  1. Both statements 1 and 2 2 are correct.

  2. Statement 1 is correct but statement 2 is incorrect.

  3. Statement 1 is incorrect but statement 2 is correct.

  4. Both statement 1 and 2 are incorrect.

Show answer
Correct Option: B
Explanation:

Tropical rainforests are disappearing fastly from India due to deforestation, habitat loss and fragmentation. These forests are of extreme value since they contain the maximum biodiversity.  

Which of the following statements is correct? 

zoology environmental factors environmental factors and their measurements climate factors marine life

  1. The flora of a place is heavily defined by availability and quality if water.

  2. The availability of light on land is closely linked with that of temperature since Sun is the source for both.

  3. Topography does not affect biodiversity

  4. Soil composition also affects the seepage of water in to ground.

Show answer
Correct Option: C
Explanation:

Topography means the physical features of a place such as hills, plains, slopes, rocks, valleys,etc. The topography affects the distribution of organisms directly or indirectly by influencing other factors, such as light intensity, wind velocity nature of sol, rainfall water currents or wave action. 

The amount of energy the earth receives from the sun, per year is

  1. 1000 k calories

  2. 10\times10^{30} calaories

  3. 5\times10^{20} calaories

  4. 10\times10^{23} calaories

Show answer
Correct Option: A
Explanation:

The sun's surface emits about 63 million watts of energy per square meter. By the time it reaches the Earth, after traveling 150 million kilometers, or 93 million miles, it has dimnished to 1,370 watts per square meter which are equal to thousand of kilocalories.

so, the correct option is '1000 Kcalories'.

Which the following statement is incorrect?

zoology environmental factors environmental factors and their measurements climate factors marine life

  1. Osmoconformers are able to maintain osmotic concentration of their cells by either physiological or behavioral means

  2. Most vertebrates, except the birds and mammals are unable to theregulate

  3. Success of mammals is mainly due to their ability to thermoregulate and live comfortably whether they are in Antarctica or in Sahara desert.

  4. None of these

Show answer
Correct Option: A
Explanation:

Osmocoformers are the organisms that change the osmotic concentration of their body with the change in ambient conditions. Their body fluids are in osmotic balance with the environment For many marine invertebrates the osmolarity and ionic concentrations of their body fluids are similar to those of the sea water in which they live. 

Oxygen is contributed to the atmosphere by

  1. Green plants

  2. The weathering of rocks

  3. Fossil-fuel combustion

  4. All the above

Show answer
Correct Option: A
Explanation:

Photosynthesis is a process that converts $CO _2$ into organic compounds and starch (carbohydrate) using energy from sunlight. $O _2$ is also released during this process.

  1. availability of food

  2. growth of plants

  3. breedingofanimals

  4. the amount of oxygen dissolved in water

Show answer
Correct Option: C
Explanation:

Aquatic organisms are used to a certain range of temperature in the water-body where they live. A sudden marked change in this temperature can be dangerous for them. It affects breeding of aquatic animals. The eggs and larvae of various animals are particularly susceptible to temperature changes.
