3. Ecosystems - $100 What makes up an ecosystem? What are the four ecosystems we learned about? Living things and their nonliving environment Ecosystems: pond, desert, rain forest, and coral reef

4. Ecosystems - $200 Give two examples of biotic and abiotic factors. 1. Biotic: Plants, animals, and microorganisms. 2. Abiotic: Rainfall and temperature.

5. DAILY DOUBLE

6. Ecosystems - $300 How do desert animals survive very hot and cold weather? How do they get their water? They live underground They get their water from the food they eat.

7. Ecosystems - $400 Name one abiotic factors in a pond ecosystem. Name one abiotic in coral reef environment. Pond ecosystem: water, soil Coral Reef ecosystem: Coral

8. Ecosystems - $500 Name and describe the four layers of the rain forest. Emergent layer – the tops of the tallest trees Canopy layer – has snakes and treefrogs Understory layer - below the canopy layer Forest floor - very few plants grow here because there is little light.

9. Dependence on Each Other - $100 How are plants used as shelter? Birds use plants to build their nests that they use as homes. Plants (e.g., trees) give animal a place to hide and stay safe from harm.

10. Dependence on Each Other - $200 How do animals help the process of pollination? Animals travel from flower to flower and the pollen sticks to them. When they go to a new flower they rub the pollen on it and it helps it reproduce.

11. Dependence on Each Other - $300 How do plants depend on animals to carry seed? Animals eat fruit and leave fruit seeds on the ground in their waste. Some seeds stick to animals’ fur and fall to the ground and grow into new plants.

12. Dependence on Each Other - $400 How do animals depend on plants? • Plants produce oxygen. • Plants are eaten by producers who would not survive without them. • Plants that are no longer living are eaten by decomposers. • Plants are the main source of energy entering food chains.

13. DAILY DOUBLE

14. Dependence on Each Other - $500 What is the process called when male cells (stamen) are transported to female cells (pistil) in a flower?The ovary at the base of the pistil turns into what after pollination? Pollination Fruit

15. Changes in Ecosystems - $100 Changes in the ecosystems can make it difficult for plants and animals to ________. Survive

16. Changes in Ecosystems - $200 How can a fire help an ecosystem? A fire can help a forest ecosystem from becoming too crowded.

17. Changes in Ecosystems - $300 An individual organism’s response to change is called _____________. Accommodation

18. Changes in Ecosystems - $400 What happens when ecosystems change? Animals change their behavior and habits to survive changes in the ecosystem.

19. Changes in Ecosystems - $500 • What does endangered mean? • What does extinct mean? • Endangered means there are only a few of a specific plant or animal alive in an ecosystem. • Extinct means that the specific animal or plant has all been destroyed or died.

20. Adaptations - $100 What do adaptations help an animal do? Adaptations help animals move, catch food, and live in certain climates.

21. Adaptations - $200 What are some adaptations of ocean animals? • Some animals have blubber to keep their body warm in the cold ocean water. • Some animals confuse its predators by looking like something else.

22. Adaptations - $300 What are some adaptations of desert plants and animals? • Plants have adapted so they need little water. • Some animals live underground to keep cool and safe. • Some animals sleep during the day and are active at night (nocturnal) when it is cool.

23. DAILY DOUBLE

24. Adaptations - $400 What are adaptations and give two examples of them? Adaptations are special features that help living things survive in their environment. A fish’s gills , a dragonfly’s wings, and an eagle’s sharp eyesight are adaptations.

25. Adaptations - $500 How do animals adapt? Some animals use camouflage to blend into their environment. Other animals use mimicry to hide by looking like other organisms.

26. Potpourri - $100 • It is a sweet drink found inside a flower. • It is the study of how organisms pass traits from one generation to the next. Nectar Genetics

27. Potpourri - $200 • Living things are _________. • Nonliving things are _____________. • Biotic • Abiotic

28. DAILY DOUBLE

29. Potpourri - $300 The rain forest ecosystem has __________ than any place on Earth. More Life

30. Potpourri - $400 What are some adaptations of arctic plants and animals? Animals have special adaptations to help them survive the cold. Polar bears have inner fur to keep it warm and outer fur to keep it dry. Some animals have large bodies so they don’t lose as much body heat.

31. Potpourri - $500 What does pollution do? Make living things sick and can even raise the temperatures on Earth.

32. FINAL JEOPARDY Science ?

33. What causes ecosystems to change? How can people protect ecosystems? • Natural events such as changes in weather and climate (e.g., hurricanes, tropical storms, drought) can cause ecosystems to change. Human activities such as air pollution, cutting down forests and digging for resources in Earth’s surface can cause ecosystems to change. • Laws are made to limit pollution and make hunting certain animals or picking certain plants illegal.
