Ecosystem Functions and Nutrient Recycling

The video tutorial explores the life cycles of plants and animals, highlighting their growth, reproduction, and eventual death. It explains the differences between living and nonliving things and the importance of decomposers in nutrient cycling. Students engage in hands-on activities with pea plants and fruit flies to understand developmental stages. The Delta Science Reader provides additional insights into various life cycles and features notable biologists like Jane Goodall.

What is the difference between a nonliving thing and a dead thing?

• Dead things can reproduce, but nonliving things cannot.

• Nonliving things were never alive, while dead things were once alive.

• Nonliving things can grow, but dead things cannot.

• Nonliving things need air, but dead things do not.

Which of the following is NOT a requirement for plant survival?

• Food

• Water

• Air

• Light

What is the primary role of decomposers in the ecosystem?

• To pollinate flowers

• To provide shelter for animals

• To produce food for plants

• To break down dead organisms and recycle nutrients

Which of the following nutrients is NOT mentioned as being recycled by decomposers?

• Magnesium

• Iron

• Zinc

• Calcium

What is the significance of nutrient recycling in ecosystems?

• It enriches the soil for new plant growth.

• It helps in the growth of nonliving things.

• It prevents the growth of fungi.

• It reduces the need for sunlight.

In the hands-on activities, which two organisms do students maintain?

• Tomato plants and bees

• Researching marine life

• Long-term study of chimpanzees

• Investigating desert ecosystems

What do students compare in the final reading section?

• The colors of different flowers

• The sizes and weights of newborn animals

• The speed of various animals
