The two sides of a given mountain have the same latitude and altitude Are they likely to have the same climate

  1. No, because there is likely to be less water on the side of the mountain that faces away from the prevailing winds

  2. No. because there is always on desert on one side of a mountain

  3. Yes, because latitude and altitude are the two most important climate-controlling factors

  4. Yes, because locations at the same latitude all have the same climate

A Correct answer
Explanation

Although latitude does play a major role in determining what kind of climate a certain place will have, there are many other factors that will play a part s well. Here are a couple of major factors that can make cities at similar latitudes have very different weather.

So, the correct option is 'No, because there is likely to be less water on the side of the mountain that faces away from the prevailing winds'.

The ultimate energy source of all ecosystems is?

  1. Producers

  2. Organic molecules

  3. Carbohydrate

  4. Solar radiation

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. The overall productivity of an ecosystem is controlled by the total energy available.

So the correct option is 'solar radiation'.

Out of the total proposed cost of various ecosystem services, cost of climate regulations and habitat for wildlife are.

  1. $50\%$
  2. $10\%$
  3. $6\%$
  4. $25\%$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Robert Constanza and his colleagues have put the value of ecosystem services to $33$ trillion dollars a year. Out of which $50\%$ is proposed for formation of soil, prevention of flood and mitigating droughts. The value of $10\%$ each for nutrient cycle and recreation and $6\%$ for climate regulation and habitat preservation for wild flora and fauna has been proposed.

Edaphic factor refers to.

  1. Water

  2. Soil

  3. Relative humidity

  4. Altitude

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Edaphic factors are classified under the abiotic factors affecting an ecosystem. Edaphic factors include factors of soil, e.g., soil texture, substratum, topography, mineral composition, pH, etc. These factors can influence the distribution and interrelationships of organisms, as well as rate of decomposition.

Multiple choice biology the habitat of living climate factors abiotic components organisms and environment

Life arose in

  1. Soil

  2. Fresh water

  3. Marine water

  4. Air

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

We know that the environment we live in is made up of 2 components, namely living (biotic) and non-living (abiotic). Different theories were proposed to study the origin of the wife. But they lead to the conclusion that life had originated on earth in seawater and marine organisms were one of the first to emerge. In earth's early atmosphere, there was no ozone layer, thus the UV rays of the sun could directly reach the earth. As living organisms cannot survive UV radiation directly, many scientists believed that life originated in aquatic habitats. Apart from this, different requirements of these early organisms were also fulfilled in the deep-sea vents. 

Thus, option C 'Marine Water' is the correct option.

Terrestrial life would become impossible with

  1. Disappearance of moon

  2. Decrease in mean annual temperature by $10^o C$
  3. Change in orbit of earth

  4. Change in atmosphere permitting all solar radiations to reach lithosphere

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The total amount of solar radiation reaching to the lithosphere do not enter the surface of the earth as it would heat up the earth making it unsuitable for any life. Therefore, 35% of the solar radiation are reflected back to the space.

So, the correct answer is option D.

Multiple choice biology living in harmony climate factors abiotic components organisms and environment

The abiotic factors of the environment are
I. Temperature
II. Humidity
III. Vegetation

  1. I only

  2. II only

  3. III only

  4. I and II only

  5. I, II and III

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An ecosystem is made up of abiotic components or abiotic factors which are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors include water, light, radiation, temperature, humidity, atmosphere and soil. 

Biotic components are the living things that shape an ecosystem. Biotic components usually include Producers (vegetation), Consumers and Decomposers. Therefore only temperature and humidity are included under Abiotic factors. Hence, the correct answer is option D.

All of these are examples of abiotic factors except 

  1. Mushrooms

  2. Soil type

  3. Average yearly rainfall

  4. Sunlight

  5. Relative humidity

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The environment is a complex of many factors which surround an organism. These factors are known as environmental factors or ecological factors which may be either living or biotic and non-living or biotic. 
Biotic factors include plants, animals, microbes etc.
Abiotic factors are the non-living factors, substances, and conditions of the environment which influence the physiology, survival, function, and reproduction of organisms. These factors are divided as:
1. Direct factors- For example, light, temperature, humidity of the air, soil air, soil water, soil nutrients etc.
2. Indirect factors- For example, soil structure, soil organisms, altitude, wind, slopes etc.
Hence, Mushrooms will be included under biotic factors and soil type, average yearly rainfall, sunlight and relative humidity will be included under abiotic factors.
So, the correct answer is 'Mushrooms'.
