Question

1. explain the difference between biotic and abiotic factors, and give three examples of each.

1. define niche and habitat. how do they differ?

Explanation:

• Question 4: Biotic factors are living components in an ecosystem (e.g., plants, animals, fungi). Abiotic factors are non - living components (e.g., sunlight, water, soil).
• Question 5: A habitat is the physical place where an organism lives. A niche is the role and position an organism has in its environment (including how it meets its needs for food, shelter, etc.). The main difference is that habitat is about the 'address' and niche is about the 'job' or function of the organism in the ecosystem.

Answer:

• Question 4: Biotic factors: plants (e.g., grass), animals (e.g., deer), fungi (e.g., mushrooms). Abiotic factors: sunlight, water, soil.
• Question 5: Habitat: physical living place. Niche: role/position in the environment. Difference: habitat is where, niche is what it does (function).
