A) Tropical B) Temperate C) Polar D) All of these

Explanation / Answer

3) the product of photosynthesis is Oxygen

CO2 (carbon dioxide) + H2O (water) + photon (energ)y ? [CH2O] carbohydrate + O2(oxygen)

4) Primary consumers are herbivore, they feed on primary consumers and initiate the food chain.

5)The energy in an ecosystem is transferred from one tropic level to another through food chain.The efficiency of this transfer of energy is known is transfer efficiency.

6)If the transfer efficiency is 8% the feeding 500kg corn would produce 40 kg of beef.

7) sea otters are a keystone in the ecosystem of west coast kelp ecosystem.the feed on sea urchins and maintain a healthy ecosystem.

8) Zooxanthellae are one of the most important primary producers.

9) coral reefs are located in tropical oceans near the equator as coral reefs are sensitive to both temperature and salinity and ideal condition for their growth and survival is provided by tropical oceans
