• Question 1 of 5 1. Question Arrange the following levels of ecological organization from the smallest to the largest: a) Community < Ecosystem < Biome < Biosphere b) Community < Biosphere < Ecosystem < Biome c) Ecosystem < Community < Biosphere < Biome d) Community < Biosphere < Ecosystem < Biome Correct Solution: a) Ecosystem is the groups of organisms from all biological domains in conjunction with the physical (abiotic) environment. Biome is the continental scale (climatically and geographically contiguous areas with similar climatic conditions) grouping of ecosystems. Biosphere or Ecosphere is all life plus the physical (abiotic) environment. Incorrect Solution: a) Ecosystem is the groups of organisms from all biological domains in conjunction with the physical (abiotic) environment. Biome is the continental scale (climatically and geographically contiguous areas with similar climatic conditions) grouping of ecosystems. Biosphere or Ecosphere is all life plus the physical (abiotic) environment.

• Question 4 of 5 4. Question Consider the followings: Hard Underwater Surface Warm Oceanic Water Sediment-Free Water Nutrient Supply How many of the above are the environmental conditions required for the formation of coral reefs? a) Only two b) Only three c) All four d) None Correct Solution: c) Environmental conditions required for the formation of coral reefs: A hard-underwater surface like continental shelf or mid-oceanic ridges, is required for the compaction and solidification of coral polyps’ skeletons. Coral polyps thrive in warm water with temperatures around 20 degrees Coral reefs prefer relatively sediment-free water, as excessive sediment can impede respiration and cause early death of coral polyps. Adequate nutrient supply is essential for the healthy development of coral polyps.

• Question 5 of 5 5. Question Consider the following statements: Wildlife Sanctuaries provide protection to the entire ecosystem, that is, flora, fauna and landscape.

There are different categories of protected areas which are managed with different objectives for the larger motive of conservation. National Parks provide protection to the entire ecosystem, that is, flora, fauna, landscape, etc. of that region. The national parks not only conserve wildlife but also provide a diversion of environmental and landscape heritage in a manner that does not harm it, in order to provide enjoyment to future generations. National parks are given a greater degree of protection, with human activity greatly restricted. Only certain areas can be visited and only activities permitted by the chief wildlife warden of the state are allowed in the park. Wildlife Sanctuaries: Wildlife Sanctuary, as the name implies, is the place that is reserved exclusively for wildlife use, which includes animals, reptiles, insects, birds, etc. wild animals, especially those in danger of extinction and the rare ones, so that they can live in peace for a lifetime and keep their population viable.
