Penguins cannot live in the desert. which of the following is the most important limiting factor? temperature light soil quality population density

The correct answer is Temperature.

Explanation:

Arctic penguins live in thick ice sheets most of the time, due to the extremely cold climate. Others live on sandy beaches and small islands.

All penguins have something in common, they live near the sea where they can hunt and feed. These animals need to feed on a large number of fish, krill, squid, and crustaceans to survive. It is for this reason that they live mainly near cold-water streams, as it is from these streams that they can extract large amounts of food.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
