Ecosystem Components and Interactions

The video explores the complexity of ecosystems, focusing on the interaction between abiotic and biotic components. It discusses how abiotic factors like sunlight and temperature influence ecosystems and how biotic components, such as trophic levels, interact. The video also highlights the direct and indirect interactions within ecosystems and the role of these interactions in evolution.

What are the two main components of ecosystems?

• Land and Water

• Flora and Fauna

• Air and Soil

• Biotic and Abiotic

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

• Precipitation

• Temperate Forest

What is the primary diet of herbivores?

• Plants

• Insects

• Fruits

• Meat

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

• Omnivores

• Carnivores

• Herbivores

• Decomposers

What type of interaction occurs when one organism consumes another?

• Competitive Interaction

• Symbiotic Interaction

• Direct Interaction

• Indirect Interaction

How do hawks indirectly aid the growth of berries?

• By pollinating the flowers

• By eating the mice that consume the berries

• By spreading the seeds

• By providing shade

Which trophic level tends to have the most direct interactions with others?

• Carnivores

• Omnivores

• Herbivores
