botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. A habitat 

  2. An ecosystem 

  3. An ecological footprint 

  4. The biosphere

  5. The carrying capacity

Show answer
Correct Option: C
Explanation:
A. A habitat is a place where an organism lives and represents a particular set of environmental conditions suitable for its successful growth.
B. An ecosystem is a whole biotic community in a given area including its abiotic environment.
C. An ecological footprint is the measurement of any productive area (land or water) that is used by the human beings to produce the resources consumed by them and absorb the waste generated.
D. The planet Earth along with its atmosphere that sustains life is called biosphere.
E. Carrying capacity is the maximum size of the population that an environment can sustain.
So, the correct answer is 'An ecological footprint'.

Which of the following describes the ecosystem services?

  1. Carbon fixation

  2. Pollination

  3. Perennial water

  4. All of the above

Show answer
Correct Option: D

A functional aspect of an ecosystem is

  1. Producers, consumers and abiotic environment

  2. Regulation of populations

  3. Light, temperature, oxygen and carbon dioxide

  4. Both A and C

Show answer
Correct Option: B
Explanation:

The functional aspects of an ecosystem include the regulation of populations, flow of energy, biogeochemical cycles, and the flow of nutrients. It also includes ecological succession, food chain, ecological pyramid, food web. Populations are regulated in an ecosystem through these food chains.

Thus, the correct answer is 'Regulation of populations.'

An ecosystem does not normally alter because it is in a state of

  1. Homeostasis

  2. Imbalance

  3. Deficient light

  4. Deficient components

Show answer
Correct Option: A
Explanation:

Ecosystem is made up of living and nonliving things. Living things include plants and animals. Nonliving things includes air, water, land.  It is composed of organisms interacting within communities. The importance of ecosystem lies in both cycling of minerals and flow of energy. It does not alter normally because it is in a state of homeostasis. There is always balance of organisms in an ecosystem within themselves and with changing environment.

Thus, the correct answer is 'Homeostasis.'

Ecosystem creates

  1. Food chains and food web

  2. Food web

  3. Habitats

  4. None of the above

Show answer
Correct Option: A
Explanation:

An ecosystem is made up of living and nonliving things. Living things include plants, animals. Nonliving things include air, water. It creates food chains and food web. A food chain is series of plants/animals which are interrelated in the form of organism being eaten as food by the other. plants are producers. The animals eating plants are called as primary consumers and animals eating primary consumers are called as secondary consumers. Decomposers are those which decomposes the waster organic matter. Food web is various interlinked food chains in a community.

Thus, the correct answer is 'Food chains and food web.'

Importance of ecosystem lies in

  1. Cycling opmaterials

  2. Flow of energy

  3. Both A and B

  4. None of the above

Show answer
Correct Option: C
Explanation:

Ecosystem is made up of living and nonliving things. Living things include plants and animals. Nonliving things includes air, water, land.  It is composed of organisms interacting within communities. The importance of ecosystem lies in both cycling of minerals and flow of energy. It contributes to the cycling of minerals and flow of energy.

Thus, the correct answer is 'Both A and B.'

According to Robert Constanza, 50% of the total cost of ecosystem services goes to

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Climate regulation

  2. Soil formation

  3. Recreation

  4. Nutrient cycling

Show answer
Correct Option: B
Explanation:

Robert Constanza gave price tags to ecosystem services. According to him, soil formation accounts for 50% of the ecosystem service. It is the most important ecosystem service. The other ecosystem services include purify water and air, mitigate droughts and floods, nutrient cycling, habitat for wild life.

Thus, the correct answer is 'Soil formation.'

Which one is included under ecosystem services?

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Protection of soil

  2. Conservation and purification of water

  3. Climate control

  4. All of the above

Show answer
Correct Option: D
Explanation:

The benefits which we obtain from the regulation of ecosystem processes such as climate regulation, natural hazard regulation, water purification, and waste management, pollination or pest control are known as Ecosystem services. Agroecosystems, forest ecosystems, grassland ecosystems, and aquatic ecosystems are included under these ecosystems. These are also known as regulating services. Examples include Climate regulation, Waste treatment, and disease regulation. 

So, the correct answer is 'All of the above'.

According to Robert Constanza, 50% of the total cost for ecosystem services goes to

botany ecological adaptations, succession and ecological services ecosystem services ecosystems ecosystem

  1. Recreation

  2. Soil formation

  3. Nutrient cycling

  4. Climate regulation

  5. Habitat for wildlife

Show answer
Correct Option: B
Explanation:
Robert Constanza and his colleagues have very recently tried to put price tags on nature’s life-support services. Researchers have put an average price tag of US $ 33 trillion a year on these fundamental ecosystems services, which are largely taken for granted because they are free. Out of the total cost of various ecosystem services, the soil formation accounts for about 50 per cent, and contributions of other services like recreation and nutrient cycling, are less than 10 per cent each. The cost of climate regulation and habitat for wildlife are about 6 per cent each.
So, the correct answer is 'Soil formation'.
