Question

True False

66. The science of ecology is merely an observational science used only to expand our knowledge of living organisms and has no practical application to human welfare

. 67. Because fresh water is constantly evaporating from salt water, it is considered a renewable resource

. 68. Distribution of individuals of a population is only affected by abiotic factors of the environment such as temperature and substrate composition.

69. A likely inhabitant of an area undergoing primary succession would be a lichen.

70. A major function of plant stems is to absorb water as rain runs along their length to the soil.

71. Temperate deciduous forests are characterized by trees that bear a year-long canopy of leaves and well defined wet and dry seasons.

72. Phosphorus can move over a large geographic area because the phosphorus cycle has a gaseous stage.

73. Coral reefs are typically located in shallow tropical waters and are very biologically diverse.

74. Angiosperms are plants that produce their gametes in specialized organs that make up what are referred to as flowers.

75. Photosynthesis and cellular respiration are two main metabolic processes that influence the carbon cycle.

76. Four biotic factors that are major components of climate are temperature, water, sunlight exposure and wind.

77. Nutrient cycling is strongly influenced by decomposition and vegetation present in ecosystem.

78. Because the atmosphere is so abundant in nitrogen gas, it is an easily accessible exchange pool for living organisms.

79. Both nitrogen and phosphorous are limiting factors in both terrestrial and aquatic ecosystems.

Answer 1

66) False

Ecology is the study of how organisms interact with one another and with their physical environment. The whole human welfare depends on the natural environment or the system. Making the connection between these two as a way to better motivate society to make better decisions and through this it enhances human life by creating a clean and better living environment.

67)True

Here the sentence is true by considering the water cycle.

68) False

Distribution of individual of a population is affected by abiotic factors as well as biotic factors at the same time.

69)True

Lichen, algae, and fungi are primary succession pioneer species.
