  2. biotic factors

  3. biologic factors

  4. antibiotic factors

The prefix "a-" means "not" or "without" and "biotic" means living, so abiotic factors are the non-living parts of an ecosystem. Examples include sunlight, temperature, wind, water, and soil.

Multiple choice
  1. renewable & nonrenewable resources

  2. oxygen & water

  3. availability & community

  4. biotic & abiotic factors

D Correct answer
Explanation

The distribution and abundance of any species are determined by both living (biotic) interactions, such as predation and competition, and non-living (abiotic) conditions, such as temperature and water availability. Together, these two categories encompass all environmental influences on organisms.
