Get to know insects

There are many types of insects with different shapes. They are arthropods among invertebrates. They are the largest group of animals on the earth, accounting for more than 50% of all biological species. Their traces can be found in almost every corner of the world.

Until the beginning of the 21st century, there were more than 1 million species of insects known to humans, but there are still many species that have yet to be discovered. Insects are the largest group of arthropods. The most common ones are locusts, butterflies, bees, dragonflies, flies, grasshoppers, cockroaches, etc.

Not only are there many types of insects, but the number of individuals of the same species is also staggering. The distribution of insects is so wide that no other class of animals can compare with it, almost all over the earth. There are different types.

Get to know birds

Birds are adapted to flying life, and their skeletal systems are significantly specialized, showing that their bones are light and strong, and their bones have gas-filled cavities.

Birds have many special adaptations that allow them to live in a variety of environments.

The food habits of birds can be divided into carnivorous, fish-eating, insectivorous and plant-eating types, as well as many intermediate and omnivorous types. The feeding habits of some species vary depending on seasonal changes, food availability, habitat characteristics, and other conditions. By analyzing the bird's beak, you can determine its feeding habits.

Birds control or eliminate various pests and wild rats and protect forests and crops. Some birds (such as many species) eat weed seeds, which is of considerable benefit to agriculture. Some birds (such as flowerpeckers, sunbirds, etc.) can spread pollen, which is beneficial to the fruiting of plants.
