Question

1. (a) what are biotic factors? (b) give an example of a biotic factor. 2. (a) what is an abiotic factor? (b) give an example of an abiotic factor. 3. how are the components of an ecosystem linked? 4. how do the particular characteristics of an ecosystem arise?

Explanation:

1. (a) Biotic factors are the living components of an ecosystem.

(b) An example of a biotic factor is plants (or animals, fungi, bacteria etc.).

1. (a) Abiotic factors are the non - living components of an ecosystem.

(b) An example of an abiotic factor is water (or sunlight, soil, temperature etc.).

1. The components of an ecosystem are linked through interactions such as food chains/webs (energy flow) and nutrient cycling.
2. The particular characteristics of an ecosystem arise from the interactions between biotic and abiotic factors. For example, the type of plants (biotic) that can grow depends on the availability of water (abiotic), and these plants then affect the animals (biotic) that can live in the area.

Answer:

1. (a) Biotic factors are the living components of an ecosystem.

(b) Plants (or other living organisms).

1. (a) Abiotic factors are the non - living components of an ecosystem.

(b) Water (or sunlight, soil, temperature etc.).

1. Through energy flow (e.g., food chains/webs) and nutrient cycling.
2. From the interactions between biotic and abiotic factors.
