Semester 1 APES Review

Front

What is a population in ecological terms?

Back

A population refers to the total number of individuals of a particular species living in a specific area at a given time.

Front

What biome is characterized by plants and grasses, but no trees?

Back

Grassland is a biome characterized by vast open spaces dominated by grasses and few trees.

Front

What type of growth is characterized by a rapid increase in population size?

Back

Exponential growth is a type of growth where the population size increases rapidly over time, often represented by a J-shaped curve.

Front

What happens to a population when it exceeds the carrying capacity of its ecosystem?

Back

When a population exceeds the carrying capacity, it typically starts to die off to return to sustainable levels.

Front

What type of society is represented by a population pyramid with a wide base and a narrow top?

Back

An agricultural, undeveloped country (rapid growth) is represented by a population pyramid with a wide base and a narrow top.

Front

Define carrying capacity in an ecosystem.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

What is logistic growth?

Back

Logistic growth is a population growth model that shows how a population grows rapidly at first, then slows as it approaches the carrying capacity, forming an S-shaped curve.

Front

What is the predator-prey cycle?

Back

The predator-prey cycle describes the fluctuations in population sizes of predators and their prey, where the population of one affects the other.

Front

What is a biome?

Back

A biome is a large geographical area characterized by specific climate conditions, plants, and animals.

Front

What is the difference between a developed and developing country in terms of population growth?

Back

Developed countries typically have stable or declining population growth, while developing countries often experience rapid population growth.
