What are the biotic and abiotic factors in the tundra?
Biotic factors are all the living things in an ecosystem, which includes all of the plants, animals, fungi, protists, and bacteria that make their homes there. Abiotic factors are the non-living parts of an ecosystem, and these include temperature, pressure, wind, sunlight, and weather systems.
What are 5 abiotic factors in the tundra?
Abiotic factors, or nonliving parts of the system, include:
What are the biotic factors in a tundra ecosystem?
Biotic Factors: Low Shrubs (sedges, reindeer mosses, liverworts, and grasses), Crustose and Foliose Lichen, Herbivores (lemmings, voles, caribou), Carnivores (arctic foxes, wolves, polar bears), Migratory Birds (ravens, snow buntings, falcons, loons), Insects (mosquitoes, flies, moths, grasshoppers), Fish (cod.
What are 3 abiotic factors in an ocean ecosystem?
Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.
What are some abiotic factors in the Arctic ecosystem?
Abiotic factors affecting life in the polar regions include temperature, sunlight and precipitation. The top layer of the ground remains frozen year-round, which prevents the growth of plants with deep roots such as trees. The poles receive weak sunlight while tilted away from the sun.
What are the 3 biotic factors?
Biotic factors have been divided into three main categories, which define their distinctive role in the ecosystem:
- Producers (Autotrophs)
- Consumers (heterotrophs)
- Decomposers (detritivores)
What are some abiotic factors of the Arctic ecosystem?
Abiotic factors affecting life in the polar regions include temperature, sunlight and precipitation. The top layer of the ground remains frozen year-round, which prevents the growth of plants with deep roots such as trees.
