A Correct answer
Explanation

Forests help in maintaining a balance between Oxygen and Carbon dioxide in the atmosphere.
Plants in forest release oxygen through the process of photosynthesis and thus helps in providing oxygen for respiration.

What determines the limits of a biome

  1. Temperature and rain fall

  2. Type of soil

  3. Altitude and latitude

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • It is mostly the climate (temperature and precipitation) in an area, that determines its biome. This is because climate limits the species of plants, that can grow in an area. In turn, the species of plants determine the kinds of animals, that live there. 
  • A biome's boundaries are determined by climate more than any other factor. E.g., tundra is colder and has a shorter growing season than other biomes, it has fewer kinds of vegetation. 
  • Towards the equator, precipitation becomes increasingly important, producing temperate communities of desert, grassland, and forest in increasing order of precipitation. 
  • In the tropical and subtropical biomes, which occur in the equatorial latitudes, there is a relatively smaller range of temperatures during the year, and their variation is also determined by the amount of precipitation. 
  • Another important factor is the altitude. Changes in vegetation occur with increasing altitude. 
  • Soil is an important factor as it will determine the type of vegetation and biodiversity of that area. 
Thus, the correct answer is option D.

Species diversity is maximum in 

  1. Tropical rain forest

  2. Temperate forest

  3. Deserts

  4. Hillslopes
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The tropical rainforest is a biome located around the equator. It has the highest biodiversity of all the earth's ecosystems, both in flora and fauna as well as microbes. This high diversity is due to the optimal growing conditions at equatorial locations. Abundant rainfall and warm temperatures, as well as intense sunlight. 

Therefore, the correct answer is option A.

Which of the following communities is more vulnerable to invasion by outsider animals and plants?

  1. Mangroves

  2. Tropical evergreen forests

  3. Temperate forests

  4. Oceanic island communities
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some communities such as tropical oceanic islands appear to be particularly vulnerable to invasions. The vacant niche hypothesis suggests that island communities and some others are relatively impoverished in numbers of native species and thus cannot provide biological resistance to newcomers. Hence, they are most vulnerable.

Therefore, the correct answer is option D.

Major communities of the world are

  1. Scrubs, jungles and gardens

  2. Ocean, fresh water and forest communities

  3. Grassland and desert communities

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The living world is made up of different communities living in it. Some of these communities are the communities living in oceans, fresh water and forest communities, communities living in grasslands and deserts. These communities have different individuals belonging to them and have certain different characteristics. So, option D is the correct answer.

Which of the following communities are more vulnerable to invasion, by outside animals and plants?

  1. Tropical forests

  2. Mangroves

  3. Temperate forests

  4. Oceanic island communities
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oceanic island communities are more vulnerable to invasion by outside animals and plants than those of main lands. These islands include high volcanic-based islands like Hawaii and low coral islands like Marshalls. These areas are susceptible to invader impacts. This is due to lack of natural competitors and predators which control populations in the ecosystems.  

Thus, the correct answer is 'Oceanic island commuities.'

Multiple choice evs whose forests? conservation of forest and wildlife wildlife deforestation and conservation

Forest are called

  1. Kidneys of planet

  2. Heart of planet

  3. Lungs of planet

  4. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forest have been called the 'lungs of earth' because growing trees take carbon dioxide out of the air and replace it with oxygen. This is vital for humans, as we need oxygen in the air to breathe. As lungs take out the carbon dioxide from the body and supply oxygen to all parts of our body via nerves. Similarly forests also absorbs carbon dioxide from the surroundings and extract the oxygen from the trees.

So, the correct option is 'Lungs of planet'.
