Question

Which examples represent abiotic factors affecting biotic factors? Check all that apply.
-sediment builds up in a riverbed, slowing the river's speed.
-ash from a volcanic eruption kills new plant growth.
-a hungry raccoon consumes a freshwater clam.
-warm water from a nuclear power plant causes overgrowth of algae.
-a river floods and deposits tree pollen along its banks.​

Answer 1

Answer:

B-ash from a volcanic eruption kills new plant growth.

D-warm water from a nuclear power plant causes overgrowth of algae.

E-a river floods and deposits tree pollen along its banks.​

Explanation:

Ecosystem consist of biotic and abiotic elements. Biotic refers to all living organisms while abiotic refers to all non-living elements of the environment. Living organisms depends on abiotic factors such as light, temperature, water and soil etc for their growth and survival. In the above answer, Ash of volcano, warm water and rivers are abiotic elements while plant, algae and pollen are biotic elements.

Answer 2

The non-living chemical and physical components that are part of the ecology and environment is called abiotic factor while biotic factors are living organism that is part of the ecosystem.

The correct examples are:

• Option B. Ash from a volcanic eruption kills new plant growth.

• Option D. Warm water from a nuclear power plant causes the overgrowth of algae.

• Option E. A river floods and deposits tree pollen along its banks.​

The effects can be explained as:

• Abiotic factors like temperature, water, air, soil etc. affect the biotic factors like plants and animals of an ecosystem.

• Ash from volcanoes and warm water discharged from nuclear plants are abiotic factors that affect the growth of biotic factors like plant and algae.

Thus, options B, D and E are correct choices.
