1. Question
1 pointsWhy are night blooming flowers are mostly white in colour?
CorrectNight blooming flowers use their light reflecting properties and fragrance to attract
insects for pollination. They are therefore white, or light in color, in order to reflect the
moonlight and advertise their beauty to passing moths and other insects.IncorrectNight blooming flowers use their light reflecting properties and fragrance to attract

2. Question
1 pointsWhich of the below mentioned animals undergo Aestivation
1. Earthworms
2. Bats
3. Crocodiles
4. Frogs and Toads
Select the correct answer using the following Code:CorrectAbout Aestivation: Aestivation is a period of deep and prolonged sleep, or torpor, that
occurs in the summer or dry season in response to heat and drought. Food can often be
scarce at such times, so animals avoid using up hard won energy reserves by lowering
their metabolic rate. This reduces the need for food and water during hard times,
ensuring longer-term survival.IncorrectAbout Aestivation: Aestivation is a period of deep and prolonged sleep, or torpor, that

3. Question
1 pointsIn order to survive in Cold winter, Tundra vegetation adopt certain features to
survive, consider the following statements in this regard
1. Plants are dark in color to absorb solar heat
2. No leaves or small leaves
3. Grow in clumps to protect one another from the wind and Cold
4. Covered with hair which helps keep them warm
Which of the above mentioned is/are Correct?CorrectIncorrect - Question 4 of 5
4. Question
1 pointsWhich of the animals mentioned below are examples of ectotherms
1. Goldfish
2. Lizard
3. Frog
Select the correct answer using the following Code:CorrectEndotherm: Body regulates its own temperature because cellular functions and processes
work the best when they are approximately 98.6 ° F. Because body is able to maintain a
specific temperature despite the surrounding conditions. There are many organisms that
are not able to maintain their own body temperature, and these are called ectotherms.
Ectotherms depend on the external environment to either warm or cool themselves
because their body does not do this for them.
Reptiles are a great example of this. Snakes, turtles, lizards, and alligators are all examples
of animals that use the sun to warm themselves.IncorrectEndotherm: Body regulates its own temperature because cellular functions and processes

5. Question
1 pointsConsider the following statements:
1. Gross primary productivity of an ecosystem is the rate of production of organic
matter during photosynthesis.
2. Net primary productivity minus respiration losses (R), is the Secondary productivity
Which of the above mentioned statements is/are NOT correct?CorrectThe Primary productivity can be divided into: Gross Primary Productivity (GPP) of an
ecosystem is the rate of production of organic matter during photosynthesis. A
considerable amount of GPP is utilized by plants in respiration. Net Primary Productivity
is gross primary productivity minus respiratory lossesIncorrectThe Primary productivity can be divided into: Gross Primary Productivity (GPP) of an
