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

[Free Registration/Login may be required to access all resource tools.] For a population to be healthy, factors such as food, nutrients, water and space, must be available. Limiting factors are resources or other factors in 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."

Students control the environments in four different scenarios to discover how any changes might affect populations. The different simulations include microorganisms, rabbits, foxes, and other organisms.

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

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....
