The tundra ecosystem of Alaska is known as a “cold desert.” It receives very little precipitation, about four inches annually. H
owever, it is rich in wetlands due to permafrost, which traps moisture close to the surface. The temperatures vary widely, also producing persistent winds. Although treeless, the Arctic tundra is an abundant ecosystem. Many organisms find their niche here including many migratory bird species and mammals such as caribou, foxes, bears, and small rodents. Which element of the tundra ecosystem is biotic?
Biotic factors of tundra ecosystem: migratory bird species and mammals such as caribou, foxes, bears, and small rodents.
Explanation:
Biotic component of an ecosystem are the total of all the species of living beings present in the system. It includes species of plant, animals and microbes. Since tundra ecosystem is habitat for migratory bird species and mammals such as caribou, foxes, bears, and small rodents; these living beings serve as biotic component for the system.
There are many known positive outcomes of genetic engineering both in plant and animals. Among these outcomes include: a. elimination of diseases; b. most desirable traits guaranteed to exist; c. crops that can be pest and disease resistant; d. longer shelf life for plants.
