Question

5
Write the
producers
differences between
and consumers.​

Answer 1

➢ Producers

Producers are autotrophic organisms that can synthesize organic matter using simple inorganic matter. Being able to convert solar energy into chemical energy through photosynthesis, and convert inorganic matter into organic matter not only supply its own development and growth, but also provide materials and energy for other organisms, occupying the most important position in the ecosystem.

In freshwater ecosystems, mainly phytoplankton-algae are produced, as well as some rooted plants or floating plants that grow in shallow water (plants in freshwater ecosystems are divided into: floating plants, emergent plants, and diving plants). The producers of forest and grassland ecosystems are green plants such as herbs, shrubs, and trees. In the deep sea and other similar ecosystems, producers can use the chemical energy of reduced inorganic substances such as hydrogen sulfide to synthesize bacteria (sulfur bacteria).

➢ Consumers

Consumers are a biome in nature, and heterotrophic organisms, including herbivores and carnivores, are called consumers. As the name implies, these consumers cannot directly use solar energy to produce food, they can only obtain energy by directly or indirectly feeding on green plants. According to different feeding status, it can be divided into first-level consumers who directly depend on the branches, leaves, fruits, seeds and litter of plants, such as grasshoppers such as locusts, hares, deer, cattle, horses, and sheep; Carnivorous animals that feed on herbivores are second-level consumers, such as weasel, fox, frog, etc .; there is a relationship between weak meat and strong food among carnivores, and the strong ones become third- and fourth-level consumers. These advanced consumers are the most ferocious carnivores in the biome, such as lions, tigers, eagles and sharks in the waters. Some animals eat both plants and animals, called omnivores, such as certain birds and fish. Consumers are in the middle link in the process of material and energy conversion in the ecosystem.
