Слайды и текст этой презентации
Слайд 2The most numerous animals on Earth are insects. They form
about 75 percent of the animal kingdom.
Слайд 5Some insects live in colonies.
Many insects can fly, which makes
it easy for them to colonize new places.
Слайд 6 WHAT
DO INSECTS EAT?
Insects eat a huge range of foods. Around
half are plant-eaters, feeding on leaves, roots, seeds, nectar, or wood. Fleas and lice are parasites, eating the flesh or blood of larger animals without killing them.
Слайд 7WHERE DO INSECTS GO IN WINTER?
Some adult insects die off
in winter. Their eggs or young survive in sheltered places
and emerge in spring.Others, such as monarch butterflies, migrate long distances to avoid the winter chill.
Слайд 8 HOW DO INSECTS
AFFECT HUMANS?
Plant-eating insects can harm crops and fruit trees. Wood-munching
insects destroy homes and furniture, while biting insects can spread disease. However, many insects are helpful to humans—for example, honeybees make honey and silkworms produce silk.
Слайд 9
FACINATING FACTS ABOUT
ANIMALS
Insects have many different ways of communicating. They communicate through
touch with their antennae and mouths.Insects don’t need much water, however: a simple raindrop will do.
An Australian tiger beetle is the world’s fastest running insect. It can reach speeds of 9 kilometers per hour.
The fastest flying insect is Horse Fly. Its fastest recorded speed is 145 km per hour.
