An ecosystem is composed of biotic factors of a community of living organisms interacting with one another which we can see in food chains/webs. These diverse organisms stay together because of the need of food. Population is referred to...

Abiotic components are the nonliving components of the biosphere. Chemical and geological factors, such as rocks and minerals, and physical factors, such as temperature and weather, are referred to as abiotic components.

Students define and provide examples of abiotic and biotic factors of different ecosystems. Then they investigate the importance of abiotic factors and physical processes within ocean ecosystems.

How do environmental factors affect the growth, development, and health of organisms? Students explore the effect of environmental factors on traits by investigating factors that affect the growth of plants.

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...

In this activity, students create a "web" to identify and demonstrate the interactions among the living and non-living parts of an environment. This information allows students to better understand what an environment is and to also...

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

Work samples, phenomena, assessment templates, and videos that directly address standard 3-LS3-2: environmental influence on traits.

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

This lesson plan introduces students to the concept of an environment and the interactions within it through written and hands-on webbing activities. The lesson plan also introduces students to environmental engineering careers and their...
