Factores abióticos en los ecosistemas

The video discusses how changes in abiotic factors, like soil and air quality, can impact ecosystems. It highlights the Colorado River's transformation due to water diversion, leading to the loss of wetlands and affecting local biodiversity. Pollution is also examined as a critical factor altering ecosystems and climate, threatening species diversity and ecosystem stability.

What is an example of an abiotic factor that can influence an ecosystem?

• Plant species diversity

• Predator-prey relationships

• Animal migration patterns

• Soil composition

How did the construction of dams in the 20th century affect the Colorado River?

• It improved the habitat for aquatic life.

• It caused the river to no longer reach the sea.

• It led to the creation of new wetland ecosystems.

• It increased the river's flow into the Gulf of California.

What percentage of wetlands have disappeared due to changes in the Colorado River?

• 50%

• 100%

• 70%

• 90%

How does pollution affect lichens?

• It makes them more colorful.

• It directly affects their growth.

• It has no effect on them.

• It helps them grow faster.

What is a consequence of reduced species diversity in an ecosystem?

• More stable climate conditions

• Enhanced biodiversity

• Increased resilience to changes

• Greater vulnerability to extinction
