Understanding Ecology: Biotic and Abiotic Interactions in Ecosystems

DESCRIPTION

This overview of ecology explores the intricate relationships between biotic (living) and abiotic (non-living) factors in various ecosystems. It defines key concepts, such as ecosystems, biomes, and the levels of organization in nature. Examples of biotic factors (plants, animals, fungi) and abiotic factors (air, water, soil) are provided. The document highlights how these components interact and influence each other through processes like migration, competition, and mutualism. Understanding these dynamics is crucial to studying environmental changes and preserving biodiversity.

  5. Examples of Biotic Factors

  6. A Abiotic Factors include air, water, soil, temperature, wind, source of energy (usually sun) a, an (G) prefix not, without abiotic amoral amusia atoxic

  7. Examples of Abiotic Factors

  8. Examples of Ecosystems Coral Reef in Belize Mountains in Colorado Arizona Desert

  9. Ecosystems do not necessarily have clear boundaries due to biotic and abiotic changes can change daily as things move from one ecosystem to another Biotic Abiotic migration, seed dispersal flood, erosion, drought

  10. Biotic Factors interact with each other in complex ways parasitism mutualism competition such as also interact with abiotic factors in the ecosystem dependent upon water, minerals, temperature, light

  11. Biome a major regional or global biotic community, a super ecosystem, defined chiefly by the dominant forms of plant life and the prevailing climate

  12. Major Biomes of the World desert grassland tropical rain forest deciduous forest coniferous forest tundra ocean

  15. 12.1 Questions 1-5

  16. Research Questions • Draw a diagram of an ecosystem near where you live . Label the factors “biotic” or “abiotic.” • Give two examples of how plants and animals affect their environment • Describe how temperature, light, and soil affect an ecosystem • Think of a forest ecosystem. Now imagine that a large amounts of dust and ash into the air, blocking out sunlight. How might the forest ecosystem be affected if the sunlight is blocked out for a day? For a year?
