Explore biotic and abiotic factors that can influence the growth of populations of organisms in this interactive tutorial.

Discover how ecosystems respond to population growth limits.

This instructional activity begins with a PowerPoint slideshow that covers important ecological concepts about biomes, limiting factors, carrying capacity, and population growth. Students will look at the population dynamics involved...

Learn to distinguish between exponential and logistic growth of populations, identify carrying capacity, differentiate density-dependent and density-independent limiting factors, apply population models to data sets and determine...

Abiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment. Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting...
