Ecosystem Interactions and Components

The video explores the complexity of ecosystems, focusing on the interaction between abiotic and biotic components. Abiotic components like sunlight, precipitation, and temperature influence ecosystems, while biotic components are organized into trophic levels: herbivores, omnivores, and carnivores. The video discusses direct and indirect interactions within ecosystems and how these interactions can drive evolution.

What are the two main components of an ecosystem?

• Biotic and Abiotic

• Flora and Fauna

• Land and Water

• Sunlight and Soil

Which of the following is NOT an abiotic component of an ecosystem?

• Precipitation

• Soil Composition

• Sunlight

• Herbivores

In which type of forest is precipitation more varied?

• Tropical Rainforest

• Mangrove Forest

• Temperate Forest

• Boreal Forest

What is the primary diet of animals at the lowest trophic level?

• Plants

• Herbivores

• Omnivores

• Carnivores

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

• Carnivores

• Herbivores

• Decomposers

• Omnivores

How do hawks indirectly help berries grow?

• By pollinating them

• By eating mice that consume the berries

• By providing shade

• By fertilizing the soil

Which trophic level has the most direct interactions with other levels?

• Herbivores

• Omnivores

• Carnivores

• Decomposers

What natural event can alter the habitats of organisms in a forest?

• Drought

• Volcanic Eruption

• Thunderstorm

• Earthquake

What is a potential outcome of interactions between ecosystem components?

• Habitat destruction

• Decreased biodiversity

• Catalysts for evolution

• Increased pollution

Which of the following is an example of an abiotic-biotic interaction?

• A thunderstorm causing a forest fire

• A tree providing shade

• A fish swimming in a river

• A lion hunting a zebra
