the organisms of a species in a given environment.

Front

What contributes to exponential growth in a population?

Back

Less competition among individuals.

Front

Define carrying capacity.

Back

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

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 components.

Front

What is the significance of immigration in population dynamics?

Back

Immigration increases the population size by adding new individuals.

Front

What role do resources play in population growth?

Back

Resources such as food, water, and shelter are essential for population growth; limited resources can lead to decreased growth.

Front

What is exponential growth?

Back

A growth pattern where the population size increases rapidly over time, often represented by a J-shaped curve.
