What are abiotic factors in a habitat?
What are abiotic factors in a habitat?
- Non-living environmental factors like water and soil (correct)
- Living organisms and their interactions
- Biotic components including plants and animals
- Symbiotic relationships among species
How does a mutation become an adaptation?
How does a mutation become an adaptation?
- It increases the chances of survival in a habitat (correct)
- It causes a decrease in reproductive success
- It results in the species becoming extinct
- It leads to a reduction in competition

What does a niche represent in an ecosystem?
- The complex interactions of a species within its environment (correct)
- The genetic variety within a species
- The species' ability to control abiotic factors
- Only the physical space where a species lives

Study Notes
Habitat Requirements for Species
- A habitat is the place where a species lives, including both biotic (living) and abiotic (non-living) factors
- Biotic factors include plants, animals, bacteria, and waste products
- Abiotic factors include water, soil type, and climate
- Every species has a tolerance range for abiotic factors; populations die outside this range
- The optimal value of an abiotic factor is where the largest number of individuals of a species is found
Mutations and Adaptation
- Mutations create differences in the DNA of individuals
- An adaptation is a mutation that enhances survival in a specific habitat
- Organisms with adaptations have higher fitness (more offspring)
- This increased rate of organisms with the adaptation leads to an increase in the likelihood of the adaptation continuing
- Natural selection is the process where these adaptations become more common over time
Species Niches
- A niche describes the complex interactions of a species within its environment, including its role or function
- A species' niche can be seen as the role or function it has in the ecosystem
- Different species can co-exist in the same ecosystem by occupying different niches, avoiding competition
