The farming methods promoted by the California Ricelands Habitat Partnership are best described as beneficial to both farmers and wetland species because .
a.
migrating waterfowl use flooded rice paddies on their travel routes
b.
foraging birds eat leftover rice and trample the ground making tilling unnecessary
c.
farmers need migrating bird guano as fertilizer
d.
California’s wetlands are dwindling

b.  

Explanation:

The California Ricelands Habitat Partnership is defined as a partnership between conservation groups  and rice farmers in order to maintain the habitat for waterbirds and other wildlife in California's Sacramento Valley.

The partnership was beneficial for both farmers and wetland species because the foraging or waterbirds use to eat the leftover rice and also contribute to the land removing unnecessary tilling in the ground.

Like this, both get benefit from partnership  as birds get food and farmer get rid of tilling.

Hence, the correct option is b.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
