Ecosystem Factors and Relationships

The video explores a pond ecosystem, highlighting the importance of understanding both biotic and abiotic factors. Biotic factors include all living organisms, such as plants and animals, while abiotic factors encompass non-living elements like water, sun, and soil. The video emphasizes the interdependence of these factors, illustrating how changes in abiotic factors can significantly impact biotic components. For instance, the removal of water would lead to the disappearance of fish and other aquatic life.

What is the primary focus when trying to understand an ecosystem?

• The color of the water

• Non-living components

• Only animals

• Only plants

• Living organisms

Which of the following is NOT an abiotic factor in a pond ecosystem?

• Dissolved oxygen

• Sunlight

• Fish

• Soil

How are abiotic and biotic factors related in an ecosystem?

• Abiotic factors are more important

• They are independent of each other

• They have no relation

• Biotic factors depend on abiotic factors

What might happen if water is removed from a pond ecosystem?

• More fish will appear

• Plants will thrive
