Students learn the many ecological factors that affect the carrying capacity for populations of wild species.

Describes conditions in a desert that limit how large populations of species can grow.

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...

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

This lesson will explain how a limiting factor effects the size of a population. It is 3 of 4 in the series titled "Limiting Factor."

This lesson will explain how a limiting factor effects the size of a population. It is 4 of 4 in the series titled "Limiting Factor."

This lesson will explain how a limiting factor effects the size of a polulation. It is 2 of 4 in the series titled "Limiting Factor."

Students build a model ecosystem to simulate the life and limiting factors of the Terrapin turtle.

[Free Registration/Login may be required to access all resource tools.] Covers different patterns of population growth.

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

Given scenarios, illustrations or descriptions, the student will describe how long-term survival of species is dependent on changing resource bases that are limited.

Some biologists study the population of organisms belonging to the same species. Discover the factors that limit populations and what affects the health of a population.

Information is given on the Eastern Wolf's appearance, migration, food, breeding and predators. Several of the topics are highlighted with video clips. Research questions and answers examine the environmental impact on the wolves in the...

In this ecosystem consisting of hawks, snakes, rabbits and grass, the population of each species can be studied as part of a food chain. Disease can be introduced for any species, and the number of animals can be increased or decreased...

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...

Explore how environmental conditions affect the adaptation of birds in this simulation. The amount of annual precipitation on an island is controlled by you while you track changes in the thickness of bird beaks over a five-year period....
