Ecosystem Interactions and Components

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

What are the two main components of ecosystems?

• Air and Soil

• Land and Water

• Flora and Fauna

• Biotic and Abiotic

Which of the following is an example of an abiotic component?

• Bacteria

• Precipitation

• Animals

• Trees

How does temperature variation affect ecosystems?

• It determines the size of animals

• It influences precipitation types

• It changes the color of plants

• It affects the soil composition

What is the primary diet of herbivores?

• Fish

• Meat

• Insects

• Plants

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

• Omnivores

• Carnivores

• Decomposers

• Herbivores

What is a direct interaction between trophic levels?

• Water evaporating from a lake

• Plants growing in sunlight

• One organism consuming another

• Animals sharing the same habitat

How do hawks indirectly aid berry growth?

• By providing shade

• By eating mice that consume berries

• By pollinating flowers

• By spreading seeds

Which trophic level has the most direct interactions with others?

• Decomposers

• Carnivores

• Omnivores

• Herbivores

What can thunderstorms cause in a forest ecosystem?

• Soil erosion

• Animal migration

• Forest fires

• Increased plant growth

What role do interactions between ecosystem components often play?

• They prevent species extinction

• They increase biodiversity

• They are catalysts for evolution

• They slow down evolution
