  2. Name 2 living and 2 nonliving things in an ecosystem.

  3. Living 1. Plants2. AnimalsNon-Living1. Water2. Rocks

  4. Which type of organisms make their own food?

  5. Producers: PLANTS

  6. Name four different types of ecosystems.

  7. Pond, Ocean, Forest, River

  8. What is the primary energy source on the Earth?

  9. THE SUN!

  10. Explain how an ecosystem can be self-sustaining when there is no human interaction.

  11. As organisms grow they are held in check by other factors in the environment such as depletion of food, disaster, and an increased number of predators.

  12. Name 4 things that would make a food chain.

  13. Sun-Producer-Consumer-Decomposer

  14. Explain in you own words the difference between a food web and food chain.

  15. A food web is all food chains in a community. In a food chain, an animal may eat more than one organism.

  16. What will happen if all of the plants died in an ecosystem?

  17. Animals would have to relocate or die.

  18. Describe the food chain in your terrarium and aquarium.

  19. Producer (grass, green plants)Consumer (grasshopper)Consumer/Scavenger (pill bug)Decomposer (rotting leaf matter)

  20. Give examples of fresh water and salt water ecosystems including producers, consumers, and decomposers.

  21. Examples include:Fresh water: pond snail, fish, eloda plantSalt water: crab, sea snail, seaweed

  22. What does an herbivore eat to get energy?

  23. Plants

  24. Which organisms recycle decaying plants and animals into something useful?

  25. Decomposers

  26. Describe how the sun is the Earth’s main energy source.

  27. Energy comes from the sun’s rays to heat the Earth.

  28. Nature recycles decaying plants and animals. How is energy from the soil used in an ecosystem?

  29. It puts nutrients into the soil that nourish new plant growth.

  30. If the rabbits in a forest are overeaten by foxes, what effects would occur due to this scarcity?

  31. The hawks, for example will relocate or die without their main food source.

  32. Name 3 types of pollutants.

  33. Rock Salt, Acid Rain, Fertilizer

  34. How does acid rain impact our environment?

  35. Too much acid rain changes PH level of the soil and water which disturbs the balance of the ecosystem.

  36. Using a PH scale, Mr. Brancaccio was checking a liquid to find whether it was an acid, base, or neutral. What is indicated if the PH scale range is between 2 and 4?

  37. The lower the number, the more acidic the liquid is.

  38. How does an automobile pollute the environment?

  39. It burns fossil fuel (gas) and produces dangerous gases out of the tailpipe. It uses many gallons of oil in the engine and transmission for routine maintenance.

  40. What would happen if we fail to reduce the amount of pollutants into the environment? What can we do to be responsible citizens?

  41. The balance of Earth’s ecosystem will be destroyed. RECYCLE! Do More With Less…

  42. Name a saltwater ecosystem.

  43. Ocean

  44. Describe how you would test the PH of soil with (PH) litmus paper.

  45. Press PH paper into the soil until it gets wet.

  46. Where is the oxygen coming from in your aquarium?

  47. green plants

  48. What is the purpose of using models in science?

  49. We use models to simulate something larger and predict how they will work in the real world.

  50. Describe a situation when a change in an organism’s habitat could be beneficial.
