25. How do coral reefs contribute to the survival of fishes? fishes fly in coral reefs fishes play in coral reefs fishes swim in coral reefs fishes get food and shelter from coral reefs

26. How do organisms use the areas under the mangrove trees? as fuel as foods as forest as breeding grounds

27. What should you NOT do to prevent pollution on nearby bodies of water such as estuaries and intertidal zones? Creating septic tanks on comfort rooms. Utilizing recyclable materials to form new products Planting native vegetation along the coastline and estuaries Using toxic pesticides and fertilizers especially near bodies of water

28. Why do we need to protect and conserve estuaries and intertidal zones? Because they store harmful chemicals Because they are found near our barangays Because they make the Earth more beautiful Because they serve as home to various aquatic life

29. How does cleaning the coastal areas affect the ecosystem? It gives jobs to people. It destroys the environment. It contributes a small number of fishes. It provides sustainable shelter to organisms.

30. How can people protect the ecosystem? Sell the corals. Plant more trees. Cut the trees in the forests. Kill the endangered species.

31. What should you do when you go boat riding with your friends so that you won’t disturb or damage the marine life? I will dump your trash overboard. I will sail on the sensitive areas like seagrass beds. I will not install marine sanitation devices on your boat. I will regularly check the boat’s engine to reduce oil leaks.

32. What will you do if you see products made from endangered marine animals being sold in the market? I will patronize their products. I will report them to the authorities. I will help them to sell their products. I will encourage them to make more of these products.

33. What do you call the consumer that feeds on plants or producers? carnivores consumer herbivores producer

36. What happens to the plants and animals when one type of animal leaves or dies out? Nothing will change. They will continue to live. Another plants and animals will produce and born. They may die or leave the area in search of other food and shelter sources.

37. What will animals likely do when its ecosystem was destroyed? stay there get revenge live on water find a new place to live

38. Which of the following gives an example of how birds modify their environment to meet their needs? Birds find food. Birds use twigs to build a nest. Birds breathe air and drink water. Birds hatch eggs and feed their young.

39. What is a relationship between two species where one species benefits, and the host is harmed? commensalism competition parasitism predation

40. What do you call the relationship between two organisms in which one organism benefits and the other is unaffected? commensalism competition parasitism predation

41. If animals cannot adapt to changes in their environment, what is likely to happen? Extinction Hibernation Locomotion Metamorphosis

42. Which of the following facts describes how one animal depends on another to survive? A bee fertilizes plants as it collects pollen. A penguin uses its webbed feet for swimming fast A tick attaches itself to a deer and feeds on its blood. A cow causes insects to jump around as it eats grass from the ground.

43. Which answer shows an organism obtaining energy without depending on another organism? A deer eats grasses, flowers, and vegetables. A snake preys on rodents and small reptiles. A pecan tree produces food through photosynthesis. A mushroom absorbs nutrients from decomposing plants.

44. Which of these living organisms is interacting with another living organism in the environment? A pelican skims the ocean surface. A mole digs a tunnel in a forest meadow. A hummingbird drinks nectar from a flower. A white hare burrows in the snow for camouflage.

47. Some mushrooms breakdown the remains of dead trees. Some beetles breakdowns the remains of dead animals. How do these processes benefit most plants? They release oxygen into the air. They make space for new animals. They return nutrients into the soil. They decrease the population of herbivores.

48. Which of the following is an example of interdependence among living things? Plants rely on the sun for energy. Frogs bury themselves in mud for shelter. Children count on their parents for food and shelter. Wind carries seeds through the air so plants grow in another area.

49. A student observing animals in a park records ways they interact with living and nonliving parts of their environment.

A spider crawls under a rock for protection. A bird reacts to morning sunlight by singing.

50. Which of the following examples do not shows how one organism is dependent on another for survival. A plant absorbs sunlight to make its own food.

51. Which statement best explains why many kinds of plants and animals can live together in an ecosystem? They all care for and protect one another. They all feed on the same things, so they compete for food. They are all part of a food chain and depend on each other to live. They have nothing to do with each other, so they can live together.
