TAA Ecosystem Concepts and Relationships

The video explores the TAA ecosystem located in the midwestern Canadian Shield forests, focusing on abiotic and biotic factors, predator-prey and symbiotic relationships, density factors, competition, and the food pyramid and web. It also discusses the biogeochemical cycles and the impact of human activities like deforestation on the ecosystem.

Which of the following is an abiotic factor in the TAA ecosystem?

• White birch trees

• Canadian lynx

• Snowshoe hare

• Heavy snowfall

What is a primary producer in the TAA ecosystem?

• Moose

• Jack pine trees

• American beaver

• Bald eagle

Which of the following is an example of a predator-prey relationship in the TAA ecosystem?

• Beaver and otter

• Canadian lynx and Snowshoe hare

• Moose and white birch trees

• Muskrat and carp

What is a density-independent factor affecting the TAA ecosystem?

• Symbiotic relationships

• Predation by bald eagles

• Temperature variations

• Competition for food

Which species compete for fish in the TAA ecosystem?

• Moose and Snowshoe hare

• American beaver and North American river otter

• Canadian lynx and bald eagle

• Muskrat and vole

In the TAA ecosystem's food pyramid, what role do herbivores play?

• Tertiary consumers

• Primary consumers

• Secondary consumers

• Primary producers

Which of the following is a tertiary consumer in the TAA ecosystem?

• Canadian lynx

• White birch trees

• Snowshoe hare

• American beaver

What is the primary process involved in the biogeochemical cycle in the TAA ecosystem?

• Symbiosis

• Evaporation and condensation

• Photosynthesis

• Decomposition

How does industrial logging impact the TAA ecosystem?

• Destroys primary producers

• Enhances food resources

• Promotes animal population growth

• Increases biodiversity

What would be the immediate effect of a flood in the TAA ecosystem?

• Rise in animal populations

• Cease of life due to lack of resources

• Increase in plant growth

• Improved water quality
