Answer

Brief Explanations:

  1. Succession is the regular progression of species replacement.
  2. Abiotic factors are non - living factors like weather.
  3. Ecology is the study of living things and their interactions.
  4. Pioneer species are the first plants or mosses in a new ecosystem.
  5. Biodiversity represents the variety and genetic differences in an ecosystem.
  6. An ecosystem consists of a community and physical aspects of the habitat.
  7. The biosphere is the life - sustaining portion of the planet.
  8. The community is all different species living together in an ecosystem.
  9. Secondary succession occurs where there was previous growth.
  10. Biotic factors are living factors in an ecosystem.
  11. Primary succession occurs where there was no previous growth or soil.
  12. A biome is part of the biosphere with a specific climate and community.
  13. Example of primary succession: New island formation from volcanic activity.
  14. Example of secondary succession: Forest regrowth after a fire.
  15. Producers are essential as they convert sunlight into energy (via photosynthesis), forming the base of the food chain.
  16. Decomposers are essential as they break down dead organisms, recycling nutrients back into the ecosystem.
  17. In a marine food web, algae have more biomass than killer whales because energy transfer between trophic levels is inefficient. Most energy is lost as heat at each level, so primary producers (algae) need to have a large biomass to support higher - level consumers like killer whales.
