Q.

Write the temperate zone country list.

Q. Which of the following biomes face the minimum and maximum mean annual temperature respectively?

1. Arctic tundra and tropical rain forest
2. Tropical rain forest and desert
3. Tropical rain forest and arctic tundra
4. Desert and coniferous forest

Q.

On what basis are the biomes identified?

Q. The tilt of the Earth’s axis is the most important reason for seasons to occur.

1. True
2. False

Q. Match the following
$\begin{array}{cc}ColumnI& ColumnII\\ P)Savanna& I)Heavyrainfall\\ Q)Desert& II)Norainfall\\ R)Rainforest& III)Twoseasons\\ S)Taiga& IV)Coldestforestbiome\end{array}$

1. P-III, Q-II, R-I, S-IV
2. P-II, Q-III, R-IV, S-I
3. P-IV, Q-I, R-II, S-III
4. P-I, Q-IV, R-III, S-II

Q. Why do we have seasons?

1. Due to the rotation of the earth
2. Due to the revolution of the earth around the sun
3. Due to a tilt in the earth's axis
4. Because earth's orbit is elliptical, and we have summer when the earth is closest to the sun and winter when it is farthest away.

Q. Which of the following statement is true about a biome?

1. It has the same type of ecosystem
2. Climate will vary from region to region in a biome
3. We cannot determine which biome an organism belongs to, by studying the characteristic features of the organism.
4. Biodiversity varies from one biome to another

Q. Read the following statements (I - III) and identify the correct statement(s‌).

I. Tropical forests show the maximum variation in temperature, when the mean annual temperature is plotted against mean annual precipitation in a graph.
II. Microbes can be found everywhere but human intestine does not provide a suitable habitat for them.‌ ‌
III. Temperature affects the kinetics of enzymes and through this it affects the metabolic activity and other physiological functions.
