How are birds useful for the human beings ?
Answers
Explanation:
Birds are important members of many
ecosystems. They play a vital role in
controlling pests, acting as pollinators, and
maintaining island ecology. In addition,
birds are important to humans in many
ways, such as serving as a source of food
and providing fertilizer in agricultural
settings.
Birds are obviously important members of
many ecosystems. They are integral parts
of food chains and food webs. In a
woodland ecosystem for example, some
birds get their food mainly from plants.
Others chiefly eat small animals, such as
insects or earthworms. Birds and bird
eggs, in turn, serve as food for such
animals as foxes, raccoons, and snakes.
The feeding relationships among all the
animals in an ecosystem help prevent any
one species from becoming too numerous.
Birds play a vital role in keeping this
balance of nature. In addition to being
important parts of food webs, birds play
other roles within ecosystems.
1. Birds eat insects. They are a natural way
to control pests in gardens, on farms,
and other places. A group of birds
gliding through the air can easily eat
hundreds of insects each day. Insect
eating birds include warblers, bluebirds
and woodpeckers.
2. Nectar-feeding birds are important
pollinators, meaning they move the
pollen from flower to flower to help
fertilize the sex cells and create new
plants. Hummingbirds, sunbirds, and the
honey-eaters are common pollinators.
3. Many fruit-eating birds help disperse
seeds. After eating fruit, they carry the
seeds in their intestines and deposit
them in new places. Fruit-eating birds
include mockingbirds, orioles, finches
and robins.
4. Birds are often important to island
ecology. In New Zealand, the kereru and
kokako are important browsers, or
animals that eat or nibble on leaves,
tender young shoots, or other
vegetation. Seabirds add
nutrients to soil and to water with their
production of guano, their dung.

they are essential seed dispersers for plants that provide us with food, medicine, timber, and recreation. Among their qualifications: They travel long distances. They assist germination when they eat fruit by removing the pulp and scratching the seed coat.
