Population Ecology - APES

Front

What do J-Shaped curves represent in population ecology?

Back

J-Shaped curves represent exponential growth.

Front

How do you measure population density?

Back

Population density is measured by dividing the number of individuals living in a defined space by the area of the space.

Front

What type of competition occurs when two male giraffes fight over the same resource?

Back

Intraspecific Competition.

Front

What does the carrying capacity represent on a population growth graph?

Back

The carrying capacity is the maximum population size that an environment can sustain, often represented by a specific point on the graph.

Front

Which limiting factor is independent of the number of individuals in a population?

Back

Natural disasters.

Front

Define carrying capacity in the context of population ecology.

Back

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

Front

What is the difference between intraspecific and interspecific competition?

Back

Intraspecific competition occurs between individuals of the same species, while interspecific competition occurs between individuals of different species.

Front

What is a density-dependent factor?

Back

A density-dependent factor is a limiting factor whose effects on the population change as the population density changes, such as competition and predation.

What is a density-independent factor?

Back

A density-independent factor is a limiting factor that affects a population regardless of its density, such as natural disasters.

Front

Explain the concept of exponential growth in populations.

Back

Exponential growth occurs when a population increases by a constant proportion over time, leading to a rapid increase in size.
