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 numbers, often represented by a J-shaped curve.

Front

What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What is carrying capacity (K)?

Back

Carrying capacity (K) is the maximum number of individuals of a species that an environment can sustainably support over a long period.

Front

How does increased food availability affect carrying capacity?

Back

An increase in available food can raise the carrying capacity of an ecosystem, allowing more individuals to survive and reproduce.

Front

What is the first step in the eutrophication process?

Back

The first step is the occurrence of algal blooms, which block light from reaching lower levels of the water.

Front

What happens to aquatic plants during eutrophication?

Back

Aquatic plants cannot photosynthesize due to lack of light from algal blooms, leading to their death.

Front

What is a density-independent limiting factor?

Back

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

Front

What is the significance of sustainability in urban planning?

Back

Sustainability in urban planning ensures that resources are used efficiently and responsibly, allowing cities to thrive long-term without depleting resources.

Front

What is the role of bacteria in the eutrophication process?

Back

Bacteria decompose dead algae, consuming a large amount of oxygen in the process, which can lead to hypoxia and death of aquatic organisms.

Front

What is the impact of predators on carrying capacity?

Back

An increase in predators can decrease the carrying capacity of an ecosystem by reducing the population of prey species.
