Ecosystem Components and Interactions

The video explores the complexity of ecosystems, focusing on the interaction between abiotic and biotic components. Abiotic components like sunlight and temperature influence the environment, while biotic components, including various trophic levels, interact through food chains. The video also highlights how these interactions can drive evolutionary changes.

What are the two main components of ecosystems?

• Biotic and Abiotic

• Flora and Fauna

• Land and Water

• Sunlight and Soil

Which of the following is NOT an abiotic component?

• Sunlight

• Precipitation

• Temperature

• Herbivores

In which type of forest is precipitation more varied?

• Temperate Forest

• Tropical Rainforest

• Boreal Forest

• Mangrove Forest

What is the primary diet of herbivores?

• Meat

• Plants

• Insects

• Fish

Which trophic level includes animals that eat both plants and other animals?

• Herbivores

• Carnivores

• Decomposers

• Omnivores

What type of interaction occurs when one organism consumes another?

• Symbiotic Interaction

• Direct Interaction

• Indirect Interaction

• Competitive Interaction

How do hawks indirectly help berries grow?

• By fertilizing the soil

• By providing shade

• By eating mice that consume the berries

• By pollinating them

Which trophic level has the most direct interactions with others?

• Decomposers

• Omnivores

• Carnivores

• Herbivores

What natural event can cause forest fires and alter habitats?

• Volcanic Eruptions

• Tsunamis

• Thunderstorms

• Earthquakes

What role do interactions between ecosystem components often play in evolution?

• They are catalysts for evolution

• They reverse evolution

• They have no effect

• They hinder evolution
