How Organisms Transform Food Into Energy In Ecosystems

The video covers lessons 1.6 and 1.7 of a science unit on ecosystems. Lesson 1.6 focuses on understanding how animals grow by converting food molecules into body molecules, using scientific arguments to support claims. Students apply these concepts to rainforest animals like jaguars and sloths. Lesson 1.7 introduces food webs, emphasizing the role of plants in ecosystems and how food molecules can be traced back to them. The video also includes vocabulary related to ecosystems and encourages students to think critically about the roles of different organisms and non-living components in ecosystems.

What is the main purpose of lesson 1.6?

• To learn about the flow of matter through ecosystems

• To explore the concept of food webs

• To understand the role of plants in ecosystems

• To study the behavior of rainforest animals

How do animals grow according to the lesson?

• By absorbing sunlight

• By changing food molecules into body molecules

• By consuming water

• By breathing air

What is a scientific argument?

• A debate between scientists

• A claim supported by evidence

• A theory about ecosystems

• A hypothesis without evidence

What is the focus of the activity on rainforest animals?

• To understand how jaguars and sloths grow and thrive

• To study the climate of rainforests

• To explore the diversity of rainforest plants

• To learn about the history of rainforests

What does the term 'ecosystem' refer to?

• A group of non-living things

• A single organism

• A type of plant

• A community of organisms and their environment

What is the purpose of lesson 1.7?

• To learn about the history of ecosystems

• To understand the cycling of matter and trace food molecules back to plants

• To explore the role of water in ecosystems

• To study the behavior of animals

What is a food web?

• A diagram showing what eats what in an ecosystem

• A list of animal species

• A chart of plant growth

• A diagram showing the flow of water in an ecosystem

What happens to the food web if there are no frogs or carp?

• It becomes more complex

• It becomes simpler

• It remains unchanged

• It may collapse or change significantly

Where do food molecules in the ecosystem originate?

• From the air

• From water

• From the soil

• From plants

What is the significance of plants in a food web?

• They are the origin of food molecules

• They provide shelter for animals

• They regulate the temperature

• They are the primary source of water
