What is the role of bees in natural ecosystems

Bees are a beekeeping ecosystem.

is also a common member of the entire natural ecosystem. The following will focus on several aspects of the role of bees in natural ecosystems.

1) Provide bee products: honey and royal jelly produced by beekeeping.

Bee pollen, propolis.

Beeswax, bee larvae, bee pupa.

and other bee products, which are highly nutritious and have a wide range of uses.

2) Pollination of nectar plants: plant flowering, plant fruiting, carnivores, carnivores, ......from the above food chain.

It can be seen that without bee pollination, which interrupts the flowering and fruiting process, the frucidagoes and carnivores will be greatly reduced due to starvation, and even face the danger of extinction. American ecologist Ambrose and wildlife scientist Buddick have found that many wild animals feed on the fruits of plants that rely on bees for pollination.

Therefore, bees play an important bridging role in the food chain in natural ecosystems.

3) Control of plant pests: Ningxia, northern Shaanxi.

of farmers often give sand dates medicine to treat aphids.

However, in recent years, it has been found that because there are people who come to release bees when the date of flowering, even if the date is not sprayed, there are few aphids on the tree. Here's why:

Aphids absorb nutrients from dates as food, harming trees and excreting nectar honey. Before no one came to the forest to release bees, the willing honey secreted by aphids has always been the food of ants in the forest.

The abundance of manna honey encourages ants to multiply, and ants are the direct dependence of aphids for successful wintering. When someone came to release bees, because the bees and ants competed for food, nectar honey, many ant colonies in the jujube forest died due to food shortage, so that the aphids could not overwinter smoothly, and naturally the aphids on the jujube trees decreased greatly the following year.

Western honey bees in China's natural ecosystem, in the ecological niche.

Although there is a lot of overlap between the upper and middle bees, there are many differences in their individual characteristics, such as the worker bees of the western honey bee have a lower sense of smell and are not easy to find scattered, sporadic flowering low shrubs and herbaceous plants.

Such as cruciferous.

Rosewood, Sumacaceae, Camelliaceae, Pentaceae, Lamiaceae, Asteraceae, Cucurbitaceae, etc. The plants of these species are scattered, dwarf, and mostly grow in shade. When it blooms, the middle bee is the main flower picker, and the worker bees of the western honey bee rarely go.

In addition, in the same collection area, the daily collection time of Chinese bees was earlier and later than that of Italian bees, generally 2 3 h longer. As a result, the breadth and depth of pollination of native plants by Chinese bees exceeds that of Western honey bees. The replacement of the Chinese bee by the western honey bee led to a decrease in the total pollination of local plants, which affected the pollination of many plants, and the population of some species gradually decreased until they eventually became extinct, resulting in a decrease in plant diversity in mountain forests.

Question Answers: (1) Producer; pollinator (2) decomposer; Substance (3) food chain.

1. Environment: Bees generally live in places where they are cool in winter and warm in summer and rarely disturbed by people and animals, and the hive built by bees with beeswax does not have the effect of sheltering from wind and rain, so the place where bees build their nests also requires that they must be able to shelter from the wind and rain, such as stone caves, rock crevices, and tree holes in secluded places are ideal nesting locations for bees.

2. Nectar source: Bees generally live in nearby places with abundant and relatively continuous nectar sources, the reason is that bees are insects that feed entirely on flowers (including nectar and pollen), and the effective collection radius of bees is actually only 2 3 kilometers, in fact, bees will basically build nests in nearby places with rich and relatively continuous nectar sources.

3. Enemies: Bees generally live in hidden and conducive to bee colonies to resist predators, in fact, bees also have many natural enemies in nature, such as wasps, spiders, dragonflies, etc. will hunt and kill bees, especially the wasps pose the greatest threat to bees, so bees build nests in hidden and narrow holes in stone holes or tree holes.

From the perspective of the environment, bees mostly build their nests in places that are rarely disturbed by people and animals and can shelter from the wind and rain, from the perspective of honey sources, bees mostly build nests in places with abundant and relatively continuous honey sources nearby, and bees mostly build nests in stone caves or tree holes that are hidden and narrow holes from the perspective of defending against enemies.

The environment in which bees grow is in nature, with fragrant flowers and busy bees at work.

The temperature and humidity are more suitable for the survival of the seal, and there should be a nectar source for collecting honey to ensure that the food of the bees is sufficient, and the bees have such a suitable environment, and the bees will live normally.

The living environment is relatively humid, and living in a box like a lattice, such an environment can better help them store honey, and can make honey crystallize better.

As an ectothermic insect, bees are best suited for temperatures of 15 to 25 and relative humidity of 77 to 84%.

You need to live at about 20, and the humidity should be around 80% as much as possible, so as to better ensure life.

a.Earthworms improve the soil and increase its fertility: Moxiao Mountain is clearly to maintain ecological balance.

b.Rats burrow and turn saline land into fertile land: not to mention, dFrogs can control the pest population: when blind, it is necessary to maintain ecological balance.

So the answer is obviously cBecause bee pollination is an animal instinct.
