Answer 2

Answer:

1. Flying Mammals
2. Flying MammalsBats are true mammals in that they give birth to live young, produce milk to feed their young, have hair, and they are warm-blooded (they can self-regulate their body temperature). Bats are unique among mammals in that they can fly.
3. The leguminous plant increases the soil ripeness due to the Rhizobium bacteria in the root knobs of the plants. These microscopic bacteria changes over atmospheric nitrogen to a shape which can be utilized by plants. This reduces the nitrogen deficiency in the soil and makes it abundant
4. By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. ... Nitrogen in the casts is readily available to plants.
5. Roughage is the portion of plant foods, such as whole grains, nuts, seeds, legumes, fruits, and vegetables, that your body can't digest. However, it's an important food source for the beneficial bacteria in your gut. It may also aid weight management and decrease certain risk factors for heart disease.
6. living room in the house should get direct sunlight at least for a short time? Direct sunlight contains ultraviolet radiations of the sun, which help in killing of mould spores present in air
