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

This NY Regents prep site provides a nice overview of what abiotic and biotic factors of an ecosystem are, as well as a brief description of carrying capacity.

Students correlate graphs of vegetation vigor with those of temperature and precipitation data for four diverse ecosystems, ranging from those near the equator to the poles, to determine which climatic factor is limiting growth.

Discover how ecosystems respond to population growth limits.

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...

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

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

Learn how organisms rely on one another but also compete with one another within the same ecosystem.

This lesson introduces students to their task of designing a permanent guest village within the Saguaro National Park. The design must provide a true desert experience to visitors while also emphasizing sustainable design, protection of...

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...

Using the scientific method, control the environmental conditions for a fictional alien organism in order to learn how the organism responds to changes in conditions. Sunlight, water, and temperature can be varied to determine their...
