Front

What is the equation for exponential population growth?

Back

dN/dT = rN

Front

What type of biome is characterized by organisms adapting to both air and water exposure due to tidal changes?

Back

Intertidal Zone

Front

What does community ecology study?

Back

The interactions between populations of different species in the same area

Front

What concept is demonstrated when two species of barnacles occupy different parts of the same tidal zone?

Back

Competitive exclusion

Front

What is a likely outcome of competitive exclusion?

Back

One species will be driven to extinction or forced to move to a different habitat.

Front

Define resource partitioning.

Back

The process by which species use different resources or occupy different niches to reduce competition.

Front

What is the principle of competitive exclusion?

Back

Two species competing for the same resources cannot coexist if other ecological factors are constant.

Front

What is niche differentiation?

Back

The process by which competing species use the environment differently to coexist.

Front

What is the significance of genetic diversity in community ecology?

Back

It enhances the resilience of populations and ecosystems to environmental changes.

Front

What is symbiosis?

Back

A close and often long-term interaction between two different biological species.
