Students learn about Abiotic and Biotic Factors and how they affect the ecosystem in which an animal might live in.

This fun quiz has you choose between different images to decide whether it is biotic or abiotic. It also gives examples through illustrations of abiotic and biotic things.

A video and a short multiple-choice quiz on the topic of ecosystems, covering biotic and abiotic factors, and the roles organisms play in an ecosystem.

This lesson will introduce abiotic and biotic factors, giving examples and comparing/contrasting the two. It is 2 of 4 in the series titled "Abiotic and Biotic Factors."

[Free Registration/Login may be required to access all resource tools.] In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an...

Take this 8 question check quiz on abiotic factors. The quiz is multiple choice.

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.

In this activity, students' use a pH sensor and Temperature Sensor to measure and compare the pH and temperature of three aquariums over a period of several weeks. They will compare and understand how plants and animals affect the water...

Students define the characteristics of living and non-living things, identify living and non-living components of an ecosystem, and identify the roles of organisms in living systems.

Students review the study of living things and make connections back to Earth's systems. This unit focuses on how various species, grouped in populations and communities, work with the nonliving things around them to ensure survival.

A webpage giving an overview of ecology. Learn about the biotic and abiotic factors that make up an ecosystem as well as the different levels of ecology.

The abundance and distribution of organisms in an ecosystem is determined by biotic and abiotic factors. Animals and plants have adaptations to allow them to compete for resources.
