Population Ecology

Front

What is immigration in population ecology?

Back

Immigration refers to the movement of individuals into a population from other areas, increasing the population size.

Front

What percentage of energy do herbivores receive from plants in a food web pyramid?

Back

Herbivores receive only 10% of the energy stored in plants.

Front

What is population dispersion?

Back

Population dispersion is the way in which individuals of a population are spread out in their environment.

Front

What type of population growth is characterized by a rapid increase followed by a leveling off?

Back

This is known as logistic growth.

Front

What is a density-independent limiting factor?

Back

A density-independent limiting factor is a factor that affects population size regardless of the population's density, such as natural disasters.

Front

What is exponential growth in population ecology?

Back

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

Front

Define carrying capacity in the context of population ecology.

Back

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

Front

What is the difference between emigration and immigration?

Back

Emigration is the movement of individuals out of a population, while immigration is the movement of individuals into a population.

Front

What role do predators play in population dynamics?

Back

Predators help control the population size of prey species, influencing the overall balance of the ecosystem.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.
