Biodiversity and Conservation Questions

Multiple choice evs - i dwelling places of animals threatened species need of conservation conservation of soil and wild life

Wild life is affected to maximum when

  1. Protection and care is less

  2. Hunting and poaching is carried out

  3. Natural calamities occur

  4. Natural habitat is destroyed
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wild animals can survive and grow best when they are in their natural habitats. So, the destruction of their natural habitats affect them adversely and their development is impaired.

So, option D is the correct answer.

Multiple choice geography secondary sector : industry generation of electricity exploration and conservation of minerals irrigation and power

Life of organisms in ecosystem is threatened due to _____.

  1. Urbanization

  2. Industrialization

  3. Introduction of toxics in ecosystem

  4. Rapid housing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An ecosystem can be defined as a biological community with interacting organism and their physical environment. Though urbanization and industrialization may disturb the ecosystem to an extent, introduction of toxins into environment will spoil the ecosystem from its roots.

Multiple choice social science greenery in telangana pollution of soil degradation of land damaging the forests

How are the wild animals affected by cutting of forest?

  1. Number decreases

  2. Color of skin will be affected

  3. Ability of homeostasis will decrease

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seventy percent of the world's plants and animals live in forests and are losing their habitats to deforestation (cutting of forest), Loss of habitat can lead to species extinction. The number of wild animals decreases by cutting of forest because If the trees are gone, birds, reptiles, and insects lose their homes and food sources. That will affect the small mammals, which are a food source for mid- and large-sized mammals. It is a cascade effect that leads to species extinction. So, the correct answer is 'Number decreases'.

Multiple choice

Which of the following is NOT a way that biodiversity can be lost?

  1. urbanization

  2. recycling

  3. mining resouces

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

Recycling is a method used to conserve resources and protect the environment, whereas urbanization, mining, and overfishing are activities that typically lead to habitat destruction and loss of biodiversity.

  2. wetland sites under the threat of anthropogenic activities.

  3. endangered species of tropical and sub-tropical fauna.

  4. coastal cities under direct threat of consequences of global warming.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Montreux Record is maintained as part of the Ramsar List. It highlights Ramsar wetland sites where ecological character has changed, is changing, or is likely to change due to human activities, pollution, or technological developments.

Multiple choice

What is the biggest threat to the Rainforest? 

  1. Forest Fires

  2. Animals Eating Trees

  3. Chopping down trees

  4. Climate change
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deforestation, primarily driven by logging and clearing land for agriculture, is widely considered the most immediate and significant threat to rainforest ecosystems. This activity destroys critical habitats and accelerates climate change.

Multiple choice

Why is deforestation so devastating to a habitat?

  1. It provides more vegetation for herbivores.

  2. It creates new space for plants and animals.

  3. It increases levels of oxygen created by plants.

  4. It threatens the survival of plant and animal species.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation destroys the complex ecosystems that provide food, shelter, and breeding grounds for countless organisms. By removing these habitats, it directly threatens the survival of numerous plant and animal species, leading to biodiversity loss.

Multiple choice

Which of the following is one of the biggest threats to endangered species?

  1. oil drilling

  2. habitat loss

  3. air pollution

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

Habitat loss, driven by human activities like agriculture, urbanization, and deforestation, is widely recognized as the primary threat to biodiversity and endangered species worldwide. Without a suitable place to live and find food, species cannot survive.

Multiple choice

Which of these processes most threatens biodiversity?

  1. predation

  2. Earth's orbital cycles

  3. evolution

  4. industrial agriculture
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Industrial agriculture involves large-scale land clearing (deforestation), monoculture farming, and heavy pesticide use, all of which destroy diverse natural habitats and significantly threaten global biodiversity. Natural processes like predation and evolution actually support or maintain biodiversity.
