Questions Related to environmental conservation and biodiversity

Which of the following statements is incorrect regarding biodiversity?

evs animal- the base of our life diversity in the living world environmental conservation and biodiversity biodiversity on earth and in india

  1. Biodiversity deals with biological and geographical units such as genes, chromosomes, species, families and biogeographic religions.

  2. Biodiversity is an addition sum of genetic, taxonomic and ecosystem diversity.

  3. It is a measure of the amount of resources shared by the human population.

  4. None of these

Show answer
Correct Option: C
Explanation:
  • Biodiversity refers to the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level.
  • It deals with biological and geographical units such as genes, chromosomes, species, families and biogeographic religions
  • It is an additional sum of genetic, taxonomic and ecosystem diversity.
  • Biodiversity is a measure of species richness i.e  The number of groups of genetically or functionally related individuals.
  • Hence Biodiversity is a measure of the number of resources shared by the human population is a wrong statement.
  • So, the correct answer is 'Option C'.

The term biodiversity is popularised by

  1. Odum

  2. Paul Ehrlich

  3. Edward Wilson

  4. Tilman.

Show answer
Correct Option: C
Explanation:

Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organisation.  

Among the ecosystem mentioned below where can one maximum biodiversity? 

evs animal- the base of our life diversity in the living world environmental conservation and biodiversity biodiversity on earth and in india

  1. Mangroves

  2. Desert

  3. Coral reefs

  4. Alpine Meadows

Show answer
Correct Option: C
Explanation:
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Biodiversity is important because it clears out our water, changes out climate, and provides us with food. Ecological diversity includes the variation in both terrestrial and aquatic ecosystems. Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of trophic levels and other ecological processes. A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Often called "rainforests of the sea", shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians.
So the correct option is 'coral reefs'.

Rate of replacement of species along a gradient of habitats/communities is called 

zoology diversity of life diversity in the living world environmental conservation and biodiversity biodiversity on earth and in india

  1. $\alpha$ - diversity

  2. $\beta$ - diversity

  3. $\gamma$ - diversity

  4. $\omega$ - diversity

Show answer
Correct Option: B
Explanation:

The local species pool is known as alpha diversity. It is also the diversity present within the community. Beta diversity is the diversity present between the communities. The diversity present in the ranges of communities is known as Gamma diversity.

So, the correct answer is 'β - diversity'.

The term biodiversity is related to

  1. All living plants

  2. All living animals

  3. All living plants and animals

  4. Living plants, animals and microbes found in their natural habitats

Show answer
Correct Option: D
Explanation:
Biodiversity is the term popularised by the sociobiologist Edward Wilson to describe the combined diversity at all the levels of biological organization. It is related to all living plants, animals, and microbes found in their natural habitats. There are more than 20,000 species of ants, 3,00,000 species of beetles, 28,000 species of fishes and nearly 20,000 species of orchids. The biodiversity is measured at three levels; genetic diversity, species diversity and ecological diversity.
So, the correct answer is 'Living plants, animals and microbes found in their natural habitats'.

The difference between different living things with respect to their appearance and mode of life is called as

evs animal- the base of our life diversity in the living world environmental conservation and biodiversity biodiversity on earth and in india

  1. Classification

  2. Biodiversity

  3. Evolotion

  4. All of the above

Show answer
Correct Option: B
Explanation:

  • Biodiversity means the diversity of living forms. Different life forms have a different physical appearance. 
  • Some are tall, some are short and their mode of life is also different. For example, some are autotrophs some are heterotrophs, some organisms live in water or land or both.
Therefore, the correct answer is option B.

The totality of genes, species and ecosystems of a region is known as

  1. Biosphere

  2. Biodiversity

  3. Bioconservation

  4. Biocommunity

Show answer
Correct Option: B

Variety of organisms existing on the earth, their interrelationships and their relationship with the environment is called as

evs animal- the base of our life diversity in the living world environmental conservation and biodiversity biodiversity on earth and in india

  1. Diversity

  2. Biosphere

  3. Biology

  4. Biodiversity

Show answer
Correct Option: D
Explanation:

Biodiversity is the variation in living organisms from all sources such as terrestrial and aquatic ecosystems. It also involves the interaction of the biotic and abiotic factors with each other. Biodiversity is responsible for maintenance of balance in the ecosystem. Thus the correct answer is option D.

Measure of biodiversity of an area is

  1. The number of species found there

  2. The range of different life forms

  3. Both A and B

  4. None of the above

Show answer
Correct Option: C
Explanation:

Biodiversity is the variety of different types of life found on the Earth and the variations within species. It is a measure of the variety of organisms present in different ecosystems. Hence, the correct answer is option C.

The study of total number and types of organisms present on earth is

  1. Ecology

  2. Taxonomy

  3. Biodiversity

  4. Classification

Show answer
Correct Option: C
Explanation:

Biodiversity is the term used to describe the variety of life found on Earth and all of the natural processes. This can refer to genetic variation, ecosystem variation or species variation within an area, biome or planet. The biodiversity is more concentrated within the tropical ecosystems than temperate ecosystems. The most diverse group of animals are invertebrates. 
Some human activities have indirect but wide-reaching effects on biodiversity, including climate change and pollution. These threats have put a serious strain on the diversity of species on Earth.
