Multiple choice biology habitat and adaptation terrestrial adaptations in plants desert ecosystem adaptation in terrestrial plants

Which of the following is an important adaptation of animals too the cold climate?

  1. Thin layer of body fat

  2. Aestivation

  3. Increased tendency to shivering

  4. Reduced surface area to volume ratio
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Temperature affects the the absolute size of an animal and the relative proportions of various body parts, Birds and mammals attain grater body size in cold regions than in warm areas. But poikilotherms are smaller in cold region. This is Bargeman's rue. This is true because small animals have larger surface area relative to their volume, so if they are in cold, they lose their body heat very fast. In cold climate, reduced surface area to volume ratio is ideal. So, the correct answer is 'Reduced surface area to volume ratio'.

Which of the following is not an important adaptation of animals to cold climate?

  1. Thin layer of body fat

  2. Aestivation

  3. Increased tendency to shiver

  4. Reduced surface area to volume ratio
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The animals living in cold climate have various physiological adaptations like:

1) A thick layer of body fat called as Blubber to avoid loss of heat from body tissue.

2) Hibernation is a property of suspended metabolism in these organisms to surpass cold conditions.similar mechanism called aestivation exists in desert animals to survive in arid and hot conditions.

3) Increased tendency to shiver causes an increase in body temperature because of exercise thus help to withstand low temperatures.

4) The reduced surface area to volume ratio to prevent heat loss from the body surface. So, the correct answer is 'Aestivation'.

Animals living in cold regions have?

  1. legs to run fast

  2. fat for additional insulation

  3. long necks

  4. long eye lashes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Animals that live in colder areas have to protect their bodies against extremely cold environmental conditions. Their bodies cannot withstand such cold climates. So, they have a thick white fur over their bodies. This provides an additional layer over their skin. As a result, the air gets trapped in this layer and it cannot pass through it, keeping their bodies insulated against the excessive cold.

So, option B " fat for additional insulation" is the correct answer.

Multiple choice evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

Which one is not a component of environment?

  1. Sunlight

  2. Decomposers

  3. Water

  4. Air
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Environment is defined as a natural ecosystem that includes everything around the biotic factors. These are nonbiotic factors. These includes air, water, sunlight. Decomposers are the biotic factors of an ecosystem.

Thus, the correct answer is 'Decomposers.'

Multiple choice evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

Two species in the same habitat can coexist when they

  1. differ in their use of resources

  2. share the same resource in different ways

  3. use the same resource at different times

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

2 species that are coexisting in a particular area have few characteristic features to avoid intraspecific competition.

These differ in the use of resources
These share the same resource in different ways
These use the same resource at different times
So, the correct option is 'all of these'

Multiple choice evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

An example of biotic components in nature is

  1. Cells

  2. Organic molecules

  3. Plants

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Biotic components are the living things that shape an ecosystem. Examples of biotic components include animals, plants, fungi, and bacteria. Abiotic components are non-living components that influence an ecosystem. Examples of abiotic factors are temperature, air currents, and minerals.

So, the correct answer is 'D'.
